Optronics Trailer Lights - MCL95RB

Highlights

  • Reliable In Any Weather: Sonically sealed, waterproof housing keeps water from damaging LEDs.
  • Fewer Replacements Needed: Long-lasting LEDs draw only 0.051 amps at 12.8V and never need bulb swaps.
  • Bright, Efficient Visibility: Red lens with 3 LEDs gives clear light for marking trailer edges.
  • Simple Mounting: Single-stud, 1-wire design grounds through hardware for quick setup.
  • Compact Fit Anywhere: 2-1/8" x 1-1/8" x 1-1/16" rectangle works well where space is tight.
  • Road-Safe Use: P2 rating provides 90° light spread for proper clearance or side-marker lighting.

Features to know about

Brighter, Longer-Lasting, and Efficient: LED Trailer Light

This light swaps out fragile bulbs for three long-lasting LEDs that shine bright while using less power. At 12.8V, it only draws 0.051 amps, so you get high visibility without putting a strain on your wiring. The LEDs last up to 50 times longer than incandescent bulbs, meaning no filaments to break and no bulbs to replace. It’s a clean, efficient upgrade that keeps your trailer safely lit.

Tired of Water Damage: Fully Sealed and Submersible Design

Moisture is no match for this light’s construction. The lens and housing are sonically sealed into a single waterproof unit that’s submersible, keeping out water that can corrode wiring or fry diodes. Whether you’re on wet roads or loading at the ramp, the sealed design keeps the LEDs protected and working reliably trip after trip.

Simple, Reliable Mounting: Stud-Mount with Built-In Ground

Installing this light couldn’t be easier. It mounts with a single stainless steel stud that doubles as the ground, so there’s only one wire to connect for power. No extra grounding wires or complicated hookups—just secure it with the stud and you’re done. The compact 2-1/8" long by 1-1/8" wide size tucks neatly onto the surface where you need it most.

Clear Coverage Where You Need It: P2-Rated Beam Pattern

Safety comes from being seen, and this P2-rated light delivers a focused 90-degree total beam spread—45 degrees to each side of centerline—for solid visibility straight on or at an angle. That makes it perfect as either a clearance light or a side marker light when mounted correctly. It keeps your trailer visible in low light so everyone on the road knows where you are.

Built Tough for Everyday Use: Durable Polycarbonate Lens and Housing

The red polycarbonate lens and housing aren’t just for looks—they’re built to handle bumps, vibration, and outdoor exposure without cracking or fading. It’s a rugged setup that holds up over time while still looking sharp. Once mounted, it’s one less part you’ll have to worry about replacing anytime soon.

Excellent replacement for a damaged light on my trailer. Now LED lights are an upgrade from original. Probably not feasible given a variety of applications, but a plug in tip would avoid the need for splicing the wire. Overall, a good product and easy replacement installation.

Exactly the replacement LED marker light we needed and Etrailer.com was the only place I could find it. Local stores and even online stores did not have this item, only Etrailer.com. It arrived quickly and intact.

@John Glad to hear it! What trailer do you have this guy installed on?


by:

Good service, good product.



by:

I’m using these on a boat trailer that goes into the ocean. The bulbs are sealed and the backer plate is stainless but the bolt is zinc. I swapped to a stainless nylock nut but a stainless bolt doesn’t fit the back plate.



by:

Work as expected absolutely no problems



by:

Difficult to find but not on etrailer. Fits the trailer as it should. The other clearance lights would require cutting out larger holes to fit the wires.



by:

Smaller than I needed. I'm sure they fu nction



by:

The one year later the parts are still working well



by:

Delight seemed very well made. They’re very bright. I’m very happy with my purchase.



by:

Received a large bolt. I ordered a trailer side marker light.



by:

Excellent product- exactly what I was looking for. My only recommendation is don’t use USPS - the delivery date was late by days.



by:

After a year of use I have had zero issues with my LED trailer lights. They are mounted on a farm trailer so never submerged like boat trailer lights would have been.

The lights are bright and have performed up to expectations. So much better than the older incandescents.

Very pleased.



by:

Great looking product. Very well made. Perfect fit.
Great shopping experience and fast shipping.

  • Rewiring Boat Trailer for 7-Way to Use LED Lights
    There are a number of things you will need if you want to re-wire your boat trailer to use LED lights and you should start with Junction Box # 3375601100 and 7-Way # HM20041. Keep in mind you will also need Ring Terminals # 44-5310A and Loom Clamps # A0500 For LED lights I highly recommend checking out the LED Trailer Tail Light # STL57RB (Driver's side) and # STL56RB (Passenger's side). These are submersible lights with a total of 40 diodes and have mounting holes that are 2" center to...

  • Replacement LED Trailer Lights for a 2000 Ranger R71 Boat Trailer
    I would love to help you upgrade to LED lights on your trailer but unfortunately, trailer manufacturers don't just give us a list with every light on the trailer for situations like this. If you can provide me with your full 17 digit VIN I would be more than glad to call on your behalf and see if we have the correct replacements for you.

  • Can a Stainless Steel Stud be Used as the Ground Stud on Optronics LED Clearance Light
    Using stainless steel instead of regular steel for the stud on clearance light # MCL95RB would be fine. But what you can do to help the ground is attach a wire with ring terminal between the stud and where it makes contact with the trailer frame and then run the other end of that wire to the main trailer connector ground location. And if that doesn't work then there may be something internally wrong with the light.

If that is the case, all you will need to do is replace the current lights with the LED lights.

  • Troubleshooting Trailer Running Lights Not Working
    There are a number of potential issues that could be causing your running lights not to work, but you will have to troubleshoot the problem with some detail. The first thing to do is take a look at your vehicle's owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order. If they are, in order to determine the specific problem you will need to purchase a circuit tester if you do not have one - the very handy Cordless Circuit Tester # PTW2979...

  • Adding A Third Brake Light To The Truck Cap On A 2021 Chevy Silverado
    The easiest way to get the signal for a third brake light on your truck cap is going to be by tapping into the 7-way.Using a 3rd Brake Light Logic Module # PP20-702 you'll tap into the left and right turn signals of the 7-way with the yellow wires and use the green wire to power the third brake light. The logic module will keep the third brake light from flashing when you apply your turn signals just like a converter. You'll need some extra wire # 12-1-1 and heat shrink butt connectors...

    For other options we have # MCL95AB for amber lights and # MCL95RB for red. They're still surface mounted lights but the base is included and may work for you. They're also a single wire design so they ground through the mounting hardware. If these will not work for you reply to my email with your pictures and dimensions and I'll see if I can find some that will.

  • Should Whole Light Bar # MCL97RPG be Replaced if One Light is Out
    Light # MCL95RB would not fit light bar # MCL97RPG because it does not mount appropriately to attach to the light bar base. If it were me I would replace the hole light bar. Since yours is riveted on those rivets will have to be drilled out and replaced with regular screws or bolts and nuts. All of the 2 x 1 inch lights are stud mount, see link, so keep that in mind when looking for replacements.

  • After Installing LED Trailer Tail and Clearance Lights Only Turn Signals Work
    It is not likely that the clearance lights, # MCL95RB, are the issue since they ground through the mounting hardware and only have one power wire that goes to the running light circuit. Still it is worth checking to make sure that the grounds are attached to clean and corrosion free bare metal surfaces. On the taillights, # STL70RB, the red wire is for brake lights and turn signal, black is for running lights. And white is the ground. You can't always go by color; you have to go by function....
