P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.


Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

  • Is the optronics LED Trailer Clearance Light MCL55RB a Reflector
    Hey Rex, the Optronics LED Trailer Clearance or Side Marker Light # MCL55RB is not a reflector unfortunately. If you needed a reflector you'd want to use the Optronics LED Clearance or Side Marker Trailer Light w/ Reflector # MCL0040RBB. This light is a bit wider than # MCL55RB but it does have that built in reflector. This light also does not have the industry standard two prong plug but it can easily be wired into any 12v system with its two wire configuration. If there is anything...

  • 2-1/2 Inch Diamter Clearance Lights For Camper
    SAE is not actually a part number, it just means it passed a safety test for Society of Automotive Engineers, which is likely why you were having trouble finding it. We have a plethora of 2-1/2 inch dimeter clearance lights, depending on if you need red or amber: - Red: Optronics LED Clearance or Side Marker Trailer Light # MCL0040RBB - Amber: Optronics LED Clearance or Side Marker Trailer Light # MCL0040ABB
