    8pc 2.5" Amber + Red Round Trailer LED Clearance Marker Lights [DOT Approved] [Reflector Lens] [Grommet] [Flush-Mount] [Waterproof IP67] Marker Clearance Lights for Trailer Truck (2425)

      ULTRA REFLECTIVE POLYCARBONATE LENS - The 2.5" round LED side markers uses a specially designed polycarbonate lens to reflect back direct light, allowing your tractor or trailer to be more visible at night and providing a safer driving experience for you and other drivers on the road. The round LED side markers also come with a “TOP” orientation, designed to allow you to uniformly install multiple units, while maximizing the amount of reflectiveness from each lens.

      2 IN 1 FUNCTIONALITY - Driving a tractor, trailer, truck, or any other large vehicle mandates that you drive with side marker lights and reflectors depending on the size of your vehicle. The LED clearance lights come with 13 high powered LEDs each, allowing it to serve as both a reflector and clearance light that federal law requires for larger trailers.  These LED clearance lights are also D.O.T. FMVSS-108 compliant.

      WATERPROOF, SUBMERSION READY - The waterproof IP67 rated LED side markers are capable of being submersed. This makes the clearance light ideal for boat trailers that launch and pick up watercraft into the water.

      EASY INSTALLATION - The red and amber lights come with a rubber grommet so you never have to mess around with screws. Simply use a preexisting hole, or create a new cut out for the grommet, and use the industry standard two prong plug to light up the night.

      HIGH QUALITY COMPONENTS - Each 2.5" round LED clearance light uses high quality components made in Taiwan, and is reverse polarity protected, meaning that plugging it in the wrong way will not damage the unit itself. The clearance light has been certified safe by the D.O.T. and comes with D.O.T. SAE certification printed directly on the unit itself.
