Optronics Trailer Lights - MCL67ARB

Highlights

  • Bright Front and Rear Marking: Amber faces forward and red faces rear so traffic sees you from both directions.
  • Reliable In Any Weather: Sonically sealed, waterproof housing keeps water out for lasting performance.
  • Slim Fit Anywhere: Thinline 4-1/16" x 1-1/4" body mounts cleanly on tight fender spaces.
  • Fewer Replacements Needed: 10 LEDs last 50× longer and draw only 0.048 amps at 12.8V.
  • Simple Power Hookup: One-wire plug and self-grounding bracket make installs fast and clean.
  • Clear Coverage: P2 rating gives a 90° beam pattern for proper clearance light visibility.

Features to know about

Better Fender Visibility: Dual-Face Amber and Red LEDs

Keeping both the front and rear of your trailer visible is simple with this thinline LED fender light. The amber lens faces forward and the red lens faces rearward, clearly marking both directions with a single fixture. It’s built around 10 bright white LEDs behind amber and red lenses that shine clean and even light. At 12.8V it draws only 0.048 amps, so it’s efficient without sacrificing brightness.

Confident in Wet Conditions: Sonically Sealed and Submersible

Water damage is no worry here. The lens and housing are sonically sealed into one waterproof unit, keeping moisture out even when fully submerged. It’s ideal for trailers that see wet roads or get dipped at the boat ramp since the circuitry and diodes stay dry and protected every time.

Smart Fit on Tight Fender Spaces: Low-Profile Thinline Design

When space is limited, this light fits right where you need it. The Thinline Series low-profile build measures 3-15/16" long x 1-1/4" tall x 7/8" thick, so it mounts close to the fender without sticking out. The included surface-mount bracket spaces its holes 3" apart on center for an easy fit and clean look.

Simple, Reliable Hookup: One-Prong Plug and Self-Grounding Mount

No complex wiring needed. This light uses a single wire for power and grounds through its metal bracket when attached to the trailer frame. Just connect the wire to your running light circuit, secure it with two screws through the 3/16" mounting holes, and you’re done—steady illumination with minimal effort.

Built to Last: Durable LEDs with Lifetime Warranty

The polycarbonate housing and lens resist impacts and wear, while the solid-state LEDs last about 50 times longer than incandescent bulbs. There are no filaments to break or bulbs to replace, meaning you can count on consistent light for years—and the LEDs are backed by a lifetime warranty for extra peace of mind.

3-15/16" x 1-1/4". Waterproof LED marker light can be installed on your trailer fender. Amber light faces front, and red light faces rear. Surface mount to trailer with bracket. Hardwired with 1-prong plug. P2 rated.

by:

Perfect light for mounting on your trailer fenders. It adds additional visibility for drivers approaching from the side and a great reference point when backing up the trailer.



by:

Lights I ordered came in fast. Well packaged. Once I figure out what size of screw I need to mount it, I will show pictures. This light is going to replace trailer fender lights that no longer work. Will use etrailer again as I will be upgrading all lights soon. Could not beat the price, as I'm using my money to help out the local high school band.



by:

My employer bought me a trailer with these exact lights installed. One worked, one was broke and missing. I was able to find these online, ordering and payment was easy, and shipping was fast. Installation was easy, and the LED lights are bright and look sharp!



by:

I purchased several lights and one round yellow clearance light has failed. I have not seen a vendor that made me pay to ship their failed product back. Unbelievable. The lights can be purchased from [online store] with no hassle returns



by:

I ordered 2 of these LED fender lights and they work great and they show up better than the old lights that were on fenders. They were easy to install and the everyone at etrailer took really good care of me. I have ordered from them before and will continue to order my trailer needs from them in the future.



by:

Very bright lights love them.



by:

Thought I was out of luck for this LED replacement on my horse trailer. Nothing in local stores. Did a search by part number on the old unit and etrailer popped up. Exact replacement right there and hit order. Took only two days or so and it arrived. Exact, same light and a new backing mount was also included. Great price, fast shipping and just what I needed! Thanks



by:

Perfect replacement



by:

Initially I didn't think I'd like these mid ship lights. The old ones were tapered down on the leading and trailing side of the lens so you could see them forward and back very well. As soon as i turned them on that concern was gone. There are 2 (or 4-can't recall right now) led's facing forward and back plus the row of led's facing staight out so they are very bright at all angles of viewing. I've bought enough overpriced junk led's in the past to know a quality light when i see one. All of the led's purchased from etrailer are top quality, completely sealed units. My only complaint was the packaging (and I'm not the only customer that complained). I hope etrailer has addressed that issue as i plan on purchasing all of my future trailer parts from them. This purchase was part of a complete restoration of a 1999 21'x8' Cherokee enclosed trailer.

Thank you so much etrailer.com for making this purchase easy! I will always recommend and utilize etrailer for all my trailer parts and accessories

The LED light itself is great. Wiring/Mounting this unit was nothing short of a royal PAIN. I would not buy these again as a result.

Ugh, it can be so annoying for mounting lights. What made it such a pain? I would love to look into some easier recommendations for you.

Placed them on my motorcycle luggage rack, as running lights of a sort. Work well, appear well made and easy to install.

Still working well, got a compliment from a motorist at at stop light saying it looked well done. Thanks



by:

The LED light was exactly the model I needed. I have the same light but a few of the LED's had stopped working. The nice thing about this light is that it's a plug and play part. Just unplug the old light and plug in the new one.

The LED light is still working perfectly although I will say that I do not use the trailer its on all that much



by:

Excellent replacement for the one that got broke.Light matched perfectly.



by:

Top quality- perfect replacement for previous lights. They were simple to install and work as designed. These lights are much more visible than previous, yet similar, lights. The best part of this purchase is the top-notch customer service at etrailer.com!

The products are just what I needed. I was particularly impressed with the order processing and the tracking with its use of maps to indicate the location of the package with the tracking information. I have never seen tracking enhanced to this level before. This is a company I definitely buy from again!

The product is working just fine and I will order additional items from this company when I need them.



by:

Product worked great. I have a 2013 Aluma trailer. The fender lights both broke off. When i called for replacement lights from Aluma, i got the run around and was finally told that 2 lights were $80 shipping included. I just about fell over. So, i took a risk and bought 2 of these. Great thing too because they were an exact match for way less AND the base was improved over that of Aluma. Easy install and everything.

Cassandra listened to my concerns and recommended what product I needed. She is very knowledgeable and it appears the lights I purchased are going to be excellent!

Really good lights, would be nice if a curved base option was available for curved wheel fenders. Needed to add shims to keep light base from bending

by:

Illuminates well when working. Failed in less than one year. E-trailer offered to warranty replace them but I had to pay for shipping back to them which was more than the cost of the lights. So I just ordered new ones.



by:

These lights are definitely the best I could find for my applications, they are water prove, large, bright, and well designed. I replaced my boat trailer and dump trailer lights with those. If they damaged I don't need to unbolt them, just pull the light of the base and push a new one in. Excellent product and great customer service.

  • Recommendations For Adding LED Marker Lights To A 20 Foot Cargo Mate Trailer
    You are correct. Red lights should always be as close to the rear of the trailer as possible. With that also said, if you wanted to use something like the Optronics Thinline LED Trailer Fender Light w/ Bracket # MCL67ARB on the fender, you will want the red light pointed towards the rear of the trailer and the amber light pointed towards the front of the trailer. If you do not already have the lights picked out, the Optronics Thinline LED Clearance and Side Marker Light # AL91RB (Red)...

    I have a complete replacement option for you, but just the lens portion of your light is not available by itself. Based on the model number on the rear of your light you will need the Optronics Thinline LED Trailer Fender Light - Submersible # OPT36FR which will be an exact replacement. With this you can reuse your current base, and just keep the new base on hand in case you need it in the future. I included a video of the # OPT36FR for you to take a look at.

  • How To Install the Optronics Thinline LED Trailer Fender Light
    The Optronics Thinline LED Trailer Fender Light part # MCL67ARB comes with a mounting bracket so as long as the surface you will be installing it on is metal then yes, it will work for you. All you would need to do to install the light is use two self tapping screws like part # 1131832 to mount the base and then once this is done you can attach the light to the base. To complete the process you will then need to attach the black wire to the running light circuit on your trailer which is...

  • How to Connect a Clearance Light with a Single Wire to a Trailer with Two Wires
    You can definitely wire a clearance light with a single wire to a trailer that has two wires. The first thing to know is that the two wires from the trailer are not positive and negative. Rather, they are the running light wire and the grounding wire. The running light wire (usually brown or black, but sometimes another color) is the wire that you connect to the wire coming from the light. To do this, use a butt connector like part # DW05744-5. The ground wire (usually white) from your...

  • How Does the Bracket # A67CB and Clearance Light # MCL67ARB Wire to Trailer
    The reason the # A67CB bracket uses a single wire is because the light will ground through the mounting hardware. If you needed to run a second ground wire to the assembly you would only need to run the stripped ground wire around the mounting screw that attaches to the side of the base with the ground strap. See picture I attached to see which side has the ground strap. The # MCL67ARB uses a similar setup and also grounds through the mounting hardware. The single wire coming from the...
