Review on Partsam Trailer Flange Diodes Utility by Brian Nelson

They look good and work well so far, only installed about a week ago so time will tell I have a couple of mounting brackets Bought at the same time from Revain so I could replace the old round headlights fairly easily, I was worried about the wiring as the wires on my old trailer headlights were different colors and I'm not an electrician but if you can get the white wire know on the new headlight is the ground wire. I just bolted it to the frame and then connected the two remaining wires to the old wires. The first time I got it right, the second time I just changed the connections and then the other light worked fine so don't worry about the wiring while you ground the white the other two just connect them, forget the colors, If the light doesn't work, swap the connectors, it seems you can't do any harm. It would be nice if the supplier added this information or actual wiring information, but overall I'm happy.
