Review on Round LED Trailer Tail Lights Exterior Accessories by Ricky Pee

Except no plug they work after I got the plug adapter with cables don't know why they don't include or offer this option. I believe there are cases when the adapter is already used in modern light sources. I soldered the wires to the existing trailer lighting wires. The 5.5" three-hole/screw mount was just what I needed and it fitted perfectly into the trailer's existing light hole. The LEDs look very bright even in daylight, I hope they last a long time.
