Wet roads or boat ramps are no problem for this light. Its housing and amber lens are sonically sealed into a single, waterproof unit that’s fully submersible. That seal keeps water out so the light stays bright and dependable trip after trip. It’s built to handle tough use without moisture getting inside or corroding the bulb and connections.
This round 2-15/16" light spreads its beam 90 degrees to each side for a total of 180 degrees of visibility. When mounted properly, that wide coverage means it works both as a clearance and a side marker light. Other drivers will see it clearly from the front or from the side, helping improve safety at night or in low-light conditions.
Swapping out an old light is simple thanks to its built-in surface-mount flange and standard 2-prong plug connection. It fits using two mounting holes spaced 2-1/4" apart, so you can bolt it right on without drilling new holes. Just plug it in with an A46PB or A86PB harness (sold separately) and you’re ready to go.
Powered by a single incandescent bulb drawing only 0.2 amps at 12.8V, this light gives off a clean amber glow that’s easy to see day or night. The bulb can be replaced in seconds if it ever burns out, keeping maintenance quick and inexpensive while maintaining that warm, traditional look.
The polycarbonate housing and lens stand up to impacts, vibration, and road debris. They protect the internals from wear while staying clear and bright over time. Backed by a 3-year warranty, it’s a tough little light ready for whatever your trailer sees on the road or at the ramp.

Today we're going to be taking a look at part #MC54AB, this Optroncis Seal 2 inch round side marker and clearance light. This is pwowder coat rated so it is going to combine your clearance and side marker functions when mounted at a 45 degree angle because it produces 90 degree angle of light, left and right when mounted at that angle. It's going to contain 1 incandescent bulb. It's going to feature a nice sealed, water proof housing and lens. It's going to come with the flange that already installed on there. Again, this is completely sealed. It does have a nice tight water proof design.
The flange is going to contain three mounting holes. Those mounting holes are going to be separated, center on center by 2 and 1/4 of an inch. It's going to be the same distance between each set of holes. Your mounting hardware is not included. Here on the back side you can see the plug. This is going to accept the industry standard two prong plug.
That items wouldn't be sold separately. If you don't already have one you can find one here on our website. The overall diameter here at the base, that's going to give us a measurement of 2 15/16 of an inch. Then the depth from the front of the lens to the back of the housing, that's going to give us a measurement of 1 3/8 of an inch. This is Department of transportation compliant.
We're going to go and hook it up to our external power source. That way you can see what it look like with power running to it. I have a two prong plug today that I'm simply going to plug into the ports on the backside. Place it in there, give a good push so it seats correctly and creates a nice tight seal. You can see here that the light is seems at a really nice, strong consistent signal. It's a pretty bright light.
It's going to contain 1 incandescent bulb. Its DOT approved and again it's going to feature that nice sealed waterproof design. That's going to do it for today's review of part # MC54AB. This is the Seal 2 inch round side marker and clearance light from Optroncis. .

I A great experience. Product works as it should and Alec C. Made sure to keep me informed throughout the entire proceeds
The product was an exact fit nothing required. Simply plugged it in to the existing wires and it clipped right into the trailer opening. Still working today! excellent!!
Broke one of my warning lights and stretched out the rubber grommets. Perfect fit and matched my existing lights like nothing ever happened. Awesome price and was delivered quickly. You have a customer for life thank you.
Just what I need for my motorhome. Arrived much sooner than I expected. Installation was a snap.
I purchased this light assembly and a rubber grommet to replace the right marker light on my Karavan trailer. It fit perfectly and had the proper 2 pin connector. Ordering was easy and it arrived promptly.
Works as advertised.
Perfect fit, just like OEM
These running lights work great. I use them on my boat trailer which is exposed to a lot of salt water. No problems, for they are a sealed light. For the price I bought extras but haven't had to use them. It's been about a year now.
I really like the staff, you guys and gals rock! I have used you twice and thank you!
Fit perfectly.
Light work great!!!
I always buy from etrailer Customer service and fast delivery
Knowing that a Black trailer would be hard to see at night the following lights were added to my custom built trailer for night time safety.
1- Side mount red and yellow fender light which only works when either the brakes or turn signal are in use.
2- Front Clearance lights, which give additional lighting at night when approaching on coming vehicles.
Light was an identical replacement. No issues, great service and fast service. Will buy again from etrailer if I have to again.
In the process of detailing my 2003 motorcycle trailer to get it looking good again. Clearance lights needed replacement. The original red lights were now faded pink for goodness sake! Replaced all 20 lights with the thin-line red and amber side marker lights. Replacement couldn't be more simple; remove original lights, snap in new. Exact fit and everything worked perfectly. Now, once the new tires and wheels get here we'll be in good shape! The new lights definitely make you say, "no way that trailer's 15 years old" :-)
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 bought 5 of these amber lights for the front of my trailer, and 5 red counterparts for the back, and similar oval side lights too, to replace all of the 50-year-old corroded lights on my 1970 Shasta M1400. I am super pleased with them, as they look period-appropriate, and are very bright as well. The only issue I had was that the Shastas of that period used the aluminum skin of the trailer as the ground, so there is no "ground wire." On a couple of them, the caulking I put under the lights made the ground screw not find the metal skin to ground the circuit. So just a note to be careful when you put the caulk on the back of the light when you are installing. Make sure you don't caulk over, and thus insulate, the ground plate. Btw, this was my first purchase from etrailer.. and in the past year, I have purchased probably another $xxxx of stuff for our trailer. Great selection, great service. This website really should be your first stop when modernizing your "vintage" trailer.
High quality, inexpensive marker light. Easy to install, it happened to be in my mailbox as I was departing with the trailer so I just popped it in. Matches the OEM lights on the trailer.
Great service
Will send pics when installed...
