Optronics MC66 Series Dual Bulb Marker Clearance Light Dimensions

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MC66RB Review

Today we have Optronics Oval 2 Bulb Trailer Clearance and Side Marker Light part number MC66RB. This light utilizes 2 bulbs for higher light output. Both the bulbs and the lens on this unit are user replaceable. The light is designed to surface mount on your trailer using mounting holes that are 3 inches on center. It utilizes a 2 wire design meaning you will have one wire lead for power and the other wire lead will be for your ground connection. Next we are going to hook the light up to a power supply so you can see how it looks. We will connect our white wire to ground and our black wire to power. Next we will turn off the overhead light so you can see how bright the light is. And that is it for the Optronics Oval 2 Bulb Trailer Clearance and Side Marker Light part number MC66RB.

After working on the old lights on my camper numerous times just prior to leaving on a trip and while traveling, I decided it was time to replace all of the lights. I purchased two new tail/brake lights, and four new side markers. The total price including shipping was just over $28 (I should have done this a long time ago). The lights arrived within 3 days of being ordered, and I was able to install them fairly quickly. I am so happy that I now have all six lights working perfectly, and shouldn't have to worry about them for a long time 16917
