Today we are going to show you Optronics Double Bulls Eye Trailer Clearance and Side Marker Light, part number MC42RB. Inside the light are two light bulbs for increased light output. It's a single wire design meaning we'll have a single power wire lead, and the light will ground electrically through the hardware used to mount it on the trailer. Both the bulbs and the lens are user replaceable. It's designed to surface mount on your trailer using the mounting holes that are three inches on center.
Next we are going to hook the light up to a power supply so you can see what it looks like when lit up. We'll connect our ground to the mounting hardware, and our power to the wire. Next we'll turn off the overhead lights so you can see what it looks like in the dark. And that's it for Optronics Double Bulls Eye Trailer Clearance and Side Marker Light, part number MC42RB.
