Nice bright led lights and side lamps. Installation was easy and all connectors were included. There was enough wire for my 10’ long trailer, with extra wire length to fit a 16’ trailer, easily. Don’t anticipate to submerge the lights but the look pretty solid and waterproof. The are a bit light in weight so I’m sure and kind of impact may crack the housing. However, so far so good. They look good and work as they should. Great trailer light for the price!

I just installed these on my trailer and they work great. Great value. Lights come with all of the required hardware to install. The only downfall I ran into is the side marker lights came with different mounting hardware than what my trailer has, so I wasn’t able install them. The side lights come with 2 wood screws to attach to the trailer, which do not work on a metal trailer.

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.

I use a 4x8 trailer to haul kayaks, a 4-wheeler, lawn tractor, lumber, and motorcycles. I don't submerge it when launching the kayaks, so I won't evaluate the water-worthiness of the lights. Today I rewired my trailer. The total time from start (readying the materials) to finish (putting things away) was 90 minutes at a steady, unrushed, pace.After placing the trainer on it's side and removing the old lights, I used the old wiring to pull the new wiring harness through the frame-mounted (undercarriage) conduit. I then wire-brushed, filed, and sanded the metal surface where the ground leads to the tail lights would be attached to the frame. Each light was grounded to the frame using self-tapping screws. Dielectric grease was applied to the cleaned/sanded grounding surface to help promote electrical conductivity.I agree that the crimp-on terminal for the ground (at the end of the tongue) was rather light-weight, but I used it. It works. I did trim away a small amount of insulation and crimped it directly to the bare wire instead of to the insulation, not depending on the crimps to puncture the insulation for contact. Since there's no stress placed on this connection, I felt safe using the provided terminal. Again - metal was cleaned, dielectric grease and self-tapping screws were used for that grounding connection.I have an F150. The vehicle-mounted flat-4 connector is female. The included wiring harness connector didn't match it until I used a sharp knife to trim away that connection's "boot", thereby exposing three male connectors. The fourth connector (green wire) was carefully shaved, reducing the outside dimensions slightly, until it snugly fit inside the shaped receptacle mounted to the vehicle. Next, each of the three male connections was increased in diameter to facilitate a secure connection, by slightly spreading apart each pin with the blade of a pocket knife. A pre-existing slot in each connection made this an easy task. The lights were soldered to the harness, then wrapped in electrical tape and zip-tied out of the way to avoid snagging the wires. Plastic ribbed sheathing (from the old wiring) was applied to the new wiring harness where it emerges from the tongue and taped closed on each end to discourage ants and spiders from nesting inside.Dielectric grease was applied to the male flat-4 connector pins on the trailer, and to the female flat-4 connection on the vehicle. The trailer was mounted to the hitch, wiring harness plugged in, and lights were tested. All lights functioned perfectly and were very bright - a huge improvement over the incandescent lights that were replaced!If I decide to immerse the trailer for boat-launching, I'll waterproof the lenses and housing with silicone caulk. As a precaution, I'll unplug the harness from the vehicle. However, kayaks are easy to carry to the water's edge and launch without a trailer.All said I'm very happy with my purchase and with the function of this replacement kit. The only thing left to do is put the trailer and lights to use and see how the lights hold up. If today's experience is any indication, I believe my optimism will hold.Suggestion for updates: Replace the lightweight terminal ring with one that is more robust. Really want to sweeten your product? Include a small packet of electrical grease.

mounting is easy, they are bright and work good. good deal for the price.

These lights are great. Don't get me wrong. Very well made.But. Because these are LED lights, my Tesla Model Y wouldn't recognize there were lights attached and wouldn't send any power to them. Lots of cars nowadays have computers that won't recognize LED trailer lights. They need to have a small resistance, and the LED's don't. The computer in many modern cars sends out a small voltage to 'test' to see if lights are present, or more importantly, if there's a short. In which case it won't send the full 12V because it would blow a fuse. LED's don't conduct electricity until the voltage exceeds their 'forward voltage' - usually around 2-3V - and the 'test' voltage may be lower than this. If the LED lights have many LED's in series, then that required forward voltage may be much higher.So, the solution is you may need to purchase a different 7 pin to 4 pin adapter that has the resistors built in. There are several available on Amazon. Search for "7 to 4 pin trailer adapter LED".Or, you can add your own 150 ohm resistors between each brake light to ground and the tail lights to ground - you'll need 3 resistors and they'll need to be large ones - minimum 1 watt (1W) resistors to handle the 12V that's eventually going to be sent to them.You can see how they are connected in the attached pictures. White is ground in trailer lighting. So one resistor from yellow-white, green-white and brown-white. You could do this inside your 7 pin adapter as in the pictures, or you could just do it between the wires on your 4 pin connector, directly on your trailer. Either way will work and will make these lights recognizable by fancy, modern, smart automobile computers.

Buena calidad de producto

nice outloock, I have atached magnet's so it is remoovable.

Came with everything I need to fully wire a trailer at a reasonable price. The lights are nice and bright. I hope they last.

Great value very adaptable and versatile. Easy install.
