Optronics MC48 Series Red Marker Clearance Light with Reflex Dimensions

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.

Excellent replacement for my old original 2003 Tiffin Allegro Motorhome that came with the T. Bargman 68 SAE-P2-A-81 clearance lights. The new MC48RB used the same mounting holes and had about 5" leads coming off the light to make wiring easy. The new light is slightly brighter looking probably do to the old ones being weathered. 883768
