Optronics MCL97 Series LED Identification Light Bar Diagram

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 of each light 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 or P3-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated or P3-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.

Pless - 07/07/2020



I received my LED lights for my trailer today from etrailer .com. Shipping was very fast. They bolted right up to the old holed that are on the trailer. Installation was very easy. I like the features of LED lighting. They take less electricity and are much brighter than conventional lighting. I know they will be much safer and look better than the old lights I had on it. 661154

Ask the Experts about this Optronics Trailer Lights

  • Difference Between the MCL97RB and MCL97RPG Optronics Identification Light Bars
    Yes, the only difference between these light bars is that the # MCL97RPG has the 0.180 male bullet at the end of the wire and the # MCL97RB just has a regular wire you'd use a butt connector like part # DW05744-5 for the installation. Other than that everything else is the same. I have attached review videos and photos for you to reference the differences as well.

  • How To Hook Up the Identification Light Bar MCL97RB To a Two Wire Plug
    I am not familiar with the two wire plug set on your ShoreLand'r Boat Trailer but the Identification Light Bar part # MCL97RB only has one wire which will need to be connected to the running light circuit (usually brown wire) on your trailer with a quick splice connector part # SWC501746-1. The ground for the light is integrated into the base which is why there is not a separate wire for this. If the two wire plug you are referencing has a wire for the running light circuit and one for...

  • How Does the Sealed, 3-Light Truck, Trailer Identification LED Light Bar MCL97RB Ground
    The lightbar part # MCL97RB that you referenced does ground through the mounting hardware. If one of the wires on your trailer's currently lighting is for the ground you could run it to the mounting hardware of the light or you could not use it. If you check out the review video I attached you can see our demo guy run the white ground pin straight to the metal frame of the light to ground it. If where you want to install this light bar is a metal surface that touches the frame of the...

  • Can Sealed, 3-Light Truck Trailer Identification LED Light Bar # MCL97RB be Mounted Horizontally
    I spoke with my contact at Optronics and yes, the Sealed, 3-Light Truck, Trailer Identification LED Light Bar, # MCL97RB, can be mounted on the roof of your horse trailer. When mounted horizontally, the light will be visible from the rear of the trailer but won't be at the same intensity as if it was mounted on the rear of the trailer facing back. Please keep in mind that since the intensity of the light will be decreased when mounted on the roof, it will not meet DOT regulations.

  • Information About Optronics Sealed 3-Light Identification LED Light Bar

You have one wire that is attached to your power source. The mounting holes are spaced 8-1/2 inches on center. I have attached a product review video you can check out that explains this in the demonstration.

  • Single Wire ID Light Bar for a Boat Trailer Over 80 Inches Wide
    Your old ID bar must have grounded through its mounting hardware since it only had the one wire. ID bar # MCL97RB also has just one wire and grounds through the mounting hardware. This is an LED light so it will draw much less power than incandescent lights. If your boat trailer is aluminum though a jumper ground wire should be attached between the frame and mounting hardware and attached to a steel surface or the main trailer connector ground. A ground issue is why the other light was...

  • Converting Trailer Light Bar from Incandescent to LED Lights
    The code SAE P2 91 DOT on the light lens is the lens rating, not a part number, so it is difficult to go by that number. Often the actual part number for a light will be on the back of the light base or housing. If not, it is usually easiest to go by the dimensions of the light when choosing a replacement like the LED-type # AL191RB. We do offer complete 3-light LED light bars, such as parts # MCL93RB and # MCL97RB, which appear on the linked page with other trailer clearance lights. You...
