Optronics MCL36 Series LED Marker Clearance Light Dimensions

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

  • Not Getting Turn Signal Function When Using LED Bulbs On A Trailer
    LED bulbs have little resistance on their own, so when used with turn signals they can create a hyper flash situation, which is a fast flashing of the bulb. To determine if you will need a load-resistor kit like a LED Light Bulb Load-Resistor Kit # DI34ZR, you will install the bulbs and when the turn signals are activated, if the bulbs hyper flash you will need to install the load-resistor kit. This kit will prevent the turn signals from hyper flashing. You will need one kit for each LED...

  • Availability of 24V Side Marker Light
    Hey Joe; we don't have anything that matches the size and shape of the # MCL36RB in 24V. We do have the Optronics LED Trailer Clearance or Side Marker Light # MCL66R24B which is designed for 12V/24V systems you could use. Options are pretty limited for 24V since 12V is the standard.

  • How Do I Convert My Incandescent Trailer Lights to LED Lights
    Yes, you just have to remove the old lights, match the wires and mount the new ones. Please note, that it is usually not a good idea to mix LEDs and incandescent lights, so if you have have side markers or other lights on the trailer, make sure you switch those to LEDs as well. Incandescent lights draw much more amperage than LEDs do, and if they pull that current through the LED fixtures, the LEDs could burn up. We have LED side markers and clearance lights like part # MCL36AB and part...

  • Replacement Trailer Taillights for Peterson PM147
    The closest light we have to the Peterson PM147 you referenced is the Square LED Trailer Clearance, Side Marker Light with Reflector, Stud Mount, 6 Diode - Red # MCL36RB or the Wesbar Clearance Light-LED-Red with Reflex Lens and White Base # 47-222014. If you want a submersible light, I recommend the Thinline Trailer Clearance or Side Marker Light - LED - Submersible - 3 Diodes - Red # MCL67RB or the Peterson Piranha LED Trailer Clearance Light, 2 Diode - Red # 169R.

  • Amber Trailer Lights Similar to MCL-71RB
    The closest thing we have to the # MCL71RB you referenced in amber would be the Optronics # MCL36AB, which is also available in red as part # MCL36RB. The lamps are a bit smaller than the # MCL71RB at 2-7/8 by 2-1/8 inches. Optronics doesn't offer that lamp in amber as an LED version.

  • Will Non-Submersible Clearance Lights Work on a Boat Trailer?
    The Square LED Trailer Clearance Light, # MCL36RB, is non-submersible, so if it gets submerged in water, the possible damage includes short circuits, cracked lenses and burned out bulbs. This light is not sealed, and does not have a drain hole which lets water out if it does get in, like some submersible lights do.

If you want a submersible light, I recommend the Thinline Trailer Clearance or Side Marker Light - LED - Submersible - 3 Diodes - Red # MCL67RB or the Peterson Piranha LED Trailer Clearance Light, 2 Diode - Red # 169R

  • Do I Need to Do Anything Special to Convert 1979 Skylark Camper to LED Exterior Lights
    There won't be any conversion needed to go from incandescent lights to LED lights on your camper. You'll simply connect the power wires and connect the light's ground wire and you'll be good to go; you could use something like the Optronics LED Trailer Clearance or Side Marker Light w/ Reflector - 6 Diodes - Square - Red Lens # MCL36RB to replace your old red clearance lights. As long as you're replacing all of the lights on your camper with LED lights you shouldn't experience any issues...

  • Are Mounting Brackets Available for Optronics Mini LED Clearance Lights # MCL95AB and # MCL95RB
    The Optronics Mini Rectangular LED Clearance Lights, # MCL95AB and # MCL95RB, are single stud surface mount lights, so they do not have a grommet or mounting bracket available. They were designed to mount directly to an existing bracket or to the trailer frame. The closest clearance lights that we carry to the dimensions of your current lights are the Optronics Square LED Clearance Light, # MCL36AB and # MCL36RB. These are also single stud surface mount lights, but the larger size should...
