Features to know about

Brighter and More Efficient Lighting: 9-LED Identification Bar

Round amber LED trailer clearance and side marker light with clear domed lens and surface-mount design, shown against a plain background.

Old incandescent bars draw more power and fade fast, but this 14-1/4" long LED identification light bar keeps things bright and efficient. It uses three replaceable Optronics MCL series lights, each with three LEDs for a total of nine diodes. At 12.8V, the entire bar only draws 0.153 amps. That means strong, even light output with very little power use—and no fragile filaments or bulbs to replace.

Protection Against Water Damage: Fully Submersible and Sonically Sealed

Water and road grime are tough on trailer lights, but this one is built for it. Each light is sonically sealed to make the housing and lens one waterproof piece. The stainless steel base resists corrosion while the polycarbonate lens protects against impact. Whether it’s rain, washdown, or full submersion, the LEDs stay sealed and safe so you don’t have to worry about moisture ruining your lights.

Simple Hookup and Mounting: Single-Wire Design with Integrated Ground

Wiring doesn’t get easier than this. The light uses a single wire that connects to your running light circuit, while the stainless base grounds through the mounting hardware—no separate ground wire needed. The 8-1/2" hole spacing on center makes it easy to line up existing mounts for a clean surface install. Hardware is included so you can bolt it right on without extra parts.

Built for Compliance and Visibility: DOT P2/P3 Rated

Tekonsha Prodigy P2 trailer brake controller installed under vehicle dashboard with illuminated digital display and control buttons for trailer braking adjustment.

Staying legal and visible is important when your trailer is over 80" wide. This identification bar meets DOT standards and carries a P2/P3 rating for a clear rear beam pattern that’s easy to see from straight on. It gives your trailer the required rear ID lighting in one durable, sealed assembly that’s ready for road or ramp duty.

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.



by:

For my Hobbie 16 boat trailer.



by:

Love them! Nice and bright!



by:

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.



by:

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.

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.

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!

Still going strong after a year.

Excellent product. Makes the trailer sh ine.



by:

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



by:

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

:-)



by:

Item looks the same as what I have on my trailer already. But I thought I would try the LED version since it seems there is no easy way to change the bulbs in the "older" model. The wiring is a little different though as my current trailer has the white grounded wire also. I'll have to double check that this is self-grounded as the packaging mentions.



by:

Item was shipped and received in a timely fashion. Quality and good service make for a happy customer.
Thank you eTrailer!

@Neil you're welcome. Glad you're happy with it!

Great replacement for the original incandescent light bar on my 1997 Shorelander boat trailer. Same hole pattern, so no drilling.



by:

Customer service was good, kept me up to date on my order. And fast shipping.



by:

The Light bar is good quality. I would have liked to have two wires on light bar instead of just the one wire. My trailer has two wires a negative and positive. The light bar frame is considered the ground so attaching the light bar with screws to trailer frame grounds the light bar. What do I do with my ground wire now?



by:

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.



by:

Updated my boat trailer with these amazing bright lights. Easy installation using the heat shrink connectors. Everything came as exactly ordered.

  • What is Blue Piece For Optronics Identification Light Bar
    Hello Frank, Thanks for the purchase and the blue piece of the Identification Light Bar for Trailers over 80" Wide - Submersible - 9 LEDs - Silver Base - Red # MCL97RB is a quick splice.

  • 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...

  • 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 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...

  • What Lighting Function Runs to Optronics Light Bar # MCL97RB
    I found your order notes and it looks like you bought the Optronics light bar part # MCL97RB which is actually a single function light. It only would have the running light circuit ran to it.

  • 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...

  • 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.
