Review on Blazer C7280 LED Trailer Light Kit - Low Profile & Submersible for Superior Performance by Bruce Marable

Quality kit with everything you need in the box. If you plan on getting wet, use heat shrink connectors and apply sealant/glue where the wires enter the lenses on the back. Very bright to alert other drivers. This is a 4 pin set. The wiring harness requires an additional 18 inches of length, but will work as is. I had to add nearly 2 feet of wire to this harness for it to reach the truck. If you're using a bumper mounted ball you might be fine, but expect an increase in length. Check these lights before installing them. I had two driver's side side lights with faulty circuit boards causing some functions to be much dimmer or blink oddly. I will also be caulking the headlights where the wires go through the housing as they are not caulked and water will likely seep in.
