Optronics MCL70 Series Ultrathin LED 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.

UltraThin ID Light Bar for Trailers over 80" Wide - Submersible - 3 Diodes - Red Lens - MCL70RB

Average Customer Rating:  4.8 out of 5 stars   (99 Customer Reviews)

15" Long x 1-3/8" tall x 5/8" deep. Waterproof identification light bar is designed for trailers wider than 80". Durable polycarbonate lens and housing. Surface mount to trailer. 2-Wire design. P2 rated.


Appears to be an exact duplicate of the OEM light on my 2017 Ranger Trail trailer. Aligned perfectly. (Check your mounting hole measurement b4 ordering). Time will tell as to it's waterproofing, but for the cost... if I get 37 months out of it, it will have outlasted Ranger's OEM light that cost $xx+ to replace

After 12 months, I havent had any issues and it is working as expected.

Quick delivery
The right part was shipped

This is why I return to etrailer
Thank you.


Great product, very bright and high end material usage.


Happy with purchase. Appropriately bright. I ran the white wire inside the trailer chassis and grounded it; I could have just as easily run it to one of the self-drilling light bar mounting screws. Like another reviewer, I flexible-caulked around the light bar.


Awesome looking light. These units are slightly shorter than the stop/turn/tail with reflector. It would be nice if they matched or if there was shorter stop/turn/tail with reflector to match it, but only 1/4 inch difference not too bad. Also, the LED circuit board is open on the back side of the light. I will be filling it with silicone or dielectric grease before mounting and then caulking around the mount to make it water tight.


I used this on the rear of my car trailer. Worked great and brighter than the stock ones. However, I smashed it backing into a tree. This one worked so well I’ll probably just buy it again.


I have bought several items over the past few years from etrailer and get great customer service and good products always. The prices are good and the time it takes to get the product is pretty fast.

the products that i purchased work just as i expected them to and your company is great to work with

Great parts fast and a toy for our buddy !


Arrived on time well packaged with no damage and was what was advertized. Mounted easily on my trailer, the LED's are brighter than the 3 marker lamps it replaced. A Good product at a reasonable price.


Needed this for a flatbed trailer I bought that needed to be brought up to standards for it's size. Bought many things from Good prices, good quality, good information.


Your suspension parts and the wiring components exceeded my expectations. Just as pictured and very good quality. I'll be back again and again You're easy to do business with and the shipping is very prompt. Good job, folks!


like the slim design. Seems like the marker lights on flatbed trailer are always getting broken and the slimmer design helps protect them some.


Easy to install, quite bright. Was the best solution for my tilt bed trailer.


Cheapest LED light out there. Great quality and even better service!


Great product quality.....Right on time. This is my second order from> They will be getting my business in the future.


Great quality product for extra visibility on my enclosed trailer

  • Is the Thinline LED Trailer Tail Light Available As a Clearance Light
    The Thinline LED Trailer Tail Light part # STL64RB has three functions; stop, turn, and tail. If you are looking for a similar style of light with the clearance function capability then you can use the UltraThin ID Light Bar part # MCL70RB. If this is not what you are looking for please just let me know and I would be glad to see if we have other options for you.

  • Comparing Optronics Aero Pro and Glolight Trailer Tail Lights
    There would be a noticeable difference if you had both the Aero Pro light # STL37RB and the Glolight, # STL117RB right next to each other. You would notice that the Glolight seams to actually sort of glow rather than just light up. This is due to the top and bottom bars that light up solid. Both lights are going to be plenty bright. Light # STL37RB has 23 diodes which will be very bright as you can see in the picture submitted by reviewer Becky P. She is using tail lights # STL37RB and...

    The UltraThin ID Light Bar for Trailers over 80" Wide - Submersible - 3 Diodes - Red Lens # MCL70RB is 15" Long x 1-3/8" tall x 5/8" deep. This is probably the most similar option but there isn't an amber options for this one. The 3-Light Truck and Trailer Identification Light Bar with White Base - Amber # MC99AB is 16-3/4" long x 1-3/8" tall x 1-7/16" deep will match the Identification Light Bar for Trucks and Trailers - Incandescent - White Steel Base - Red Lens # MC99RB.

  • Correct Converter To Add Third Brake Light To a Trailer
    In order to separate the stop light circuit on your trailer for use with a third brake light you will need to use the Pacer Performance 3rd Brake Light Logic Module part # PP20-702, not the Tow Ready Tail Light Isolating Diode System with 4-Pole Connector part # TR118821. Then for a third brake light, I like the UltraThin ID Light Bar for Trailers part # MCL70RB but have attached other options for you as well.

  • Replacing Lights and Trailer Connector on Boat Trailer Over 80 Inches Wide
    Although there isn't a specific kit available that addresses all your needs, you can use a light kit designed for an over 80 inch trailer like # TLL36RK and modify it so it will work. You'd need some extra wire, # 16-3B-1, an ID light bar for the middle of the rear beam that would tie into the running light circuit, part # MCL70RB, a molded trailer connector, part # H20046 and a junction box, part # 38656. The install would be pretty straightforward. The molded connector would run to the...
