Features to know about
Simple Light Replacement: Direct Fit for Common OEM Models
When you’re dealing with older lights that have cracked lenses or burned-out bulbs, this Optronics clearance or side marker light makes the swap easy. Measuring 3-1/2" long by 1-1/8" wide and 1" thick, it mounts with 2-3/4" hole spacing and fits right in place of common models from Truck Lite (#26338Y), Grote (#45253), and Peterson (#M136A). The design is straightforward—no rewiring or tricky adapters—so it’s a clean replacement for many factory lights.
Built for Everyday Use: Durable ABS Housing with Snap-On Lens
Frequent towing or outdoor use can wear out fragile lights fast, but this one holds up. The housing is made of tough ABS plastic that resists cracking, and the amber lens snaps securely into place. If the lens ever needs to be replaced, it simply pops off for quick bulb access. The included gasket helps create a weathertight seal between the housing and your trailer surface, keeping the inside protected from dust and road spray.
Reliable Power Connection: Single-Wire Grounding Through Mounting Hardware
No need to run extra wires or figure out complex connections. This light uses a simple 1-wire hookup for power and grounds through its mounting hardware. That means fewer steps, less clutter, and fewer points of failure. It’s compatible with standard 12V DC systems and only draws 0.2 amps at 12.8V, making it efficient while still providing bright, visible illumination.
Clear Visibility Where You Need It: P2-Rated Beam Pattern
For safety on the road, this light delivers a defined beam pattern that covers 45 degrees to each side of centerline—90 degrees total. That makes it ideal for use as either a clearance light or a side marker light, depending on how you mount it. The amber color stands out well in low light conditions and helps mark your trailer’s edges for better visibility at night or in poor weather.
Quick Surface Mount Setup: Simple Installation on Any Flat Panel
Mounting this light couldn’t be easier. It’s designed for surface mounting using self-tapping screws (hardware not included) and sits low against the panel for a clean look. Once installed, you’ll have a dependable clearance or side marker light that’s compact, low-maintenance, and built to keep shining trip after trip.

Looked around a while for a replacement lens, without success, and was pleasantly surprised to find the exact one on eTrailer. Received the entire light fixture, a bonus, and at a very fair price, including the shipping charge . I'll look first at eTrailer.com in the future. Shipping was very fast and the tracking mapping app was very cool. As soon as the Polar Vortex ice and snow melts off the coach, and spring arrives, I'm sure it will pop right on.

This was to replace side marker lights on my Pleasureway van .Worked as expected but hole spacing was slightly off so minor modifications required. Material shipped promptly.
On a side issue you have got to do something about your price on Furrion stove top replacement rubber grommets. Not worth the $[XX] each. Seen other comments for same issue.

My 20 year old market light bases disintegrated on my Winnebago Rialta so I replaced them all with these side marker lights. The size was very close and I did have to make some relatively easy modifications to get them to work, but a year later they have been working great and there has been no moisture intrusion. I used white butyl tape for the seal instead of the rubber gaskets.

Was looking for replacement lights for pleasureway motorhome. I looked hi and lo over the internet and finally found them at etrailer. Placing the order was easy and user friendly. To my surprise the order was shipped the next day, in my hands within three days and installed within four days. I can't thank etrailer enough for their effort in fulfilling my order and making my repair job as painless as possible. Thanks again!

Grommet through which grounding screw passes has a small inside diameter. Had to remove the grommet in order to use mounting screws from previous light.
This may be an issue if you are buying this light as a replacement.
Otherwise, product appears to be of good quality considering the price.

I ordered this as a replacement for a broken light on my flatbed trailer. This is an exact duplicate, so I didn't have to replace all the lights to make them match. This is a high quality light, with no technical issues. I am grateful to etrailer.com for carrying them at a great price.

- 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 Light Solution for Glo Brite 122RHey Tom, we have lights that are similar to the Glo-Brite 122R light 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. Would this work for you?

Unfortunately they are not available from the manufacturer with a LED light. You can change the incandescent bulb to an LED Bulb # DI88VR. This will give you the lower power draw as well as the extended life that you get from LED's. The Glow Brite LED replacements are going to be the Optronics LED Trailer Clearance and Side Marker Light w/ Reflex Reflector # MCL44AB and...

This light is only 3/8" thick and uses an LED so there is no need to change the bulbs when they go out. It also has a 2 wire pigtail so that you will not have to modify the light to work on your Rialta. The Optronics Clearance or Side Marker Trailer Light # MC68AB that you inquired about will include a incandescent light bulb. It can be mounted on your...

The light itself including the housing measures 3-1/2 inches side to side, 1-1/8 inches top to bottom and sticks out 1 inch. Compare these measurements to the lights you have to determine if this is the correct fit.

I've attached the page links to our marker/clearance light options as well as to the oval light lens replacement options. Although lens # APL5AB is the correct style, it is not the correct size at 5-1/2 inches by 2-3/4 inches. Your best option is to replace the old light with a new one that may be a slightly different size. I recommend the Oblong Trailer Clearance, Side...

- Replacement Amber Running Light Lens For WinnebagoI do have a solution for you but I was not able to find an exact replacement for the 1996 Winnebago Rialta running light lens measurements you provided. We do carry the Peterson lens part # 136-15A that measures 3-1/2" long x 1-1/8" wide x 1" thick which is the closest to yours in measurement. I recommend to replace the light on your Winnebago with Peterson Thin Line Clearance Light part # 427400 because since the trailer is older it is probably going to be difficult to find a perfect...

- Replacement Amber Clearance Light for 2008 Bear G3 Boat Trailer I could not confirm the light installed on your 2008 Bear G3 trailer but the replacement amber light you referenced, Optronics Oblong Amber Trailer Clearance Light # MC68AB, does use a 1-wire hookup since it grounds through its mounting hardware and it is indeed a single-bulb light. If you can find a manufacturer name and part number on the base of your existing light this will help you match up the replacement. This light that we offer is an exact replacement for the following lights:...

- Recommended Replacement Clearance Lights In Place Of Glo-Brite 122R/122Y OEM LightI 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...
view full answer... - Availability of # MC68RB Trailer Clearance/Side Marker Light w/ Amber LensWe sure do. The version with the amber lens would be part # MC68AB. If you should ever need a replacement lens, they are available as part #A68AB.
view full answer... - Recommended Mounting Hardware For Trailer LightsI 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.
view full answer... - Troubleshooting Replacement Glow-Brite 122R/122Y BulbsWe 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... - Can the Lens on Optronics MC68 Series Trailer Marker Lights be RemovedThe lenses on the Optronics marker lights # MC68AB snap onto the base. Getting the lens off can be a little tricky. You can try a very small flat head screwdriver to gently pry it up but be careful not to slip and scratch the lens.
view full answer... - How Does the Oblong Trailer Clearance Light from Optronics GroundThe Oblong Trailer Clearance, Side Marker Light # MC68AB grounds through the mounting hardware. You only need to run a power wire to the unit.
view full answer... - Replacement Trailer Taillight for Glo Brite 122YWe don't carry the Glo Brite 122Y lights so we can't get the replacement lens or light. Best option we have would be a replacement light that is similar like the # MC68AB.
