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.

14-1/4" Long x 1-3/16" tall x 1-5/16 deep. Waterproof identification light bar with 3 replaceable red 3-LED lights is designed for trailers wider than 80". Polycarbonate lens and stainless steel base. Surface mount. Single-wire design.


Once I had this installed, these lights have worked perfectly. Switching to LEDs and having them properly installed has significantly reduce my trailer light headaches. Definitely recommend this product.


All items are as they are advertised. Arrived within the timeframe stated. They have stuff others do not carry. etrailer is good to deal with, and they make things good which fall through the cracks, as things sometimes do. Wrong part or whatever.


The only issue I had was the size of the box as compared to the size of the product was ridiculous. The box was 10 times wider than the product but needed to be about a half inch longer. Whoever packed it had to force it into the box. It was not damaged and worked just fine. On the positive side your videos and description help me make the right decision on the replacement part.

Working well. Drove to Canada and back. No issues.

This was a great product to replace the old light that usually had at least one of the 3 bulbs not working because of a bad connection in the socket due to corrosion. The mounting holes even lined up so I did not have to drill new holes and the pig tale wire was plenty long enough to make installation a snap.


Very bright and looks good.


Easy to install. As expected. Bright. Mounting holes lined up.



Still working in an excellent manner.


This light is easy to install with only 1 wire and 2 bolts, and it looks great!


Great light works great and very bright.


Works like a charm and much brighter than original incandescent lights.


Thanks for this 1 year review opportunity. My purchased was changing all my boat trailer lights to LED. They are working excellently with no problems. I think they are better than what I see on newer boat trailers. Thanks for your excellence advice, service and prompt shipping.

My LED lights continue to work perfectly. Cant say that for everything on the trailer. But the lights are GREAT!
John G - 09/14/2020


Fit perfectly on my boat trailer in place of the original incadecent lights. They are nice and bright.only difference is this light grounds through the frame instead of a separate wire. Best part-time more bulb issues!

They are great! No problems, Id buy them again. Thanks for the follow up!

Nice looking light bar. Provides the finishing touch on my 2000 Magic Tilt trailer restore! Great service from etrailer folks!


Fits perfect. Nice and bright


Great light, this completes the rewiring and replacement if the old incandescent lights.

The light I purchased are working out great. Last summer while driving through Utah a State Trooper pulled along side of me when I pulled into a rest stop.He asked where I purchased the LED light set and I told him. He knew my trailer was a 2000 and he had a 2001, and was tires or replacing the old incandescent lights.Next I would like to update the lights on my 2006 GMC 34 T truck.
tom d - 08/20/2014


The lights arrived and the installation was very easy, most of the lights i ordered we're plug and play. The LED lights make a big difference on seeing the trailer at night


L E D trailer lights from e trailer are great, they are much brighter than regular lights . e trailer is great to deal with, fast shipping

All lights still working great, love them
nelson k - 04/25/2015


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.


I've installed and hooked up power to these lights and they appear to be of very good quality. They're made in Taiwan which, in my opinion, is way better than china made stuff. These lights look very nice and are bright. I'll have to dunk the jetski trailer in water to see if the lights survive but I'm very optimistic!


Easy to order, delivered on time, easy to install


Works as advertised


These lights went on my boat trailer, been submerged many times w no leaks. Good product!


It has been less than one year and two out of the three lights on this light bar have gone out. I'm pretty disappointed in the fact I replaced my whole trailer with submersible LED lights so this would not keep happening and here we are again.


Perfectly fit to replace the old light bar on my 2004 Aluma. Nice and bright as well.


I bought this to replace incandescent lights on my boat trailer. One of the old lights had burned out. Works well so far.

  • Information About Optronics Sealed 3-Light Identification LED Light Bar
    The Sealed, 3-Light Identification LED Light Bar, part # MCL97RB is a single wire light. The item is grounded through the mounting hardware and the base. 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.

  • 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.

  • 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 trailer...

  • 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...

  • 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.

  • 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...

  • 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...
