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.

Great product, ordered 3 first time as they claimed to be exact replacements for my older model DP motorhome. They fit perfect right out the box and are very bright, so I ordered more to replace every marker light on the Coach and several more for spares. A great product and couldn't beat the sellers price. 514031

Exact replacement - was expecting just the lens and received the whole light assembly - found out that the lens is glued to the base. Easy replacement - two screws and a couple but splices and tape. The light assembly even has a new rubber gasket glued to the bottom. Great experience with this supplier - shipped quickly and well packaged - very good price also - will recommend to all my friends. 241684

We have a 2007 34' Fleetwood Expedition Diesel Motorhome. We were in need of two replacement lenses and bulbs, as the two modules on the rear of each side of the motorhome were weathered and cracked. We Googled the DOT number and and a match came up under etrailer.com's website, under item number MC48RB. It is a perfect match! Shipping was good and we installed both replacements without any difficulty. Please see the picture of the original 2007 lens and unit and then look at the new one! Thank you for carrying item MC48RB. 696762
