CZC AUTO 12V LED Submersible Trailer Tail Light Kit Stop Tail Turn Signal Lights for Under 80 Inch Boat Trailer Truck RV Marine

Easy installation and lights are bright. Works great

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.

Exactly what I needed, works great, easy to install, great price

Although clearly built to a price-point, I have nothing real negative to say about these light. Yet! Install was mostly easy. The side marker lights were not standard (compared to other sets I have installed), requiring me to make mounting brackets for them, which was not hard.A couple quibbles, none bad enough to take points off.The included wire was crazy thin. Acceptable, but thin. It is doing the job now. The included wiring hardware is laughably bad. Use your own waterproof terminals to connect the lights to the wires, if you want any kind of reliability.As mentioned, the install was uneventful. Easy as it comes. Take your time, make good connections, properly run the wire, Use some anti-seize on the nuts and bolts to aid in future service. The lights themselves were more than bright enough. They look pretty good actually. Survived being dunked in the ocean as well.Time will tell how they work out. I have not had good luck with inexpensive LED lights lately. Maybe this will be the outlier. As I mentioned, the initial impression is very good, They look good and work well.
