Optronics MC31 Series 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.

etrailer is a good outfit, items are usually in stock and ship quickly. The lamps are your standard one wire type that grounds to the skin of the trailer with the mounting screw. The lamp is a 194. The wire protrudes about 4" outside the back of the lamp. They appear to be mountable in any orientation.

Ask the Experts about this Optronics Trailer Lights

  • Measuring to Ensure Clearnace Lights Fit Yacht Club Trailer
    There is a way for you to find out if the Oblong Trailer Clearance, Side Marker Light with Reflector # MC31AB fits your 2006 Yacht Club trailer, though we do not have any parts lists for years, makes and models of trailers that would allow us to know this. Instead, you will simply need to take a measurement; Clearance Light # MC31AB is surface mounted with mounting hole spacing 3" apart on center so if your trailer has that mounting hole spacing it would work for you.

  • Clearance Light Recommendation for Trailer # MC38AB or # MC31AB
    Between the clearance lights # MC38AB and # MC31AB the difference is mainly aesthetic. I personally like the black base and rounder edges of the # MC31AB so that is what I would go with. You would need to use bolts or screws to secure the base of the light to the trailer and then pop the lens on top of it to install it.

  • How To Determine Correct Replacement Amber Lens for Optronics Clearance Light With Black Base
    So I'm confident we have the correct replacement lens for you, but the 22368-022 isn't a part number, so in order to determine the correct lens, you'll need to do some quick measuring just to make sure you get the right one. The first option is the you mentioned, the Replacement Amber Lens for MC32AB Trailer Lights # A32AB. This is a replacement for the Trailer Clearance or Side Marker Light # MC32ABB, which is a one-wire light, and the replacement lens is 4" wide x 2" tall. The...

  • Picking Out Replacement Taillight Bulbs for 1990 Jayco Popup Camper
    I looked up a few pictures of a 1990 Jayco popups and found that they all seemed to have taillights like the # 30-92-003 that you referenced. This light takes a 1157 bulb like the # A1157B for an incandescent bulb. The side clearance lights appear to be the part # MC31RB for red and # MC31AB which use 194 bulbs like the # A194B.

  • Replacement Lens for Optronics Trailer Clearance Light MC31AB
    The lens you need is # A31AB. It fits clearance light # MC31AB which is 4 inches long, 2-1/16 inches tall, and 1-3/32 inches deep overall. Optronics has an MC and MCL series but not just an M and the lens is not replaceable on the MCL version of the light so that is why # A31AB would be the correct lens.

  • Availability of a Oval Trailer Clearance Light with a Black Base
    The closest thing we have to a version of the Oval LED Trailer Clearance, Side Marker Light # MCL31RB that you referenced with a black base in an amber and red lens would be the Red Oblong Trailer Clearance, Side Marker Light # MC31RB and the Amber Oblong Trailer Clearance, Side Marker Light # MC31AB. Both these lights have black bases, but they have incandescent bulbs instead of LEDs.
