Optronics MCL78 Series Identification Light Bar 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 - MCL78RB Review

Today we are going to show you Optronics sealed straight line truck and trailer identification LED light bar, part number MCL78RB. It is lightly sealed and waterproofed, and inside are 3 red LEDs that draw a total .022 amps at 12.8 volts. It is designed to surface mount on your truck or trailer using two mounting holes that are 16 1/16 inches on center.

It is a two wire design meaning you will have one wire for your power connection, and another wire for your ground. Next we willll hook up the light to a power supply so you can see what it looks like when lit up. We willll connect the white wire to our green terminal for our ground, and the black wire to our power. Next we will shut off the overhead lights so you can see how bright it is in the dark. And that is it for Optronics sealed straight line truck and trailer identification light bar with red lens, part number MCL78RB

Product quality appears excellent. I chose this one because it was LED, sealed, and because the spacing between the bolt holes matched the holes in my trailer from the old light housing. I had to enlarge the center hole a bit to allow the ground connector to pass through but that was easy enough with a stepped bit. I was able to remove the old light, clean up the metal frame and bolt this one right in place. I was about to drill another hole for the ground wire's ring terminal when I realized that it was long enough to connect to one of the bolts. That is probably obvious to many but I almost missed it. One minor complaint was that the holes for the mounting bolts were really small. I was able to find a pair of tiny bolts in my junk drawer that fit but they are REALLY small. I think this would be better if the holes were a bit larger. 607929

I guess it’s ok for a center clearance light. It’ll do the job, i suppose. Guess I didn’t see the part in the title where it said that it was only a 3 diode. I figured there’d be an LED behind each circle on the front of the light but there’s not. For over 20 bucks, you’d think there would be. 494225

The 3 LEDs is kind of lame considering the light housing appears to be made for 11 LEDs. It does work, and has worked for over a year. It is acceptable considering how inexpensive it is. 417559

I have placed 2 orders with etrailer. Both orders were for trailer lights. The videos explaining the operation of the lights were very helpful.
