Optronics MC68 Series Oblong 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.

  • Replacement Trailer Clearance Lights for GloBrite 122r/122y
    The globrite 122 in red or yellow/amber are 3.75 inches by 1.70 inches from what I can find online. We do not have a direct replacement, however the closest dimension we have to replace them is 3-1/2 by 1 inch. I recommend the # MC68RB and # MC68AB. If you want to go larger, then I recommend the 4x 1-1/2 inch LED # MCL17RB and # MCL17AB.

  • Replacement Lens for Glo-Brite 122R and 122Y
    I do have an option but Glo-Brite is no longer in business so you won't be able to get any replacement parts for these lights such as lenses. The only option you have would be a full replacement for which the most similar option we offer is the Optronics Clearance or Side Marker Trailer Light part # MC68RB for red or part # MC68AB for yellow.

  • Recommended Replacement for Glo-Brite 122R and 122Y Lights
    We have lights that are similar to the Glo-Brite 122R and 122Y lights but not exact replacements. I recommend the Optronics Clearance or Side Marker Trailer Light - Incandescent - Oblong - Red Lens # MC68RB and Amber Lens # MC68AB which are 3-1/2" long x 1-1/8" wide x 1" thick. I have added links to reviews of these lights for you to take a look at.

  • Replacement Red and Amber RV/Trailer Lights For Glo Brite 122x-88 Lights
    With the Glo Brite 122 series lights being obsolete we have found the Optronics Clearance or Side Marker Trailer Light in Amber # MC68AB or Red # MC68RB are the best replacement option.

  • Replacement Lens Recommendation for a Light Stamped SAE P2 93
    The Replacement Lens part # A68RB that you referenced measures 3-1/2 inches long by 1-1/8 inches tall. If the lens you are looking to replace matches these dimensions then this would work for you. The part number for the light this lens is designed for is # MC68RB.

  • Recommended Replacement Clearance Lights In Place Of Glo-Brite 122R/122Y OEM Light
    I do have a solution for you, however Glo-Brite is no longer in business and subsequently their parts are no longer available, unfortunately. Instead, what you can use instead is the Optronics Clearance or Side Marker Trailer Light - Incandescent # MC68AB. This light measures 3-1/2" long, 1-2/8" wide, 1" thick, and is made from a durable ABS plastic. Additionally, we do also have the same light available with a red lens # MC68RB if you ever should need it. Attached are a couple of...

  • Replacement Red Light Cover Needed for 3-Bulb Clearance Light Bar
    So the number that you referenced has more to do with the tests performed on the light/lens, but I still think we have a solution for you with the Replacement Red Lens # A68RB. This is a replacement for the Optronics Clearance or Side Marker Trailer Light # MC68RB which measures 3-1/2" long x 1-1/8" wide x 1" thick. If this matches what you have then this lens should work, otherwise the only other solution we have for you would be to replace your whole like bar with something like the clearance...

  • Troubleshooting Replacement Glow-Brite 122R/122Y Bulbs
    We don't carry that manufacturer and some online research indicates they may no longer be in business which if that is the case would be why. With no markings and no way to physically test the bulb for fit, all I can offer is a replacement. Have you pulled the bulb out and looked around the base for markings? The closest dimension we have to replace them is 3-1/2 by 1 inch so I strongly recommend the # MC68RB and # MC68AB as replacement options that will work well.

  • Solution for Needing Replacement Bulb for Optronics Light MC68RB
    I checked with Optronics and the # MC68RB does not have a replaceable bulb, but considering it's relative low cost it would make the most sense to just replace the entire assembly.

  • Is the Optronics Clearance or Side Marker Trailer Light LED or Incandescent
    The Optronics Clearance or Side Marker Trailer Light # MC68RB you referenced is an incandescent trailer light with a bulb. It is a surface mounted light that is 3-1/2" long x 1-1/8" wide x 1" thick; I have added a link to a video review of this light for you to check out as well. The replacement lens for this light is the Replacement Red Lens # A68RB.

  • Availability of Replacement Red Lenses for Light Bar On Utility Trailer
    The closest individual light we have to the measurement you provided is the Optronics Oblong Trailer Clearance Light # MC68RB. This light measures 3-1/2 inches x 1-1/8 inches. However, the lens for this light is not reflective. The replacement lens for this light is part # A68RB. If you are looking to replace the entire light bar, you may like the Peterson Thin-Line Red Identification Light Bar # 136-3R. The lights on this light bar are comparable to the Optronics # MC68RB lights. These...

  • Dimension Of The Replacement Red Lens for MC68RB and MC69RB
    The dimension of the Replacement Red Lens for MC68RB and MC69RB, # A68RB, you referenced is 3-12 inches by 1-1/8 inches. This is probably the closest fit you will find for your replacement lens. If you need the entire light assembly to ensure the proper fit, I suggest the Oblong Trailer Clearance, Side Marker Light, 1 Wire - Red, # MC68RB.
