These High-Intensity LED Underwater Lights are totally waterproof and designed to be used above or below the water line. These lights are great for illuminating your boat's surroundings, transforming your interior for a unique look, or even for attracting bait fish to your boat. A broad flood light effect is created by the engineered optics of the convex light face. Compared to other LED models on the market, this light has a greater light output and a wider aperture.

I purchased two of the T-H Marine LED Underwater Boat Lights, and while one of them stopped working within the first month, the company’s customer service really impressed me. I reached out, and they responded quickly and sent a replacement right away—no hassle at all.The lights themselves look great on the boat, and knowing the company stands behind their product makes a big difference. I’d definitely order from them again just based on how well they handled the issue. Great experience overall!

These lights were originally installed on my Key West boat and had stopped working so I bought the same lights to replace the original. They are cheaply made and don’t last. I wish I had spent the money on better lights.

UPDATE: After about 3 months after the installation, the saltwater has eaten through the seal where the glass connects to the to the back of the light. It started taking in water and quit working. Wouldn’t recommend these lights especially on a salt water.This is a light that you definitely get what you pay for. It’s much cheaper than other transom lights for a reason. Like everyone else in the reviews say: this light will crack very easy on installation. I knew this going into it and still cracked 2 of them. Any amount of pressure on the light from the screw will crack it instantly and it will take in water. The second takeaway is don’t expect much brightness. It only lights up between 2-3 feet behind my boat and the ocean water where I live is pretty clear. At night when pulling up to restaurants, there’s a huge difference between the more expensive lights and the $40 lights.Side note: I didn’t take these pics. They were edited before they were sent to me, so they appear to be much brighter than they really are.

I installed 2 lights less than a month ago and they are both full of water. 1 stopped working and I expect the other will do the same very soon. These are not waterproof lights.

I installed three of these units under my boat swimgrid, above the water, and they emit more light than many underwater lights - although these are waterproof too. I decided to mount on the boat transom and point down towards the water. After comparing with a friends $3,000 lighting system, mine was warmer and brighter, and he couldn't even tell that I had mounted above the waterline. He has already had problems with his submerged lights, and me, no problems after two years. The blue light is very attractive, and gives my yacht an entire new look at night.

As a tournament fisherman we, and 500 other boats head out before sunrise. Navigation lights alone dont feel like enough to prevent crashes, but I cannot bring myself to run the big deck lights with so many boaters navigating in the dark (wish others felt that way) and so these lights add safety, functionality and a cool factor. I highly recommend them. Very easy to install and wire.

ok first of all i hate to leave bad reviews but this was unreal, the first pair i bought for my 20 ft boat i installed on a warm winter day with 5200 as they are below the water line. I tested them they worked and i was happy, the weren't that bright but for the money i figured i only needed a little light. Came out to do some other work on the boat about a week later and noticed one had water in it. The boat is on a trailer and hasn't been in the water as its winter in NJ. So i checked the light and here i must have tightened it too much as it cracked. So i figured my mistake even though i didn't crank down on them that hard. I figured i would order another pair and take my time and not over tighten. So removed them and the 5200 and cleaned everything up, tested the new lights to make sure they worked and put them on. I did not hook the wiring right away as i had other things going on and wanted the 5200 to dry anyway. Two days later i go out and hook all the wiring, make it all nice and neat wire tie everything up and flick the switch...... only one lights up.... try to to flip out maybe i missed something, cut the connections and hooked that one up direct to the power and ground... nothing.. So now i have to re install, clean the 5200 and start the process all over again.. Spend the extra money to get something else, you will be happier.

These lights are Kick-Ass. We were at Marauder charters in Solomons Island Maryland. We have installed the green ones under water to attract the fish and one set of switches. We also set the blue color lights above the waterline and in cockpit cabinet lighting over the stern. Extremely satisfied with the performance of this product and its ease of installation. I tried several other products underwater lights on my smaller 23 ft boat before choosing this brand after a two year trial on the smaller boat we installed hem on the 44ft charter boat. Come fish with us !!

We mounted this on the bottom of our hovercraft to make the water blue.It is easy to install, is quite bright and is sealed against water.It allows flush mounting (with the hold directly behind) or has a spaces to the cord can be run up to another penetration point.We run it off of a AA battery pack and it works great.We liked it so well we purchased a white one to use as a front light .It works exactly as we hoped.
