Glowing Reviews: The 6 Best Underwater Dock Lights for Fish and Ambiance

Do you use underwater dock lighting on your boat dock? If not, maybe you should give them a try. 

Underwater dock lights can not only be used as submersible fishing lights to attract bait fish and catch bigger fish, but they also bring in a bit of outdoor ambiance. They can even come in handy on a kayak or a liveaboard boat.

Let's go over some of the fun and useful aspects of the best underwater dock lights.

Where to Use Underwater Dock Lights

While underwater dock lighting is made for docks and fish-finding, it can certainly come in handy in other fresh and saltwater situations.
  • Pontoon and Boat Bottoms: Attach to the sides of your pontoon or deck boat to add a festive touch for on-water parties and entertaining.
  • Ponds: A fish pond or bigger body of water can easily be decked out with underwater lights to create a fun, and safe, look.
  • Pools: Underwater dock lights can bring atmosphere to any pool party.

Purpose of Underwater Dock Lights

Yes, manufacturers of underwater dock lighting and submersible fishing lights extol their fish-catching virtues. But there are bunches of uses for these aquatic assistants other than fish and bait. Of course, that is the biggest use, so we'll catch that one first.
  • Finding Fish and Bait: The light attracts bait fish such as shad and minnows. The presence of the bait fish is followed by trout, bass or flounder that are there to eat the bait. Sort of a mini seafood buffet for the bigger fish. Whether you're trying to catch bait to go out fishing, or just fishing from the dock, underwater dock lights can act as submersible fishing lights and give a helping hand.
  • Viewing Fish:  So you're not into fishing. Not to worry. Underwater dock lights are a great way to see just what's under the water. No poles or worms required. You'll have your very own aquarium.
  • Entertainment and Decoration:  You can use underwater dock lights to decorate a pool or lakefront area for special occasions or just because it's Tuesday.
  • Safety Factors:  Safety comes first around the water. Use underwater dock lights to alert walkers that there's a dock (and hence, water) in the area. This can be very helpful when it's dark and guests are unaware of their surroundings. When kids are around, it really comes in handy.
  • Navigation and Visibility for Night Boating:  If you're going out for night fishing or star gazing, having a well-lit boarding area is a must.

Features of Underwater Dock Lights


It goes without saying that underwater dock lights need to be waterproof. The more durable the better. You'll want to look for stainless steel, PVC coating, high-rated LEDs with protective layers and other marine-grade components.

Floating or Sinking

Underwater dock lighting comes in floating or sinking versions. With the sinking variety, simply plug in and toss in the water. The floating variety is much the same. It just floats instead of sinking.

Types of Lights

High-Intensity Discharge (HID) Lights are a lot brighter than LEDs. They also generate heat to prevent barnacle growth on the lights. They're usually encased in a covering, which can diminish the light output.

Light-Emitting Diodes (LEDs) are more efficient than other types, but they don't generate heat. This means that they don't clean barnacles and algae off on their own. You'll have to spend time every once in a while with a scraper or scrub brush or risk damage to the light.

They make a great choice for temporary use or for somewhere you won't be leaving them underwater for prolonged periods of time.

Light Color

Green and white lights are the most common colors found on underwater dock lights. Green travels through the water better, and for further distances, than blue. Green also doesn't produce as much glare as blue light.

White light is brighter above the water, but it does have a tendency to attract bugs, which you may or may not want.

Blue lights work well in saltwater, but it's not as great at attracting fish in freshwater. It's often used for decorative, or mood lighting, purposes. I love the look of a blue light in a waterfall feature.
