These 12V DC 8 inch Oval trailer lights are universal for rv, motorhome, camper, Trucks, trailers, tractors, semi trailer, horse trailer, travel trailer, dump Truck, special vehicle etc

lights are HARDWIRED with 3 wires: White is Ground, Red is oval stop brake light or oval turn signal light and Black is oval tail/running light; They're surface mount with 2 holes to secure and you'd need a hole for the wires to go through as there's no room under the red tail lights. Also a mounting gasket goes in between the light and the mounting surface, which creates a tight seal and offers some cushion behind the actual light;

.

One light was wired before I realized the light itself was not the issue so one mounting gasket is used while other is new.

Both lights are new
