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

This product is easy to install and works great

Great kit. Easy to install and works as it should.

Everything is as described and they look great. Wiring was plenty long, light were bright, and installation was a breeze.

I purchased this product to replace a set of incandescent lights on a small trailer. Both of my tow vehicles have separate turn signal / brake lights, and both have tail light converters. However, only one of them would make the trailer lights work. So I assumed the problem was available electrical power, and thought LEDs could solve it, as LEDs typically consume less power. I ordered this set, and the shipper shipped them very fast. Installed them on the trailer, which was a breeze, other than my choice to cut and solder wires rather than use their wire splice clips, and neurosis for ensuring that the wires are "just right". The only complaint is that the ground lead could be longer, but my trailer folds up, so it requires a longer lead. The light wires themselves were much longer than needed on my little 8' long trailer. I installed the lights, plugged the trailer in to my tow vehicle, and the lights wouldn't work. This was strange, as the LED's should draw LESS power than the original incandescent bulbs. I contacted the seller for advice, but they had nothing to suggest other than double checking my wiring. So I made my own diagnosis. The problem was was voltage. It turns out my non-powered tail light converter dropped the voltage by a little more than 1 volt. 12.2 volts at the battery equaled 11.1 volts out of the converter, which is apparently not enough voltage to excite the LEDs to light. The LEDs draw very little current, but they still require close to 12 volts. I ended up ditching my converter for a Tekonsha 119130 Taillight Converter, which only loses a few millivolts. I was afraid I was going to have to buy a more expensive powered converter, but the Tekonsha unit did the trick. Now these LED's lights work very well. Nice and bright with very fast response. I have not tested their water resistance as of yet, and will most likely never submerge them. But for me, they are (now) a win. I didn't like having to replace my tail light converter, but it was a voltage vampire, so I can't blame the lights.

Easy mounting. After 4 years still working like new. Well worth the money.

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.

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.

Nice light kit! Lights are bright and the wires seem to be thicker than the LED set that I bought at harbor freight a while back. I haven’t submersed them yet but they look like they’ll do fine. One of the light side markers had a crack in it so I contacted CZC direct and they sent me out a replacement ASAP. I received it a day earlier than they told me (next day after I gave them my address). Talk about quick customer service! I tested every light before installing with a 12v drill battery and they all worked great. Easy install and I would recommend. This was for a boat trailer so I didnt use the included wire nuts or the splice clips. I used heat shrink butt connectors and a little liquid electrical tape for extra precaution on all connections including over all the ground connections(after they were installed so to not interfere with connection). I had just repainted the trailer so I had to grind down all of my ground connections points. My only complaint, and it really isn’t that big of a deal, is that I wish the kit came with more of the wire clips the hold it to the trailer frame. I wasn’t planning on using them but they were much easier to use than my self drilling wire clips I had purchased. No big deal though, Amazon has an add-on pack for less than 3 bucks that I’ll be ordering and installing. Overall good product for the price!

These trailer lights are incredibly bright and fully waterproof. Installation was straightforward with clear instructions. As a best practice my neighbour recommended that I run ground wires from the harness to all short ground wires coming from the lights, instead of just counting on continuity through the trailer - I have had these on a swadlo trailer for two seasons and They’ve held up through rain, mud, and highway miles without any issues. Great quality at this price point, exactly what I needed!”

Buena calidad de producto

wiring was some what confusing , but in the long run everything worked out for the better and works well. for the price is a great deal. thank you these lights are great. a very satisified customer.
