Optronics MCL66 Series LED Clearance Marker Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.


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.

It would be difficult , if not impossible, to have a more helpful person facilitating the placing of an order than Paula at etrailer. I swapped out all incandescent light fixtures on my trailer with led, and the buyiing/ selection process was made a pleasure with her help. 488156

I bought these to replace all the old ones on a camper re-fit. I bought both Amber and Red. I replaced the entire fixture and it was worth the effort. These are very bright and moisture proof so they don't get bad connections. I soldered the wires into the wiring though. 363447


Comments
Very nice, being waterproof and they are more than bright enough also. It was a good investment compared to the standard bulb kind that were on the camper by far.

Nice an bright. Holes lined up perfectly for my 2000 EZ Loader trailer and Skeeter. Only downside was that overall the light was slightly shorter than the OEM light which meant I had a hole to plug. 150783

These lights worked really nice fitting in to the corner openings on my Pace trailer. I love the fact that they are LED and don't pull much if any battery load. 131801
