Optronics MC57 Series Marker Clearance 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.

I have a flat bed on my truck and it uses trailer lights in it. When I looked for replacements all the stores wanted $10 to $30 a peace!!! Etrailer saved me almost $100 over going to may local store. I ordered it on sunday night. I had 2 personal emails telling me my order was ready and being shipped. ON SUNDAY NIGHT!!! I had my order by Wednesday with a follow up email telling me my package was waiting for me at home. My only complaint is why other online stores can provide this service. etrailer, I will be ordering again. Thank You

The lights are fine but the 2 1/2" grommets are too small for PJ trailers. Had to reuse the old ones.



- MC57RB
by:

Equal to or better than the same lights available locally, but at half to 1/3 of the local prices. Even paying shipping I save a lot. Delivery with E-Trailer is always timely, too.
