Review on 💡 Partsam 2PCS 4" Waterproof Backup Reverse Light - Flange Mount, 12 LED for Truck Trailer RV - White by Joshua Garris

I replaced the old nasty lightbulbs on my RV with these LEDs. You look great. They're a lot brighter than the old headlights and you don't have to worry about corrosion in the bulb sockets like I did. They were very easy to install. Note that these reverse lights have 3 wires coming out from behind. Red, black and white. I connected white to ground and red to power. They are wired in the same way as tail/brake/indicators. Both the black and red wire will work for the power wire. The black wire is darker, as are the taillights. The red wire is a brighter setting, like brake lights and turn signals. You will most likely want to connect the power supply to the red wire. It's lighter. I am very happy with them and hope they last a long time. Reasonable price.
