Review on 2-Pack Amber LED Side Marker Lights for Trucks and Trailers - Sealed, Waterproof, and Surface-Mounted Indicators with 3 LEDs, Front and Rear Compatibility, and 3.9-inch Size by Partsam by Thasapon Bowers

Product as advertised, reasonably priced and fit for intended use. Upgraded my trailer with side marker lights for more traffic safety + visibility for night driving. We're also hoping to see more potential obstacles and avoid damage when driving with a trailer at night. Improves the appearance of the trailer. Relatively easy/straightforward installation - even for me as a novice mechanic. There were no instructions included. Drill the holes, thread the cables through the frame, attach the base plate with the screws provided (but I used rivets which I think held them in place better), snap the lens cap on, thread the Wires to side marker circuits and ground. Nothing too complicated or I would ruin everything. Basically thumbs up.
