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.

After 1 year its holding up nice. It was a direct fit from my incandescent light. Worked well and would buy again, even though I expect it to last much longer. 514422

As per your request here is a photo of the installation of the running lights that I purchased from etrailer. I have included a photo of the original light fixtures that I replaced. The originals were proprietary to Winnebago Industries, but have not been available for some time. The top piece that the lights mount on are made of a plastic material & was molded to accept the fixtures into a small recessed area. As a consequence, I could find no replacements at the local suppliers. I found the MC68RB fixtures on your web site & felt sure that they would fit the recessed area. They did fit, & I was able to install them with some common sense adjustments to the new fixture & the area that received the fixture: 1 added another wire to provide ground for the light. 2 drilled a hole to accommodate the wires in the center of area to receive the fixture, as the original hole was set to one side. 3 mounting holes were wider than new fixture - used one of the original holes & used a self drilling screw on the other. We are happy with the installation, and in our opinion there is very little difference in appearance of the area between original & replacement provided by your company. There are at least 2 models (View & Nation) that used the original, global-bright 122R/122Y, sold between 2005 & 20013 from what I can tell. I no longer have the good camera that took the photo of the original photo. The photo of the replacement fixtures was taken by a smart phone, hence, less quality of photo. Sorry the quality is so poor. 510050

Ask the Experts about this Optronics Trailer Lights

Do you have a question about this Trailer Light?


  • 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 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.

  • 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.

  • 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.

  • Is Clearance Light # MC68RB D.O.T. Approved
  • If you look closely at the lens in the picture I attached you can see D.O.T. stamped on the on the front of it indicating that it is D.O.T. approved.

  • 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....

  • 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.

  • 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.
    view full answer...

  • 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.
