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.

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.

I have these lights on some of my trucks. They are simple and work well. I had purchased them locally but the store stopped stocking them. Tried etrailer and they had them at a good price with reasonable shipping costs. Had them in about 3 days!

I am restoring a 1969 Bethany Citation, and want to keep it as close to original as possible. These lights are the closest thing I have found. They fit the trailer perfectly and I feel much safer knowing I don't have to worry about 45 year old parts! Delivery was right on time and installation was a snap! I have already created my wish list for what to buy next!

Ask the Experts about this Optronics Trailer Lights



  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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...

  • 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.

  • 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.

  • 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.

  • Replacement Clearance Lights Needed for GLO-BRITE 122R and 122Y Lights
    From what I could find it looks like your 122R (red) and 122Y (amber) lights measure 3.75" x 1.70" x .81". We don't have any replacement lense directly for the GLO-BRITE lights but we do have some similar lights that you could use as replacements. I recommend checking out the Command LED lights # 328-K-51 for amber and # 328-K-52 for red. These measure 3-3/4" long x 1-5/8" tall x 1/2" deep and have mounting holes that are spaced 2-1/2" apart on center. Attached are links to review videos...

  • Recommended Mounting Hardware For Trailer Lights
    I recommend using self tapping screws to install the Oblong Trailer Clearance, Side Marker Light, 1 Wire - Amber # MC68AB, the Right Fender Clearance Trailer Light, Prewired - Amber and Red # BA44FNR or # BA44FNL, and the Trailer License Plate Light with Housing and Mounting Bracket - Clear Lens - Black Base # LP81BB. For these installations you can use Self-Tapping Screw - 1/4" -14 x 3/4" Long - Zinc # FA1131822, which is corrosion resistant and has a hex-washer-head less likely to strip.
