Optronics Trailer Lights - MCL32RB

Highlights

  • Bright, Low-Power Lighting: 3 red LEDs draw only 0.06 amps at 12.8V for clear visibility.
  • Built-In Reflex Reflector: No need for a separate reflector, keeping installs simple and clean.
  • Long-Lasting Design: LEDs last 50× longer than bulbs, so you won’t be changing lights often.
  • Durable Construction: White ABS housing and acrylic lens stand up to road vibration.
  • Road Legal: DOT compliant and P2 rated for safe clearance or side-marker use.
  • Easy Surface Mount: 4"x2" light with 3" mount spacing fits standard setups using 2-wire pigtail.

Features to know about

Brighter, Longer-Lasting Illumination: Efficient 3-Diode LED Design

No more swapping out fragile bulbs. This light uses three red LEDs that shine brighter and last up to 50 times longer than traditional incandescent lights. At just 0.06 amps on a 12.8V system, it delivers powerful visibility while keeping energy use low. It’s an easy way to upgrade to modern lighting that stays bright and reliable for the long haul.

Built-In Safety and Compliance: Reflex Reflector and P2 Rating

This 4" x 2" rectangular light includes a built-in reflex reflector, so there’s no need for a separate reflector to meet DOT compliance. The P2 rating delivers a 90-degree beam pattern—45 degrees to each side of center—making it ideal as either a clearance or side marker light. It gives your trailer the visibility it needs to be seen straight on in low-light conditions.

Simple Installation: Surface Mount with 2-Wire Hookup

Installing this light is straightforward thanks to its surface-mount design and standard 2-wire pigtail—one power lead and one ground wire. The mounting holes are spaced 3 inches apart (center to center), matching many existing setups for quick replacement or upgrade. Hardware isn’t included, giving you flexibility to use what suits your trailer best.

Durable Build That Handles the Road: White ABS Base and Acrylic Lens

Made with a sturdy white ABS housing and a snap-on acrylic red lens, this light is built to take vibration and road wear in stride. The lens can even be replaced separately if needed, saving time down the road. It’s a dependable, no-nonsense design that keeps your trailer lighting looking sharp and working strong trip after trip.

They were great

fit perfect to replace existing missing lenses



by:

Lights are as advertised, easy install and highly visible at night!



by:

On my RV I replaced the bulb amber side marker lights with the etrailer LED lights and wanted to do the same with the red side marker lights. Very pleased with the outcome.



by:

Well being a construction trailer one has been smashed at least 3 times but still functions with a little tape.
I will be replacing them soon with similar parts from etrailer

Great product and fast service

Great



by:

I replaced 3 incandescent lights in the center rear top with the led's. The new ones fit the same holes and worked great. Not sure how bright they are as I have not checked at night. If I replace the others I will order the 10 led's for the side marker lights instead of the 3.

Just like the Energizer Bunny. Still going.



by:

I bought this to replace a broken original marker light on our 1995 motorhome.

Pros - LED, sleeker look than original, easy to wire if you are familiar with wiring lights for vehicles/trailers, priced better than incandescent.

Cons - The screw holes are closer together than my original fixture but I drilled a new pilot hole for the second screw and it was fine, the light sticks out further than the original, and I don’t like squatting or kneeling in order to fix things, anymore (but that’s just a reflection on me and not the light).

There have been no problems whatsoever with the light. I don’t give it a second thought.

Nice size light to mount on 2" angle iron that I'm making a light bar to mount on the rear and top of my pickup bed. I'll be using the light bar while towing the pickup behind my motorhome this winter. I am using 2 of the these lights in the center of the light bar. I'll have 2 larger lights with brake and turn signals on each end of the light bar.

The lights mounted easily and were the right size plus they were bright!!!



by:

The clearance lights work perfectly. The sales lady went above and be beyond to make sure they were correct.
She even went back in the data and found a previous order I made. Very professional!



by:

Great prices ! ,fantastic service,fast shipping = 100% satisfaction! :-) thanks



by:

All products I have ordered from etrailer recently have been good quality at a fair price. Service is good and orders shipped promptly. There are videos about each product as well as installation videos. Good reliable company



by:

Easy enough to install...getting the old one off was the tough part. Much brighter than the old incandescent lights.



by:

I did receive the wrong light initially, but had the right one expedited to me quickly after I called. It was an easy replacement.



by:

Had lost one lens on a 2002 model year 5th wheel. Decided to replace all red lights. Install went well. Lights are brighter - haven't seen them yet after dark but I'm sure the camper will be more visible if we travel at night or foggy conditions. I was surprise how quickly they were promised to arrive and they did arrive on schedule.



by:

This is my second order of these lights. The first order was a test to see if I like the way they look to replace my old cracked and dirty incandescent lights. Once I put the new lights on my trailer, I knew I had to replace all of my lights because they look so great! They make my old 1999 Jayco look like new!



by:

Replaced all the clearance/marker lights on my 2007 RV. Nice upgrade to the LED and very easy installation.



by:

I am sure the product is of average quality, however when you purchase multiple items from etrailer (some of substantial weight) and they box everything together without any packing materials to keep fragile items safe, the comfort and likeness of purchasing items through this retailer drops. Brought this up with their customer service, and they said it was packed properly.



by:

Replaced burned out incandescent clearance light with LED. Been doing that with all my incandescent lights as they fail. Worked great and fantastic price. Wiring info on the etrailer web site also helpful. This was the closest match to the originals.



by:

Well, they are just lights – amber and red. But, I upgraded all my trailer lights to LED’s, and these continue to look and function great.



by:

All 14 clearance lights fixtures where just tossed in a box without padding and shipped… so all of them bashed around and against eachother none broke but now I have to polish all the scuff marks off each and every one of them. They definitely don’t show they care about your product you buy from them. I will more than likely not buy from this company again.



by:

I replaced all the incandescent running lights on my RV with these LED versions last year. The installation went as expected and they new lights are brighter and operated perfectly all season long. The information provided by etrailer online was exactly what was needed to make the proper selection and the service was exemplary as always. Thank you etrailer!

The Optronics LED lamps have worked perfectly for the past year. Ive had no problems with them and theyre much brighter than the incandescents I replaced. As always, ETrailer provided the perfect solution to my upgrade requirements!

  • Replacement For Bargman 34-59-012 Clearance Lights
    Hey Bill! Yes, the LED Trailer Clearance or Side Marker Light w/ Reflex Reflector # MCL32RB is a direct replacement for your discontinued Bargman 59 series lights. For amber you can use # MCL32AB. Any big trips coming up this spring once you get your lights replaced?

  • Installing LED Clearance Lights With 2 Wires
    Two-wire LED clearance lights such as the Red # MCL32RB or the Amber # MCL44AB have one wire for the power lead and one ground wire. The wire that was attached to your old clearance lights will be spliced to the power wire of your new lights. The black is power and white is ground for these lights. If you take a look at the video I have linked you can see how these lights are installed. I have also attached a couple of links to help articles on trailer wiring which you should find useful.

    Hello Kurt, I can definitely help you out with the right clearance and side markers for your 6 x 12 dump trailer. I attached an image to reference for the lights/reflectors, these are the DOT requirements: - Rear reflector (#4 on diagram) 2 of the # PE72ER - Rear-side marker light/reflector (#6a/6b) 2 of the # MCL32RB - Front Side marker light/reflector (#7a/7b) 2 of the # MCL32AB You will want to use at least 16 gauge wire and some butt connectors like # DW05744-10.

  • Looking For Clearance Light To Replace Bargman 59 SAE A P2 83
    Hello Robert. I was able to cross reference the part number you provided to the Bargman #59 Series clearance lights. These lights have unfortunately been discontinued, so a direct replacement is not available. We do have a light that is virtually identical, the Optronics LED Trailer Clearance or Side Marker Light # MCL32RB for red and # MCL32AB for amber. This light is 4" long x 2" tall x 1" deep so identical in size to your old Bargman lights.

  • Need Replacement Tail Light Lens For SAE P2 A 99 Light On Lazy Daze RV
    Hello Don, thanks for reaching out. Normally the SAE number isn't a reliable way to find the correct replacement as it is not a part number. I have seen this number come up before and we do have it in our records. It comes back as a 4" x 2" red clearance light from Bargman. Sadly, this light and lens are no longer available so our best option would be to replace the light entirely. For that, I recommend the following: - LED Trailer Clearance or Side Marker Light w/ Reflex Reflector...

  • Replacement LED Red Clearance Light For A Bargman 58-Series Clearance Light
    Hey Luis, For an LED version of the Bargman 58 series clearance light you would want the LED Trailer Clearance or Side Marker Light w/ Reflex Reflector # MCL32RB. This is a surface mount design so you'll need to pick up some self-tapping screws and I'd also recommend using some butyl tape # AL28FJ on the backside of the mounting base to help prevent any water from leaking into the wall of the trailer.

The closest light we have to that old Glo-Brite model is the Optronics Clearance Lights # MCL32RB if you want LED or # MC32RB if you want incandescent.

  • Looking For Replacement Light Lens For 2011 Puma Travel Trailer
    Hello Barbara, thanks for reaching out. I can point you in the right direction, but the SAE number is not actually a part number for the light, so there is no way to use this to know exactly what light you have. The SAE number just means the light is compliant with DOT/SAE regulations, and this number can be found on most any trailer light. The best way to determine what lens you need will be to either find the part number for your light, or to compare the size and shape of the light...

    Thanks for providing the picture. It looks like your current marker light is around 3 3/4" long and 1 1/2"- 2" wide and has mounting holes 3" apart. While we don't have anything in those exact dimensions, we do have several that are slightly larger so when you replace yours you will be able to completely cover the space the old lights used to be.

    Thanks for the photos and it looks like you have found exactly what you need with the LED Trailer Clearance or Side Marker Light # MCL32RB. This light measures 2 inches tall (and 4 inches long), which is what it looks like yours measures, and it has mounting holes that are 3 inches apart on center, which I'm guessing is what you got when you measured that. This light will work well as a replacement for you. I've added a link to a video review as well.

    The Optronics Red LED Trailer Clearance or Side Marker Light # MCL32RB will come from their factory in Taiwan. If you are looking for clearance lights that are made in the USA I recommend the Peterson Double Bullseye Clearance and Side Marker Trailer Light in Red # 425800 or Amber # 425600. These have the same 4" long by 2" wide footprint but use bulbs rather than LED's. The bulbs can be swapped for LED's # DI88VR if you prefer the lower power draw and longer life of LED lights.
