CZC AUTO 12V Submersible LED Trailer Tail Light Kit for Under 80 Inch Boat Utility Waterproof (Trailer light kit)

Nice light kit for the price. Everything you need.

Perfect for my little boat trailer I built. Easy to install and hook up, lights are normal trailer light quality. LED’s look much better and brighter compared to old school light bulbs.About half the price compared to buying same kit at a local brick and mortar store.

These worked perfectly for my cable project. Worrying then was a breeze. Lights are super bright.

The lights are working good for about 3 or 4 years now. I had to replace the wire though, it was low quality and didn't last.

Perfect fit; nice and bright. The instructions could be more clear. The instructions also say that the lock washers and license plate mount are not included, but they were included in the box. Very happy with this product. A very good value for the price.

Good lighting kit for boat trailer. Great instructions with kit.

I tested the lights with a 12v battery and all seemed good. So, I set to mounting all of the lights and loosely hooking them up. When I went to test them, they were not working correctly. The red side marker light on the tail lights was working but tail lights were not (maybe very dimly) but no blinkers. I tested the wires all the way to the light hookup and was getting power so I could not figure it out. When I disconnected one of the lights, it seemed like the other light worked mostly. I switched wires between the two lights and had the same results. I was pulling my hair out and finally for some reason checked the while ground wire to the trailer. I had clamped it to the trailer frame with a vice grip. I moved it and touched it to a nice clean bolt and bam, lights came on nice and bright and correctly. I spent a good hour moving wires around on the lights and testing all the different light functions and it all just turned out to be a bad ground. If they wouldn't have worked at all, I would have given the ground my first attention, but since it was just a "bad" ground, I guess the lights partially/kinda worked which threw me off. So, tomorrow my shrink tubing arrives and I will be able to permanently run the wires and hook everything up properly. I had a set of LED's before these and they worked a lot better than the old style incandecent, but several of the LEDs on one side were out. Also, one of the amber (incandescent) side marker lights was going bad and they were wired in series so if the bulb on one of those went out or the fixture was toast, it would cut off power to the tail light on that side. This set will be wired in parallel so that won't happen again and these side markers are LED so chances of the bulbs dying a much lower too. Automotive wiring always seems to throw a curve ball to me, so I hope this is the last time I have to deal with faulty lights on the trailer. AGAIN, MAKE SURE YOU HAVE A GOOD GROUND ON THE TRAILER.As far as the review goes, I am not going to blame the lights. It wasn't their fault but these lights look like a quality set and clear upgrade to my old LED's. Time will tell however. For now, I give them 5/5.

Decent kit overall, but a couple things to know. None if it is really bad, just trying to help the next person out with their project. 1) The crimp connectors for the side lights are not that great, not waterproof and would not last in a boat trailer. 2) The ground is thru your trailer frame. In my case my trailer was bolted together from several segments and there was no ground and I had to make ground connections between the segments. This would also be the case for a tilt trailer. 3) The taillights wires had nice ground connectors on them, but the side lights and main harness were bare so you have to make your own connections. Just installed so no idea about lifespan.
