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 Bargman Trailer Lights - Clearance Lights - 40-40-104 Review

Today we're gonna take a look at the Bargman fender clearane side marker light with the amber and red lens. Now this is a combination side marker light and clearance light that'll install on your trailer fender. Has an amber and a red lens, you can see combined here. Does use a sealed incandescent bulb. It is a two wire design. Has a power wire, which is the brown wire and the white wire, which is your ground and the wire length on this extended all the way out gets you about 24 inches long. Give you a few measurements on this light.

The overall length from this end to this end is right a two-and-three-quarter inches. The overall height that's installed is about one inch tall and then the depth'll go anywheres from about a-half-an-inch at the end there and then towards the middle goes all the way to about an inch. So what I'm gonna do is go ahead and hook this up to a 12 volt power just to show you the light so we'll go ahead and hook the white up to the ground and we'll go ahead and hook the . and there we'll go ahead and turn off our overhead lights and you can see how bright it is and, depending on which side you look at, you can see this way it'll be the amber with the light in the middle and this way it'll be the red and turn on our overhead lights and turn off our . power but that should do it for the review on the Bargman fender clearance side marker light with the amber and red lens.
