Features to know about
Simple Fix for Worn-Out Trailer Lights: Easy Surface Mount Design
When an old light cracks or burns out, this one makes replacement simple. The Optronics Mini Trailer Clearance or Side Marker Light measures 3-3/16" long by 1" tall and mounts flush with the surface using the included hardware. The single-wire design grounds through the mounting hardware, making wiring straightforward and clean.
Reliable Visibility Every Time: P2-Rated Red Incandescent Light
Good lighting matters for safety, and this light does the job well. It uses a replaceable 194 incandescent bulb behind a red snap-on lens to give steady illumination on a 12V DC system. As a P2-rated light, it provides a 45-degree beam angle on either side of center for a total of 90 degrees of coverage—perfect for use as either a clearance or side marker light when properly mounted.
Durable Build That Handles Everyday Use: Tough ABS Housing
Road grime and vibration can wear down weaker parts, but this one holds up thanks to its durable ABS construction. The housing keeps the bulb protected while staying compact at just 1-1/8" thick. Snap the lens in place and you’re ready to go; no special tools or sealants needed.
Consistent Power Draw That Fits Most Circuits: 0.4 Amps at 12.8V
Each light draws only 0.4 amps at 12.8V, so even with multiple units wired together, the total load stays reasonable for a standard running light circuit. That means reliable brightness without overloading your system.
Direct Replacement Confidence: Cross-Compatible Fit
If you’re replacing older lights from other brands, this one matches several common part numbers—Uni Bond #ML1020R, Truck Lite #26306R, Grote #46882, Peterson #107WR, and Bargman #40-39-001—so you can swap it in knowing the size and mounting holes (2-3/4" center to center) will line up right where they should.

Much easier than other types of marker lights because of the fact there is no ground wire, just power. It made the installation process so much quicker. Great product.

Already reviewed this for the amber color lights. Same comments apply. They fit, they work, and I ordered some extra bulbs and red and amber side marker lights in case some more break in the future. I will be ready.

Theyre still on the utility trailer that I installed them on, working fine, and I am satisfied with the quality and function of the lights.

They all worked after i installed them , all 5 across the back of my trailer . I also bought led turn/stop lights and they work just fine better than the old loose bulb type. I also repainted my trailer.

product was an exact replacement for my trailer marker light. I also purchased the 3 light marker bar, which was also an exact replacement of the one used by the manufacture. etrailer made it easy to locate and the items arrived in a timely manner.

It’s is an exact replacement for my 2012 boat trailer. What is a constant is the great customer service and support that E trailer provides.

Oddly enough I was having a hard time finding these specific clearance lights for the trailer of my bass boat. Was happy to find them here, with a fair price, and quickly shipped. Emails to let me know of every update. This was my first experience with etrailer, but I suspect it will not be my last.

Pretty good, easy to install and works. Used these on my car hauler for safety markers at the rear. Do just fine and inexpensive.

Found the lights I was looking for at etrailer. Other sites did not have the ones I needed. Fast delivery. Email confirmation from a person at etrailer after ordering online. Email follow up after delivery. Best place to order trailer lights.

See what our Experts say about this Optronics Trailer Lights
- Replacement Trailer Clearance LED Lights with 2 3/4 Mounting Hole Spacing Yes, I have an LED replacement with a 2 3/4" mounting hole spacing. I recommend the Mini LED Clearance or Side Marker Trailer Light - Submersible - 3 Diodes - Amber Lens item # MCL85AB. This is a 3-3/16" x 1-1/16" rectangle that is waterproof. The LED trailer light functions as a clearance or side marker light.
view full answer... - How to Wire Sealed, 3-Light Truck and Trailer Identification Light Bar, # MC99RBThe Sealed, 3-Light Truck and Trailer Identification Light Bar, # MC99RB, is designed to tap into the running light circuit on the trailer wiring. If you have tail lights that have an output for an auxiliary running light, it could be attached to it. Otherwise, you will need to tap into the running light wiring that runs to one of the tail lights. Adding additional lights may cause an excessive power draw on the wiring system. This can cause the trailer lights on the trailer to not function...
view full answer... - Recommended 2-1/2" Diameter Red LED Clearance or Side Marker Trailer LightHey Eric. To get the lens off of the Optronics LED Clearance or Side Marker Trailer Light item # MCL0040RBB, you'll want to get a real small flat head screwdriver like those little sunglass ones. You'll then place it in the rectangular cutouts below the red lens shown in the pics attached below. After that you'll want to use the flat edge of the screw driver to slowly pry the lens off doing this evenly on both sides. The Optronics item # MCL0040RBB is a 2-1/2" diameter light with a red...
view full answer... - Do You Offer The Optronics MCL85AB With a Red Lens? I have a couple suggestions as the red version of the Mini LED Clearance or Side Marker Trailer Light # MCL85AB is no longer available. We have the Peterson Mini-Lite Clearance # 422600 and Optronics Mini Trailer Clearance # MC11RB lights which both share the same 2-3/4" mounting holes. These lights are all similar in design and use a single wire connection with the ground running through the mounting hardware.
view full answer... - What Would Amperage Draw be for 14 Optronics Clearance Lights MC11RBEach one of the Optronics Mini Trailer Clearance lights part # MC11RB draws .4 of an amp so if you had a total of 14 of these they would put a draw of 5.6 amps on the circuit. That's pretty reasonable for a running light circuit so you might check to see but I'd suspect you'd be fine.

Given as a refreshment gift for my elderly uncle’s trailer, it has mostly remained unused throughout the year, except for one instance when a tree branch was removed after a storm. The lights have kept their original appearance, and while the old trailer still sits dormant, the yard looks only slightly cluttered—helped by these affordable lights. Overall, a great product for the price!
