C.E. Smith Post Guide-On Led Light Kit - These tough long lasting, waterproof, shockproof LED post guide lamps make it easy to see your trailer's position when backing down the ramp and dramatically increase your trailers visibility over the road at night. These lights are easily installed; they screw onto the top of your guideposts and wire into your trailer's tail lights. LEDs are long-lasting, energy efficient and more durable than incandescent light. Features: One piece lamps fit easily on top of your existing 2in PVC post guide-ons. Amber light faces front, red faces rear. (When not energized, lamps appear clear) Includes two sealed one piece LED lamps, each with 8ft of wire and all necessary electrical connectors and mounting hardware.
