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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL66RB Review

Here we have Optronics thin-line LED trailer clearance and side marker light, part number MCL66RB. The lens of this light is sealed and waterproofed with the housing. Inside are six LEDs that draw a total of 0.048 amps at 12.8 volts. The light is designed to surface mount using mounting holes that are 3 inches on center. The light is a two wire design, meaning you will have one wire lead for ground and the other wire lead will serve as your power connection. Next we are going to hook up the light to a power supply so you can see how it looks. We will connect the white wire to our ground and the black wire to our power. Next we will turn off the overhead lights so you can see how bright the light is. And that does it for Optronics thin-line LED trailer clearance and side marker light, part number MCL66RB.

These are nice, they are completely sealed from moisture and are more than bright enough. Extra work to change the entire fixture instead of a light bulb but more than worth it.

Nice bright marker light and easy to connect to existing wire harness.

The 2 amber and 2 red lights I purchased are still working just fine. Great lights and I would buy them again.

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.
