Equipped with two 4-In diameter magnetic mounted LED tow lights, you're provided with stop, tail, and turn signals for a towed vehicle, offering temporary illumination when the vehicle's own lights are obscured or non-functional during towing. Featuring heavy-duty magnetic bases for quick and secure attachment, as well as a 20-ft harness with 4-flat connectors for effortless setup, these lights are designed for cars and trailers no wider than 80-In. Additionally, their sonically sealed, waterproof housing and lens unit ensure durability and reliability in various weather conditions.
