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.

We have ordered from etrailer twice, both times were a great experience, orders were shipped fast, this last order was for clearance lights for the rear of our Motor Home, fit was perfect. Thanks 316968

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

The price really sucks. I bought the same lens from you for less than $2 bucks in the Amber color, and the stupid red one was over $5 bucks. That is absolutely crazy to me. Can you explain that to me where it would make any sense. 766539

The lights purchased were to replace the 5 or 6 night lights at the top rear edge of our Chinook Premier motorhome. They came with wires securely attached and were installed by our mechanic. They mounted flush onto the fiberglass surface of the coach and did the trick. 757243

I love etrailer! I'm a Service Manager at an RV repair facility and I come across some old units with obscure lights, latches, etc. and etrailer normally has what I need. Even my wholesale distributors don't have this stuff! Thanks, guys. Keep up the good work. 739838
