Optronics Trailer Lights - MCL55R1224B

Highlights

  • Reliable In Any Weather: Sonically sealed, waterproof housing keeps moisture out so the light stays bright.
  • Fewer Replacements Needed: LEDs last 50 times longer than bulbs and draw only 0.06 amps at 12.8V.
  • One Light, Two Uses: Works as a clearance or side marker light when properly mounted.
  • Simple Setup: Accepts the standard 2-prong plug for quick connection to your wiring.
  • Versatile Power Options: Runs on both 12V DC and 24V DC systems for easy matching.
  • Compact and Durable Build: 2" round polycarbonate housing stands up to rough use and corrosion.

Features to know about

Brighter Lighting, Lower Draw: 3-Diode LED Design

Older incandescent lights drain power and fade fast. This 2" round LED light uses three red diodes that deliver a strong, clear glow with minimal amperage—just 0.06 amps at 12.8V. It runs efficiently on both 12V DC and 24V DC systems, so you get sharp visibility without stressing your wiring. With no bulbs to replace and LEDs rated to last up to 50 times longer than incandescents, it’s a reliable upgrade that keeps shining trip after trip.

Optronics MCL55R1224B 2-inch round red LED trailer clearance and side marker light with three diodes and waterproof sealed lens.

Built to Beat Water Damage: Fully Submersible and Sealed

Moisture can ruin traditional lights, but this one-piece design is ready for anything wet. The polycarbonate housing and lens are sonically sealed into a single waterproof unit that keeps out water and corrosion. Whether you’re driving through rain or submerging at the ramp, you won’t have to worry about leaks or shorted circuits. It’s built to handle the elements and stay dependable in harsh use.

Compact Fit, Clean Mounting: Recessed Design

When space is tight or you want a clean, flush look, this recessed-mount light fits right in. It measures just 2" in diameter and 1" deep, installing neatly with a grommet (sold separately) for a smooth finish. The industry-standard two-prong plug connection makes wiring straightforward, so you can set it up quickly without extra adapters or custom brackets.

Safe Coverage Where It Counts: P2-Rated Beam Pattern

Visibility matters on every road or ramp. This P2-rated light throws a 45-degree beam to either side of centerline, giving you a total of 90 degrees of effective coverage. That makes it ideal for use as a clearance or side marker light when properly mounted, helping others spot your trailer clearly from the front or rear while you stay compliant and safe.

Perfect replacement, just like the dr ordered. They were ordered to replace side markers on enclosed motorcycle trailer. Discription of lights was spot on as usual. Great company, as I have ordered from before and always have got what I needed and received items within time given by etrailer. Great company to deal with.

Nick, If you need a 2-1/2 clearance light I would recommend part # MCL157RB. It is 2-1/2 in diameter and is 1-3/16 deep. It is also a LED light.

Happy with my product. Put in a large order and then recieve an email that there was a mix up in their invantory and one light wont be shipped for another month. Common mistake but still a pain.

See what our Experts say about this Optronics Trailer Lights

  • Availability of 2" and 4" Round Trailer Lights That Work with 12V and 24V Systems
    For a 4" round LED trailer light the closest option we have available that is compatible with 12V and 24V systems is the Peterson LumenX LED # M826R-9, which features a 4-1/4" diameter. The LED light assembly has 9 diodes for a bright light output and is made here in the USA. Then for a 2-1/2" red assembly the closest option we have is the Optronics LED # MCL55R1224B that has a diameter of right at 2". This is designed for 12V or 24V DC systems and is completely waterproof due to its sonically...

  • Availability of a 2 Inch Diameter LED Trailer Light
    We currently don't stock a 2 inch that is 11/16 inch deep. The closest we have are two and a half inch and 11/16 inch deep LED red lights: # MCL59RB # MCL57RB Another very close option would be Optronics GloLight LED # MCL155RB. It's 2 inch diameter and 3/4 inch deep. You may need # A46PB two wire pigtail for sealed trailer clearance, side marker lights.

  • 24 Volt Trailer Light Availability
    We have a couple trailer lights that are compatible with 24 volt circuits though. Check out the part # STL23R24B, # STL90R24B, # MCL55R1224B, or # SLL43AB2.

  • 2 inch 24 Volt LED Trailer Clearance Light Recommendation
    The LED Trailer Clearance/Side Marker Light # MCL55R1224B that you referenced can be powered by 24 volts. This light does not use the weather pack connectors you referenced, but a similar style of pigtail connector part # A46PB is what is used. For a grommet you would then also need the # A54GB.

  • Replacement LED Light Recommendations For Trailer
    For a grommet mount red 2 inch clearance light I recommend part # MCL55R1224B. This light uses a 2-wire pigtail, part # A46PB for installation. If you need amber, you would order part # MCL55A1224B. Installed without a grommet, these lights measure 2 inches diameter x 1 inch deep. You can use the 2 inch grommet part # A54GB for this light for a flush mount. It would require a 2-5/16 inch mounting hole. The tail lights I recommend are the Optronics GLOLight LED Stop/Turn/Tail Light, part...

  • Tail Lights and Clearance Lights that Can be Used on Both a 12 Volt System and 24 Volt System
    For a tail light that can run off of 12 volt or 24 volt systems you can use Transit tail light # STL90R24B. For clearance lights you can use # MCL55A1224B for an amber light that works with 12 and 24 volt systems or # MCL55R1224B for a red light. For these lights use pigtail # A46PB and grommet # A54GB. Or for surface mount clearance/marker lights that are 12-24 volt compatible you can use # MCL66A24B for amber and # MCL66R24B for red.

  • Are There 24 Volt Red and Amber Trailer Clearance Lights
    There are round clearance lights (marker lights) that are 24 volt compatible, but the closest in diameter we have to what you are looking for is 2 inch diameter lights: - LED Trailer Clearance or Side Marker Light - Red Lens # MCL55R1224B - LED Trailer Clearance or Side Marker Light - Amber Lens # MCL55A1224B - 2" Round Grommet - Flush Mount # A54GB - Right Angle 2-Wire Pigtail # A46PB Those are flush-mounted lights but there are also 24 volt surface-mounted lights: - Optronics Thinline...

  • Where to Find 2" Trailer Clearance Lights
    All of our clearance lights have their own wiring so you'll need to do some splicing on your end to get all of the lights to properly function. If you're needing red 2" clearance lights you can use the part # MCL55R1224B you were looking at but if you need amber (orange) 2" clearance lights you can use the part # MCL55AB instead. To splice your wiring together you can use the Pigtail # A46PB and heat shrink butt connectors like the kit # DW05743-5 to help give you the most secure and protected...
