This waterproof identification light bar with 3 lights is 15-15/16" long and designed for trailers wider than 80". Durable polycarbonate housing and lens. Surface mounts to trailer - hardware not included. 2-Wire design. DOT approved.


The light bar worked out great! Nice addition to the back of the trailer.


I changed out all my trailer lights to LED and they work great!


All of the items I’ve ordered over the past five years have been as described, always fit as shown and are totally satisfactory in their function and appearance. I design for looks and the variety of lights and videos of how they’ll appear have helped me immensely in the redesign of my classic GT race car’s taillights (and its trailer’s lights too which have arrived and are waiting to be installed).



A year and thousands of miles later, the lights still work flawlessly.


the lights are bright! did have to make new holes into the light plate to accommodate the different spacing of the bolt locations.


Easy to install. The wires was long enough to cut for proper length. They are bright and look really nice.


I want to thank you for all your help with my trailer you were more helpful than you realize. So this is my trailer for a 22' Flats Cat shallow draft Catamaran. I totally dismantled my trailer and buffed by hand with a wire buffer and sand blasted in some spots and applied multiple coats of some very expensive galvanize paint (Z.R.C.). I installed all new C. E. Smith Carpet (about 80'), seven new LED waterproof lights, new springs, new equalizers, new tongue jack, new wench, new safety chain, new chain brackets, all new SS hardware and a 35' long wiring harness.
I was able to send only one review with a picture of the safety chain and brackets. I'm having a little trouble with the rest..oh some of these items were bought locally or from your competitors, until I found etrailer. Your prices were cheaper for the exact same things. Your helpful how to videos were helpful. And Rose, your personal helpful knowledge made my buying experience very pleasant, I actually enjoyed talking to you! Thanks to etrailer and specifically to Rose G.


Still just as bright as the day I bought it,and installed on my boat trailer!!!!
Still going strong after a year!!!!
Been under the water many times at boat ramps...... and loving the waterproof light!!!!! Would definitely buy from again!!!!! Thanks do much!!!!


Good product. I just installed it so I can not vouch for longevity. The factory halogen single wire setup on my boat trailer was failing within a year, so I did a complete trailer light overhaul. This light bar is nice and bright, and with it being sealed LEDs SHOULD last quite a while. The plastic does seem a little flimsy, but I bet I won’t have any issues with it unless I somehow smack it into something. Can’t really see the whole light in my photo, but you can see how bright the one light that isn’t hidden by the motor is.

In short, I would recommend this light.


Exact replacement. Very easy installation. Nice and bright.


Just received and installed this light today. Replaced 7 year old lights on my utility trailer hoping to not have to mess with light bulbs anymore. The light works as it should, it's nice and bright, arrived in a reasonable time frame, was packaged well, and hopefully will last. I have ordered many items from etrailer and have never had a problem.


Worked perfectly without the need to purchase the entire light


Amy is awesome, very professional and h elpful


Good fit and priced right. Configured exactly like the old light bar.


Great product and extremely bright


Nice, I ordered with aluminum ramps and they were under them during shipping but did not break them. Easy to install


These replaced the OEM lights on a Shorlander form 2012. Easy to install and everything looks great.


Fit perfectly and very bright


Works great. Two new holes for mounting. Added two photos, old lights and new.


good quality works as it should


Excellent product. Very bright.


This Optronics LED light bar is BRIGHT! I decided to upgrade all my 20+ year old incandescent boat trailer lights primarily to eliminate the hassle of replacing bulbs and light modules every year or two. I was extremely pleased to find that in addition to the promise of longer life, they are extremely bright and I feel much safer now when pulling my boat trailer day or night. This one is plastic but it seemed sturdy enough when mounting on back of my trailer.



After one year going in and out of the water at boat ramps and the trailer being exposed to the elements when not being towed, these lights are still bright and like brand new.


Very slow delivery time. Wouldn't order again


great product fast service


Great service on my order!


They mounted very nice and look great on the trailer

  • Is the Sealed, 3-Light Truck, Trailer Identification LED Light Bar # MCL93RB Street Legal
    Yes, the Sealed, 3-Light Truck, Trailer Identification LED Light Bar # MCL93RB is rated for use as a marker/clearance light at the back of your box truck.

  • Is Sealed, 3-Light Truck, Trailer Identification LED Light Bar Submersible
    The lights themselves on light bar # MCL93RB are sealed so water cannot get into them. This does make them submersible as well. All sealed lights are submersible but not all submersible lights are sealed. I have linked a video review of this light bar for you.

  • Diameter of Mounting Holes in Optronics MCL93RB LED Identification Light Bar
    The mounting holes for the # MCL93RB ID Light Bar are 3/16 inches in diameter, I'd recommend using 3/16 inch stainless hardware and a 7/16 hole in the trailer frame. Stainless bolts, nuts and washers should be readily available at your local hardware store. If you click the provided link, you can see a product demonstration video for the # MCL93RB Light Bar.

  • Is there Specific Mounting Hardware for 3-Light Truck/Trailer Identification LED Light Bar MCL93RB
    There isn't specific hardware designed for Sealed, 3-Light Truck, Trailer Identification LED Light Bar, Black Base, 50" Lead, 9 Diode -Red Item # MCL93RB. You would use hardware appropriate for the mounting surface the light will be attached to. This allows you to choose your own hardware which will likely cost you less money since you won't have to pay to have hardware shipped to you.

    The MCL-83 measures 17 inches long overall and 1-1/2 inches deep. It draws 0.141 amps at 12.8 volts. Light MCL-93, # MCL93RB, is 16-1/2 inches long overall and 1-5/8 inches deep. It draws 0.051 amps at 12.8 volts. Both are LED lights just with different measurements and power draw ratings.

  • Checking/Fixing Ground Connection on Trailer LED Light Bar
    From what you describe, it sounds exactly like a ground problem. You'll want to make sure the ring terminal on the ground wire is making contact with bare metal on the trailer frame. If there's paint or corrosion preventing the ring terminal from making good metal-metal contact, you'll only pick up the ground connections through the threads of the ground screw, which sometimes isn't sufficient. To refresh a ground connection, I like to remove the ground screw, sand down the area around...

  • 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...

    The LED Identification Light Bar for Trailers over 80" Wide - Submersible - 9 Diodes - Red Lens # MCL93RB has the wiring and housing for the individual sealed lights # AL91RB to fit. The only way to help them stay in place a little better is to add silicone around the edges to just add an additional seal that will hold up to vibration and water. An alternative option is to use the LED Identification Light for Trailers Over 80" Wide - 3 Diode - Sealed - Rectangular - Red # MCL98RB which...

  • Plug-n-Play Tail Light or Light Bar for Towing
    We have the Heavy Duty Magnetic Tow Lights # TL21RK from Optronics that already uses a 4-Way wiring harness. All you have to do is string the excess wiring over the vehicle that you are pulling and plug the 4-Way from the Magnetic Tow Lights it into the 4-Way at the rear of your tow vehicle. If you are looking for a Light Bar, I recommend going with the Sealed, 3-Light Truck, Trailer Identification LED Light Bar # MCL93RB. You will have to splice this into your current wiring, and this...

  • Amber Version of the Clearance Light part # MCL98RB Availability
    To get an amber, LED version of the part # MCL93RB you would need to order replacement lens part # A91AB and then replace the red lenses with the amber lens. On the front of a trailer you need to have the amber lights displayed and on the back red.

  • Recommended LED Light Bar For The Back of An Enclosed Trailer
    The LED light bar strip I recommend is # MCL93RB. Each strip has 3 LED lights on the base. They are sealed, waterproof and corrosion resistant. Contains both lead wire and ground wire for mounting to all surfaces. The LED light bar strip # MCL93RB is a two wire system meaning you will have one wire with a ring terminal for your ground, and a 50-inch power lead wire. You will connect the white wire to your ground and the brown power wire lead to your power supply. I included an FAQ and...

  • Submersible Light Bar Recommendation for Trailer Lighting
    I have a solution for you, but the Peterson Lightbar part # 136-3R that you referenced is not submersible. Instead check out the # MCL93RB which is a very similar light bar that is submersible.

  • LED Identification Light Bar and Trailer Taillight Kit for 2012 Yamaha Trailer
    Yes, both of the LED trailer taillight kits you mentioned would work great on our 2012 Yamaha trailer. The LED Identification Light Bar # MCL93RB and the Optronics LED Combination Trailer Tail Lights # TLL160RK. These are both LED like you are wanting which means more reliable and less amperage draw, can easily fit in place of what you have now, and are submersible too.

  • Recommended U-Bolts, Rollers and Boat Trailer Lighting/Wiring for a 1984 Shoreline Trailer
    Thanks for sending us the pictures! Since you are installing a Bolster-and-swivel-bracket assembly part # CE10001G-4 and need a 4-1/8 inch width by 3-1/2 or 4-inch length U-bolt, we currently don't offer a close match. I would recommend going to a local hardware store to locate a U-bolt with the dimensions you need. I would go with a stainless steel u-bolt because it is corrosion resistant and ideal for marine applications. For the lighting and wiring on your 1984 Shoreline boat trailer,...

  • LED Light Kit for Trailer Over 80 Inches Wide
    The "80" you are referring to is the width of the trailer, and it makes it easier to determine the light kit you need. Since you need tail lights as well as running lights, I recommend the Trailer Light Kit for Trailers Over 80" Wide # TL16RK. This will give you the Stop, turn, tail, side marker, rear clearance, side reflector, rear reflector, and license plate light that you need for your trailer. For the light strip with three lights you were referring to you will need the LED Identification...

  • Best Light For Bike
    You could make the LED Bar # MCL93RB battery powered but we don't carry any batteries that would work with it. Also, the red light won't really show a whole lot of light. What I recommend getting is the Furrion LIT # FBS012NVPPS. This kit comes with a handlebar mount that will mount this speaker/light to his bars. This will be a lot brighter and he can also listen to music as well! When you're not using it as a light on his bike you can also use it as a speaker on other adventures. I recommend...

  • Recommendation For LED Boat Trailer Light Kit For Submersible Applications
    Sounds like you need something like the Submersible Over 80" Aero Pro LED Trailer Light Kit w 25' Wiring Harness, Item # TLL36RK. The lights in this kit are sealed and have a waterproof construction. The LEDs are very efficient and last 50 times longer than incandescent bulbs. This kit is for trailers that are over 80 inches so if your trailer is under 80 inches then you can use a similar kit, Item # TLL9RK.

For a complete light setup you need the following: - Optronics Trailer Light Kit for Trailers over 80" Wide # TL16RK - LED Identification Light Bar for Trailers over 80" Wide # MCL93RB I'm also attaching a link to our helpful article on trailer lights for you to check out.

    I don't offer a kit that would include everything you mention, but I can suggest a kit to use as a starting point plus the additional lamps to complete your setup.

To get the trailer set up the way you're wanting, you'd need an additional 4 of the # MCL-91AK lamps and a # MCL93RB 3-lamp identification bar. These lamps are all...
