Features to know about

Brighter and More Efficient Lighting: Long-Lasting LED Design

Old incandescent bulbs just can’t keep up with LED performance. This oval clearance or side marker light uses a single white LED behind a red lens that lasts up to 50 times longer than a regular bulb. At 12V it draws only 0.073 amps, giving you bright light with minimal power use. That means less strain on your electrical system and no bulbs to replace down the road.

Easy Mounting in Tight Spots: Slim, Surface-Mount Fit

When space is limited, this low-profile light fits where bulkier housings won't. Measuring 3-3/4" long x 1-13/16" tall x just 3/8" deep, it sits nearly flush once installed. The surface-mount design uses two holes spaced 2-11/16" apart (center to center), so installation is quick and clean without needing to cut large holes—just run the simple 2-wire pigtail and secure it with your choice of hardware.

Built for Visibility and Compliance: P2-Rated Beam Pattern

Visibility matters for safety, and this P2-rated light produces a 90-degree beam pattern—45 degrees to either side of center. That’s ideal when you need a dedicated clearance or side marker light that meets lighting standards and keeps you visible from the right angles on the road.

All-in-One Functionality: Built-In Reflex Reflector

No need for a separate reflector—this light already has one built in. The integrated reflex reflector enhances visibility even when the light isn’t on, catching headlights and helping others see your trailer at night or in low light. It’s one small part that does double duty for safety and simplicity.

Durable and Straightforward: Snap-On Polycarbonate Lens

Made with a rugged polycarbonate housing and snap-on lens, this light is built to withstand wear and tear from the road. The sealed design keeps the LED protected while allowing easy lens replacement if it ever gets damaged. It’s dependable, efficient, and built to last through years of use.

Another exact match for our camper after a tire blow out took out some of our lights.



by:

These led marker lights were the perfect replacement for my 17 year lights on my motor home. E trailer on hand is the slowest in processing the order and getting it out to the customer.

Installation was easy. The fit and design matched the original. After a year, the light still works perfectly. My only regret is that I waited so long to replace the original broken light.

My trailer marking light is still working well. Thank you etrailer for your help.



by:

Exact match for the light I needed. Delivery was super fast!



by:

I was very happy to find this reflector because the ones made by glo brite, which are used on the Winnebago Navion and Views,are no longer made. This one looks like it will be a very good match!

Excellent ease of ordering and excellent customer service from etrailer.



by:

Great communication. Right parts. Already installed. Thanks Joanne



by:

Easy to install and they work. That’s all you can really ask for. Direct replacements for factory lights.



by:

Good replacement for a part that is no longer available. Simple install on 2007 Navion. Quick delivery to keep me legal on the road



by:

I bought 3 of these marker lights to replace the original clearance lights on my RV since they were more or less the same size. With only one diode (many of my other marker lights have between 4 - 15) I was initially concerned about their brightness, but once installed I was happy with the amount of light they emit.



by:

Just what we needed. Easy install. Works fine.



by:

Good service. Received what I ordered and product was what it showed.
Will use again.
Thank folks



by:

This Light is a direact replacement to the original equipment. Took off the old and they fit perfectly. Great value, great product.



by:

Almost identical match to the Glo Brite clearance light that is no longer available.. Black wire is positive white is ground..



by:

I had one of these particular lights that didn’t work on our 2019 Rockwood travel trailer, and after checking the wiring, I discovered it was the light. The new light was ordered, and delivered quickly. I have installed it already and it works as it should.

  • How to Determine if Optronics Clearance Light MCL0030RBB is Right For Trailer
    Hey Jeff, While we don't have any way to confirm the exact lights on your trailer, I can tell you the SAE is just a type of safety code, and there isn't a 131 with an oval lens. That said, the LED Clearance or Side Marker Trailer Light # MCL0030RBB could still be right for you. To find out, you can just measure the light you have and match it up; the # MCL0030RBB is 3-3/4" long x 1-13/16" tall x 3/8" deep and its mounting holes are 2-11/16" apart on center. If your light has that - or...

  • Replacement For SAE AP2 17 DOT Trailer Marker Light in Red & Amber
    Hi Daniel; thanks for the question and I can absolutely get you the replacement red and amber trailer marker lights to replace the SAE AP2 17 DOT. What you need for both are the following: - Red: LED Clearance or Side Marker Trailer Light # MCL0030RBB - Amber: LED Clearance or Side Marker Trailer Light # MCL0030ABB

  • Replacement Clearance LED Lights For A 2018 Thor Chateau 28Z Class C Motorhome
    Hey Ed, Typically the light cover will have some small indentation for you to stick a pry tool in and pop off the cover. You can see if there's an actual bulb in there or more likely just led diodes. If it's a bulb you can look at the base for a bulb type and find a replacement. If it's just diodes then you'll be replacing the entire light. If you are needing to replace the light then you should be able to see the two mounting screws holding the base of the light to RV and can remove...

  • LED Clearance Lights for 2014 Itasca Navion
    Hey Vernon! Are you looking for a particular style? The pictures I could find of the 2014 Itasca Navion didn't give a clear view of the running lights so I'm not entirely sure what is on there right now. I don't have an exact match on the mounting holes but for 3-3/4" lights you could use one of the following: -LED Clearance or Side Marker Trailer Light w/ Reflector # MCL0030ABB -LED Trailer Clearance or Side Marker Light with Reflex Reflector # 328-K-58LB.

  • Availability Of Replacement Lens For Glo Brite 122R/122Y Marker Lights
    Hey Mike, thanks for reaching out. What you have there is the Glo Brite 122R/122Y lights. We do not carry this brand, so we do not have a lens for this. We do have a suitable replacement for the light itself though. Take a look at the following: - LED Clearance or Side Marker Trailer Light w/ Reflector - 1 Diode - Oval - Amber Lens # MCL0030ABB - LED Clearance or Side Marker Trailer Light w/ Reflector - 1 Diode - Oval - Red Lens # MCL0030RBB

  • Replacement Light Solution for Glo Brite 122R
    Hey Tom, we have lights that are similar to the Glo-Brite 122R light but not exact replacements. I recommend the Optronics Clearance or Side Marker Trailer Light - Incandescent - Oblong - Red Lens # MC68RB and Amber Lens # MC68AB which are 3-1/2" long x 1-1/8" wide x 1" thick. Would this work for you?

  • Replacement Clearance Lights For Glo Brite 122r/122y
    The Optronics LED Clearance or Side Marker Trailer Light is available in Red # MCL0030RBB and Amber # MCL0030ABB. These are the closest replacements to the Glo Brite 122r/122y lights you have. The lights only have one LED diode versus the 3 in your light. You are able to get a replacement lens in either Red # OPT67WR or Amber # A0028AB if your lens becomes damaged with the new lights.

  • Replacement Red and Amber Clearance Lights For a 2008 Winnebago Adventurer 35L
    It looks like you will need to replace the entire light assemblies on your 2008 Winnebago Adventurer 35L as the lens mounts for the Optronics MCL0028 # A0028AB uses a different mounting style than the lights on your Adventurer. You current lights are discontinued and no longer available. I recommend replacing your current assemblies with the Amber LED Clearance Light # MCL0030ABB and Red LED Clearance Light # MCL0030RBB. These LED assemblies won't require you to replace bulbs like your...

  • Replacement Clearance Lights For 2007 Winnebago Sightseer RV Motorhome With Glo-Brite 122R/122Y
    I do have a recommendation for you as we do not have a direct replacement cover for the Glo-Brite 122R/122Y cover. Instead we do have the LED Clearance or Side Marker Trailer Light in Red # MCL0030RBB or Amber # MCL0030ABB. This will allow you to replace your lights and then you will be able to use the Replacement Covers in Amber # A0028AB or Red # A0028RB if one of the lenses should become damaged on the new lights.

  • What Is The Difference Between Lights With 1 And 2 Diodes?
    Hello Dave. The 1 or 2 diodes simply refers to the number of light emitting diodes (LEDs) housed inside each light. More diodes does not necessarily mean a brighter light, it just has to do with the construction of the light. You can definitely get by with 1 diode. If you are replacing old lights you will just want to verify that the new lights are identical in size to the old ones. The LED Clearance or Side Marker Trailer Light w/ Reflector - 1 Diode - Oval - Red Lens # MCL0030RBB is 3-3/4"...

  • Correct Replacement Lens for LED Clearance or Side Marker Trailer Light MCL0030RBB
    We do offer a replacement lens for the LED Clearance or Side Marker Trailer Light part # MCL0030RBB, it's the Replacement Lens for Optronics part # A0028RB. That said, for only a few more bucks you can get a new assembly with bulb so I would just get a new light if I were you.

  • Parts Needed To Add Running Lights To a Hitch Mounted Folding Cargo Carrier
    I have a couple options you might consider. First is the easiest and would involve the Auxiliary Lights # C53201. The lights themselves adhere with double sided tape to your cargo carrier and the wiring can easily be run through your center post to keep everything tidy. These lights are going to function as running lights, turn signals and brake lights. If you prefer to only use marker lights you could cut off the 2 male terminals on the connector which activate the turn/brake lights. If...

  • How To Find Replacement Rear Clearance Lights for a 2008 Fleetwood Southwind
    In order to find the correct replacement rear clearance lights for a 2008 Fleetwood Southwind you'll need to take some measurements, note the shape and color then choose from our selection which I have attached for you below. I don't have a way to look this up for you. The lights appear to be oval so something like the LED Clearance or Side Marker Trailer Light part # MCL0030RBB may work.
