Optronics MC53 Series Amber Marker Clearance Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MC53AB Review

Today were reviewing part #: MC53AB from Optronics. This is a sealed two inch round trailer clearance and side marker light. Its amber and it mounts flush, you could see right here. When its mounted properly, at a 45 degree angle, it does serve as both a clearance and a marker light. It has a heavy duty long life bulb and it measures two inches in diameter, this way, and 11 sixteenths of an inch deep. It does require a flush mount grommet.

If you do not already have one we do sell this grommet separately. Its a two inch flush mount round grommet part #: A54GB and the light simply snaps into that. Im not going to put it in all the way, but thats how it fits. Because you have the rubber grommet that makes it sealed and waterproof or at least weather resistant. It also requires a two prong plug.

If you do not already have the pigtail wiring thats required we do have this particular two wire pink tail plug that is sold separately on our website. This is part #: A46PB and your two wire simply snaps at the back of the light, like that. Im going to hook this up to a portable power source and well show you how that works. Okay, our red wire, here on the tester, Im going to connect to the white ground wire. The ground wire is white and has a ring terminal, so well put our alligator clip on there and then your 12 volt power wire is the black one.

Well connect our alligator clip to the end of that wire. Then well turn our overhead lights off, turn our power source on. Theres your side marker and clearance light. We can turn our power off, turn our lights back on. On the product page there is a list of lights that this will work as an exact replacement for.

Check the page to see if this will fit your light that you need to replace. There you have it for part #: MC53AB from Optronics, the sealed two inch round trailer clearance and side marker light. .

Ask the Experts about this Optronics Trailer Lights

  • Looking for Trailer Clearance/Marker Light to Replace Trucklite Model 10
    According to my research, I have found that the Trucklite model 10 clearance/side marker light measures 2-1/2 inches in diameter. Because the Optronics # MC53AB measures 2 inches in diameter, it would not be a good replacement. The Optronics # MC57AB, with its 2-1/2 inch diameter, would be the correct replacement. If you need a mounting grommet, it is available as part # A55GB. The two pin wiring pigtail is also available as part # A46PB.

  • Flush Mount Grommet and Wiring Pigtail for 2 Inch Clearance and Side Marker Lights
    The Sealed, 2" Round Trailer Clearance and Side Marker Light, Flush Mount - Amber # MC53AB or the LED # MCL55AB will use the 2" Round Grommet - Flush Mount - Open Back # A54GB for installation. You will also require the wiring pigtail # A46PB which will give you 6 inches lead.

  • What Is Hole Size For Mounting 2 Inch Round Trailer Lights With Rubber Grommet
    The item you selected, Sealed 2-1/2 Trailer Light, part # MC57AB, is a 2-1/2 inch light that will mount into a 3 inch hole using 2-1/2 inch grommet, part # A55GB. The hole size to mount a 2 inch round light flush mounted would be 2-5/16 inches. The grommet you would need for a 2 inch light would be 2 Inch Round Grommet, part # A54GB. If you are flush mounting your lights, the 2 inch light will sit inside the grommet. A 2 inch light similar to the one you selected is part # MC53AB. We...

  • Does Light # MCL50AB Use the Same Grommet as Light # MC53AB
    Yes, the Sealed Miro-Flex 2" Round LED Trailer Side Marker part # MCL50AB will fit in the same grommet as the Sealed 2" Round Trailer Clearance and Side Marker Light part # MC53AB as they are both exactly 2" diameter. The LED option however is 1-3/16" tall whereas the incandescent option is 11/16" tall but as you mentioned this should not be a problem. If you need a new grommet then you can use the 2" Round Grommet part # A54GB.

  • Replacement Side Marker Light and Grommet for a Trucklite Brand Grommet and Marker Light
    I went out to the warehouse and pulled grommet # A54GB and light # MC53AB. I then assemble them and the result looks exactly like your picture. I then measured the amount the lens sticks up above the grommet and came up with just under half an inch. The lens could be pressed further in. I used digital calipers to take the measurement. I also made a video showing the assembled result for you. The light takes wiring harness # A46PB if you do not already have them on your trailer.
