Review on Partsam 4x LED Boat Truck Trailer Marker Lights: Front Rear Side Indicator, Amber/Red, 4 inch Rectangular, RV/Camper Clearance Lights, Waterproof, 12V by Paul Opoku

Installed these on my Trillium Camper to replace my old plastic based white side marker lights that were faded and cracked. They come with 2 mounting screws (good for mounting in wood, fiberglass or lightweight plastic). Be sure to use correct polarity when connecting as they are LED and will only work if you connect them with correct polarity. They seemed bright enough to be used as side marker lights, and the LEDs and circuit board are all encased in clear epoxy, making them waterproof if some water gets under the lens.
