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 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.

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.

Marker lights were exact replacement of original lights, thanks to etrailer Vanessa’s research. Glad I bought spares for on the road needs.

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.

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

These were only direct replacement for the bargman lights on by 1997 trailer. Price was great, delivery fast. Being direct replacement there are no holes to drill. Cut off old connectors and crimp the new ones on. Thanks.

Product was a perfect fit for my 2004 Fleetwood Bounder. I bought 4 running lights. 2 amber and 2 red. works great

They fit our 5th wheel. They are a match for the original lights.

have not installed these REd ones yet; however, the identical Yellow ones I ordered work as described exact OEM for 1998 Tiffin Allegro Class A RV I bought 5-6 of these in yellow as well as red to replace OEM ones that had failed after 22 years, only replaced a few of the front yellow ones, rear red OEM ones are still working. Bulb and space for bulb could be bigger for a brighter illumination as I normally replace all my bulbs with larger/brighter/less juice need LED bulb, but this standard illumination is bright enough.

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.
