How Dock Lights Work

In order to successfully fish at dock lights, you need to first understand how they work. While lit under the water, the bulbs reflect off microorganisms. This reflection attracts small baitfish and minnows to the light. These baitfish, in turn, attract larger predator fish. Essentially, these dock lights create a food chain right next to your dock!

Because the dock lights automatically turn on each day, the fish will become used to the feeding cycle produced. The longer your dock lights are in the water, the more predator fish you will see. Depending on your location, you can see many different species of fish, such as snook, tarpon, redfish, ladyfish, and much more.

Choosing the Right Bait & Lures

The most important thing to do before fishing these lights is choosing the right bait or lure. Take a few moments to watch the lights and see what type of baitfish are swimming around. After watching the light, try to match what is on your hook to the bait surrounding the light. For example, if you use a shrimp lure at a dock light full of small minnows, the smart predator fish, will not give you the time of day. For the most part, small minnows will be the best choice for lures or bait. Shrimp are only apparent in waterways with a steady current, which is not the case for most dock lights that are popular in homeowner canals.

Monkey See, Monkey Do

The baitfish perform a circular pattern once attracted from the dock lights. Because of this, it will be easier for you to choose which bait or lure to cast into the water.  When casting, aim past the light and into the shadows. Then slowly reel in your bait or lure at the same speed as the other bait swimming through the light. Also, if possible, try to match the swim patterns of the baitfish (circle, darting, etc..). By matching the speed and behavior of the baitfish, you stand a better chance of attracting the predator fish who are at the lights.

At Underwater Fish Light, we strive to build the best dock lights on the market. All of our lights are built in the United States and come with a three-year warranty.

Dock Lighting With A Purpose

When it comes to outdoor lighting for your dock, there are many things to consider. Sometimes, people like to choose the items that look the “coolest.” However, that might not be the best strategy. It’s important to choose products that not only look great, but serve an important purpose. So, this blog will be focused on the best purposeful outdoor lighting for your dock.

Solar Piling Caps

Solar piling caps are a great way to illuminate your dock. These amazing piling caps will serve multiple purposes when it comes to protecting your dock. First, it will illuminate the area on and around your dock with pleasant ambient lighting. This will make it safer and more enjoyable for you and your family. Second, these lights will also make your dock more visible to other boaters that might be navigating through the canal at night, to help prevent any marine accidents. Lastly, these solar piling caps also protect your pilings like regular piling caps, but with extra flare!

Pathway Dock Lighting

Our Dock Blocks are one of our most popular dock lighting items! Have you ever worried about someone walking off the edge of your dock at night? These little guys can help. They not only look awesome, but they help keep you, and anyone else on your dock, safe! These solar lights are incredibly easy to install, and last for years. Just attached them to your dock with two screws, and wait for the sun to go down!

Fish Lights

It’s no surprise that those who live in waterfront homes love the water. Whether it’s boating, fishing, or just enjoying nature, there are many benefits to having a dock. One of the best outdoor lighting accessories for your dock is an Underwater Fish Light! It’s a great addition for those who love to fish, or just to watch the beauties of the natural environment at night. Fish lights not only provide an amazing form of entertainment for you and your family, they also have an important safety aspect. Just like the DokLite solar piling caps, Underwater Fish Lights illuminate your dock. That way, if anyone is traveling the canals at night, your dock is safer from possible marine accidents.


Get To Know The Snook

Our Underwater Fish Lights aren’t called “snook lights” for no reason! The longer your light is in the water, the more fish you are going to see. One of the most popular inshore species of fish our customers see is the snook. Our lights will also attract tarpon, redfish, and many more predator fish species.

Some customers purchase our dock lights to make it easier to see and catch snook, and they are never disappointed! Snook are one of the most popular inshore gamefish. They are caught recreationally in the Gulf of Mexico, as well as the Atlantic. Commercial fishing of snook has been prohibited in multiple states. Because of this, most of the targeting of snook is done by recreational fishermen.

Know Where To Look

Snook generally like to hang out in mangroves, but also around bridges, docks, and other structures. So, when you see a dock light, you will most likely see snook swimming around. Most snook will be hanging out in the shadows. They might only swim through the light to strike at a bait fish that was attracted to the light. 

Fake It Till You Make It

They key to landing a snook at a fish light is simple. Just act as much like the baitfish as possible. Obviously, we don’t mean you should jump in the water and start swimming around the light. We’re referring to what you have on your hook. You’ll want to ensure your lure or live bait are swimming in the patterns as the other fish around the light.

If you do not see much shrimp at your dock light, then we suggest against using shrimp bait or lures on your hook. If you see mostly small minnows, then choose a lure that matches those species.

Once you have something on your hook that resembles the rest of the baitfish, it’s time to start casting. You’ll want to cast out into the shadows passed the light, then reel your line in through the fish light. This will keep your lure from scaring everything in the light when it “plops” into the water.

Just keep casting in a pattern matching the bait fish and within a few casts, you should have a fish on! 

Don’t Lose It!

When you hook the snook, it’s going to be a little bit of a fight depending on the size. Snook are smart, and they’ll try to lose the hook by jumping, or swimming under and through different structures. When you first hook the snook, try to steer it away from the dock pilings and any other waterway obstructions. For many fishermen, once the snook juts under a dock, the fight is lost. So, stay vigilant and have fun! Snook are one of the most fun inshore species of fish to catch! Good luck and tight lines to all!


When it comes to fishing off a pier or dock, using an LED Fish Light can make things much more fun! Here are a few tips to help make your LED dock light fishing trips more successful:

1. Location location location

LED fish lights only attract fish that are in the area. If you take your fish out to a dock or pier that doesn’t have much fish traffic, you’ll be sorely disappointed. These lights don’t make fish appear out of thin air. The fish already have to be int he general area in order for them to work. Using these lights at your favorite pier or honey hole, will bring you great results! If you happen to throw the light into a dead area, you sadly won’t see much.

2. Don’t Rush Into It

When you first throw your LED light into the water, give it some time before you start throwing lines out. Give the fish some time to notice, and become attracted to the light. LED dock lights are a magic magnet that brings the fish immediately to you. These lights build a natural food source for the fish. When the light from the LEDs reflect off the particles in the water, it attracts baitfish. After the baitfish start swarming, you’ll see the predator fish start to come too. This process takes time, so we suggest to throw the light in, then come back a little later. We like to throw our LED fishing lights into the water, then get all of our fishing gear ready. This gives the light time to do its thing while you get ready for a full night of fun.

3. Watch and Learn

Once you see the fish start to come towards the light, watch their behavior for a little bit. Try to find the patterns the baitfish are swimming in. Also, try to pinpoint which baitfish the larger predator fish tend to gravitate towards. This little bit of time isn’t just relaxing, it helps you formulate a game plan for your retrieval strategies later. This extra little time also lets the fish become comfortable in the light. You don’t want to spook them away from the spot before you even get a chance to catch any of them!

4. Monkey See, Monkey Do!

Now that you know the patterns the fish are swimming in, you can finally throw out your line! It’s important to ensure that you’re retrieval patterns match the same behavior as the other baitfish that are swimming around. Predator fish light snook, tarpon, and redfish aren’t dumb! They can sense when something is off.

Have fun!

This is the most important thing! We build these great dock lights to bring enjoyment to everyone who has the pleasure to use them! We hope you enjoy your light and bring in the catch of a lifetime!


Get The Most Out Of Your Dock Lights

So you just bought your new fish light, and you’re so excited to see what it’s going to bring to your dock. All of us here at Underwater Fish Light know exactly how you feel. We’ve had the excitement of setting up the light and waiting for night to fall. Now that you’re enjoying your light, you can’t help but wonder “what else can I get for my dock?” We also had that same problem. Because of this, we created and added things to our product line that will enhance you experience with our Dock Lights and make your time spent on your dock more enjoyable.

Mounting Plaque

The Mounting Plaques are a great addition to your new dock lights. The plaque will ensure the control box will stay securely in place, even in some of the roughest weather. Some of the control boxes for our larger systems are much wider than the pilings themselves, so a mounting plaque would be almost essential to ensure the longevity of your system.

Timer Photocell

The timer photocell is a great way to create a schedule for the operation of your dock lights. If you would like your light to turn off at a specific time during the night, just set the dial to your desired time. This type of customization comes in handy for those not wanting the light to run all night, or to shut it off before the other nighttime fishermen start trolling the canals.

3. Self-Filtering Livewell

If you have an Underwater Fish Light, you know how easy it is to collect bait. Whether you catch your baitfish off your Underwater Fish Light, or purchase it from your local bait shop, it’s important to not let it go to waste! The Livewell by Underwater Fish Light is custom made to your specifications, to ensure it fits on your dock perfectly. This Livewell will keep your bait alive for days, thanks to its water filtration system. Never let your bait die again! Get one now!

2. Single Dock Light

Anyone with a dock, knows there is a lot of life under the surface they can’t see. What’s the best way to solve that? Illuminate it!

A single Underwater Fish Light is one of the best dock accessories available. You’ll discover an entire new world of activity that has been under the surface all along! These systems attract fish by reflecting off microorganisms in the water. These reflections attract baitfish, which in turn attract predator fish like snook, tarpon, redfish, bass, and many more!

1. Double Dock Light

Get twice the lights for twice the fun! The more lights you have under the water, the more reflection. This means you’ll be able to seen more bait fish & predator fish! These systems are the exact same as our single systems, but they have two bulbs each on their own individual wires. With two lights, you will have twice the amount of microorganisms reflect from the light, therefore attracting more baitfish and predator fish! 


The Mystery Of Night Fishing

Let’s state the obvious. For many fishermen, when the sun starts to go down, they start to head in for the night. What a lot of people don’t realize, is that they’re heading in right before the fishing reaches its peak! Don’t let the darkness scare you. Under the surface, there are hundreds of snook just waiting to snatch up your lure and get reeled in!

Snook Lights Are The New Honey Hole

While night fishing, you no longer have to guess and search for a good spot all night. You already know where the fish are! It doesn’t matter if you have a snook light of your own, or if you know where to find one. Just search for that classic green glow in the water and start casting.

Thanks to snook lights, you’ll no longer have to take your boat out to a spot half an hour away from the boat ramp to get to the fish. Now, the fish come to you! Just light up your snook light, and wait for them to swarm. We all know grandpa had that special spot growing up where he knew he would get a bite. Yeah, it was kind of a pain to get all the way out there, but at least you came back with fish every time. Snook lights bring all of the fun and fish straight to you without the need for all the travel time! Now, you can enjoy time with your family and friends while catching fish and making more memories.


You’ve got to be prepared!

1. A Headlamp

It’s not very shocking that it’s dark while you’re out night fishing. This might be an obvious choice when going dock light fishing, but many people forget about it! All of us here at Underwater Fish Light have been stuck out in the dark without a headlamp, and trust me, it was not fun. These great energizer headlamps are cheap and work great! There are also some other light configurations like light clips, or just a flashlight, but we’ve found that it’s easier to use the handsfree headlamp that will turn in the direction you’re looking at.

2. DOA TerrorEyz

The DOA TerrorEyz lure is a GREAT choice when it comes dock light fishing. No matter how many lures you put in your tackle box, this small minnow should definitely be one of them!

3. Tsunami Pliers

The Tsunami Fishing Fliers are an essential tool to your tackle box. Many fishermen will tell you how useful a pair of pliers are, and they’re not lying!

4. Vanish Fluorocarbon Leader

Vanish Fluocarbon Leader is a great choice for a leader. You’ll want to make sure that the fish you’re targeting can’t see your leader. Vanish Fluorocarbon Leader will help you use effective lures without spooking any of the fish!

5. DOA Bait Buster

One more shoutout for DOA is the DOA Bait Buster! We suggest using the Deep Runner Bait Busters. The bigger guys usually like to swim deeper!


If you’re not a night fisherman, you may be missing out.

Night fishing exposes you to those night feeders that just don’t come out during the day. Many species are simply more active at night. There are numerous reasons, some of which are tides and moon phase. Water temperature is cooler, especially in summer months. Many fish tend to dive to deeper waters during the heat of the day. But for whatever reason, many fish are just far more active at night. Although fish don’t see well at night, many fish rely on movement and smell to locate food sources.

As a fisherman, it may be harder to maneuver at night, but that’s where the use of fish lights can be advantageous, not only for you, but also the fish. Fish can be triggered into a feeding frenzy once you introduce a light source, in particular, a submersible one.

Submersible fish lights directly project into the water and cause reflections. The light creates a feeding environment for plankton and baitfish. We used to think that light simply attracted more insects but we now know that it’s more about attracting the plankton and phytoplankton that baitfish feed on. And where you have an abundance of baitfish, your predators are close behind. The more baitfish that are attracted, the more of a “frenzy” is created, luring the larger fish to an area of feeding abundance. This works for both day and night feeders.

The wavelength spectrum of particular colors seem to work best. Just like the color green is easier on our eyes, green seems to work well with fish. Green and white fish lights tend to attract more freshwater fish with the color blue working well in saltwater.

HID fish lights are the most powerful when electrical capability is handy. When an electrical outlet isn’t available for HID lights, there are now new and more powerful LED lights that can be powered off a 12v outlet port or battery from your boat. The best submersible lights offer 360 degree coverage. This should be done from an anchored boat so you have a fixed position. The fish will be attracted to a submersible fish light the way they are naturally attracted to light sources on fixed structures like docks or piers. These lights can be weighted or fixed to the boat with suction cups. More is better. Try two or three lights at once for a larger throw of illumination.

Of course, it’s always important to make sure you choose a location where the fish are. If there are no fish, it makes no difference if the area is lighted or not. It’s still important to know your fishing spot. Too deep, too shallow, or not enough hiding spots for fish and your chances of catching fish will be limited. So check out your spot during the day first.

Go ahead. Become a night fisherman. You may decide you like it better than the daytime and find that your catch is far greater with the use of an underwater fish light.


When comparing LED and HID fish lights, there are many things to consider. Some fish light companies use LED lights for their dock systems. While LED lights are relatively bright compared to typical lights we, as consumers, are used to on a daily basis, they are not always bright enough to light up a large area by your dock. LED lights also do not generate heat; therefore, they are unable to clean themselves. This will lead to excessive aquatic growth, like barnacles and algae, to build up on the light in the water, and eventually render the light useless. To recap, LED lights struggle in two ways; they are not very bright, and they cannot clean themselves.

The best type of light for permanent dock installation are HID lights. These bulbs are not only over 300% brighter than LED lights, they are also self-cleaning. These bulbs generate enough heat to burn off any aquatic growth that tries to grow on the bulbs. Because of this, high-quality fish lights run on a photocell, which turns it on each night and off each morning. This ensures the light will turn on all night, every night, to it can remain clean and barnacle/algae free. The photocell also builds a feeding cycle for the fish, teaching them that each night they can find food by your dock, so they will keep coming back.

It is also important to be wary of the lumens posted on many fish light websites. Some companies claim their 175-watt bulb gives off 22,000 lumens. This is absolutely false. Unfortunately, the tool that is required to measure lumens is incredibly expensive, therefore no customers are able to dispute the claims made by these customers. While comparing fish lights, you must look at the wattage of the light. All 250-watt lights will have 14,500 lumens, and all 175-watt lights will have 9,000 lumens, no matter what the company claims. If you are comparing companies, be sure to look at the individual components they use to build their lights. While some use simple extension cords (which is illegal), other companies will use UL approved underwater-rated wire. Many companies only have a one-year warranty while others have three-year warranties. Do not let claims of high lumens trick you!
