Features to know about
Brighter Light with Less Power: 1-Diode LED Efficiency
This 4" x 2" rectangular LED light gives you clear, bright visibility without drawing much power. The single white diode under the amber lens uses only 0.06 amps at 12V, so it’s easy on your electrical system while staying bright enough to be seen day or night. LEDs last up to 50 times longer than old incandescent bulbs and don’t have fragile filaments to break. Once installed, you can count on steady light with no bulb swaps needed.
One Light, Two Uses: Clearance or Side Marker Function
Whether you need a clearance light or a side marker, this one can handle it. The P2-rated design produces a 90-degree beam pattern—45 degrees to either side of centerline—so it’s visible head-on but not from a full side angle. That makes it perfect for use in either role, depending on where you mount it. You get flexible placement and reliable performance that meets lighting requirements without needing extra parts.
Built-In Reflector: No Separate Mount Needed
No need to add reflectors when this light already has one built in. The reflex reflector is molded right into the amber acrylic lens, giving you extra visibility without extra steps. It keeps things simple while cutting down on hardware, saving you time and keeping your trailer looking clean and finished.
Durable Build for Everyday Use: Solid Housing and Simple Wiring
The durable black ABS base holds up against wear, while the snap-on acrylic lens stays clear and tight. It’s made for surface mounting—just line up the 3" center-to-center holes on your trailer and secure it with your own hardware. The two-wire pigtail makes wiring straightforward: one power lead and one ground wire. Hook it up, screw it down, and it’s ready to go.
Long-Term Dependability: Backed by a Lifetime LED Warranty
You shouldn’t have to think twice once the lights are installed. This Optronics LED clearance or side marker light comes with a lifetime warranty on the LEDs themselves, so you know they’re built to last through years of use without dimming or burning out. It’s a small part that makes a big difference in visibility and peace of mind every time you tow.

Did not expect to find the EXACT marker light needed. Had to fish for awhile. Original lights are 24 years old. The light purchased was EXACTLY like the originals except LED. Will likely be ordering more to replace any other of the non functioning originals.

"Almost exact" replacement for original equipment, but better.
Replacement marker lamps for my Rockwood camper trailer, the original had a white base but the black base on these look so much better and the LED shines brighter.
Replaced the two front side marker lamps and they look so good that I am considering replacing every lamp on my camper with these.

See what our Experts say about this Optronics Trailer Lights
- Are There Replacement Lenses For Optronics Trailer Clearance or Side Marker Lights Hey Johnny, Unfortunately, the replacement lenses for the Optronics Trailer Clearance or Side Marker Light w/ Reflector - Incandescent have been discontinued. Reason is the amber version of that light is already discontinued and the red version is in the midst of being discontinued. So the best I can offer are replacement lights which are similar in size, the 4" x 2" Clearance or Side Marker Trailer Light w/ Reflector - Amber # MCL0032ABB and Red # MCL0032RBB.

To replace your Bargman SAE-P-PI 68 series lights, I recommend the LED Clearance or Side Marker Trailer Light w/ Reflector item # MCL0032ABB. This light measures 4" wide by 2" tall and has mounting holes 3" on center. This light is sold individually and can be used as a clearance or side marker light. The LED Clearance or Side Marker Trailer Light item # MCL0032ABB is sold individually. It uses a simple two wire, power and ground setup to connect to your trailer. So it'll...
view full answer... - Availability of LED RV Designer Amber Clearance LightHey Ken! RV Designer only offers the # RD62ZR as an incandescent light. If you want to switch to LED I recommend the Optronics Clearance or Side Marker Trailer Light w/ Reflector # MCL0032ABB. This is a similar design measuring 4" x 2" with mounting holes 3" apart on center. Where are you headed next with your motorhome?
view full answer... - Replacement Amber and Red Running Lights for a Diamond Cargo TrailerHey Gregory, thanks for reaching out! What do you think about the Optronics Amber # MCL0032ABB and Red # MCL0032RBB lights? I'm not sure the size lights you're needing to replace on your Diamond cargo trailer, but if your current ones measure about 4" wide and 2" tall these will work (see attached photo). Are you looking to upgrade your current lights, or just needing to replace some that got damaged?
view full answer... - Can a Dedicated Amber Turn Signal be Added to Trailer TaillightsHey Corey, in order to add an amber turn signal to your trailer wiring like the part # MCL0032ABB you would need to wire in a 2-3 converter like part # C56196 so that you can have a dedicated turn signal like you would need. The part # OPT59NR has a white center light that was designed for a reverse light and there isn't an amber option similar or a version of a taillight that has a converter built into it.

When I look up pictures of the amber clearance light looks like on the 2022 Surveyor Legend 252RBLE, these are the closest options I have found: - LED Clearance or Side Marker Trailer Light w/ Reflector - 1 Diode - Black Base - Amber Lens # MCL0032ABB - LED Clearance and Side Marker Light w/ Turn and Reflector - 3 Diodes - White Base - Amber Lens # MCL32ATB If...

view full answer... - Replacement LED Marker Lights for a 2009 Timberlodge CamperThanks 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. I am slightly concerned about the width of your current light and how it fits in the groves on the side of your camper. I am going to recommend...

- Should Side Clearance Lights on Boat Trailer Act As Turn SignalsIt sounds like you have something like the Amber Lens # MCL0032ABB at the front and the Red Lens # MCL0032RBB at the back of your fenders. Normally these lights are designed to switch on and off with your headlights since they are for clearance purposes. Some trailers may be a bit more fancy and have amber lights that act as both running lights and turn signals but for a boat trailer your amber lights would more likely than not be on the same circuit as your running lights so it sounds...
view full answer... - Recommended Wiring and Lights for Utility TrailerI'm assuming you want to replace everything here so I will start off with a 4-way. I recommend using the Hopkins Endurance 4-Way Flat Trailer Wiring Harness - 30' Long # HM48265. This will give you a lot of wire to work with so you can hook up all of your lights. This uses your typical 18 gauge wire for the lights and 16 gauge for the ground. If you need additional wire you can use the # SWC97FR or # DW02923-1. You could use the Self-Stripping Connector with Waterproof Sealant - 14-18...
view full answer... - Replacing Clearance Lights On A 2020 Grand Design Imagine 2979RLI can certainly point you in the right direction. Looking at these 2020 Grand Design Imagine campers, the clearance light appears to be very similar to the Optronics # MCL0032ABB. This is a 4" long 2" tall and 1" thick amber clearance light with a black base. We also have it available with a while base # MC32AB. If you can measure one of your clearance lights, you may find that this light is virtually identical. If you find that a different size light is needed, feel free to send me some...
view full answer... - Installation of Optronics LED Clearance or Side Marker Trailer Light With Yellow and White WireI haven't seen the yellow and white before on the # MCL0032ABB but that is likely correct. Yellow is power and white is ground. The easiest way is to test it out. Since you are installing several lights I would go ahead and hook one up and make sure it works before finishing all of the others. If it does not, simply reverse the wires. It won't hurt anything if you wire it the wrong way initially.

- Replacing A Peterson 343A Side Marker LightThough we do not carry the replacement Peterson 343A light the closest replacement option that we have is The LED Clearance or Side Marker Trailer Light # MCL0032ABB.The light is 4 inches long by 2 inches tall by 1 inch thick. The distance between the mounting holes is 3 inches on center. So you will have to drill new holes for the new light. The light has a durable acrylic snap-on lens and a black ABS housing. I attached a review video link below.
