Water damage ruins a light fast, but this one is built to stay dry. The housing and lens are sonically sealed into one waterproof unit, keeping moisture out even when fully submerged. Whether you’re on wet roads or backing down a ramp, this sealed design protects the bulb and wiring so the light keeps working when you need it most.
If you’re swapping out old lights, this design makes it easy. The light mounts flush using the built-in flange and fits neatly into a 2-3/4" diameter hole. It accepts an industry-standard 2-prong PL-10 plug, so there’s no wiring guesswork or special adapters to hunt down. The 3-7/16" overall diameter gives it a clean, factory-style look that installs without hassle.
On trailers that see vibration, road spray, or even saltwater, durability matters. The polycarbonate lens and housing stand up to impacts and corrosion better than fragile glass options. It’s built to handle real-world use without cracking or clouding up, keeping your trailer’s lights clear and bright season after season.
This incandescent light draws just 0.2 amps at 12.8 volts while delivering solid visibility through its amber lens. The P2 rating gives a focused beam pattern visible from straight on within a 90-degree spread—ideal for use as either a clearance or side marker light. It’s DOT compliant too, so you know it meets the right standards for on-road safety.
Unlike sealed LED units, you can easily swap the incandescent bulb if it ever burns out. That means no replacing the whole fixture—just pop in a new bulb and you’re back up and running. It’s a simple setup that keeps downtime low and your trailer lights reliable.

Speaker 1: Today we're taking a look at the Optronics amber trailer clearance or side marker light.This round trailer light will serve as either a side marker light or a clearance light for your trailer. The sonically sealed waterproof housing and lens is submersible. Features and amber colored lens with the black flange. Features a polycarbonate lens in housing that's very strong and durable. And it contains one incandescent bulb.It's a recess mount installation with the built in black flange, hardware not included. This light is designed to fit into a 2-3/4 inch diameter hole, so if we place our ruler on this portion here, you can see that that's gonna give us a diameter of about 2-3/4 inches.
So you'll need that size of a cut out in order for the light to mount and in order for it to fit.It accepts an industry standard two prong PL-10 plug that is sold separately and available at etrailer.com. The light's Department of Transportation compliant and it is a P2 rated light. The actual diameter of the lens is about 2-1/2 inches. Overall diameter of the light is 3-7/16ths of an inch. Overall depth is 15/16ths of an inch deep.
But again, once it's installed into a 2-3/4 inch diameter hole, just right here from the bottom of the flange and up is the portion that'll be visible, so nice low profile design.The distance between each mounting hole on center is 2-5/8 inches. We're going to go and hook it up to power, that way you can see what it looks like with some power running to it. I do have a two prong plug right here. And so we'll go ahead and get that connected. Simply just plugs into the back of the unit.So you can see here that it sends out a nice consistent signal.
Again, it contains one incandescent bulb. Has the amber lens with the black mounting flange. When it comes to the power draw at 12.8 volts, it's 0.2 amps. That's going to do it for today's look at the Optronics amber trailer clearance or side marker light.
Ratings & Reviews
As a returning customer, I am pleased with your product's and service. The red and amber clearance lights are for my 1967 MCI Greyhound bus RV conversion.
Plug n play, easy.
Excellent product. I used these to replace my old tongue markers. I purchased the trailer back in May 2019 and the guy I bought it from never replaced it. I was happy to know that Etrailer had a similar one. Fit well, after I cleaned off the old ones and one of the screws was rusted so I had to purchase new screws. If anyone needs the info, the screws are self-tapping #10, 3/4 inches long - zinc. Etrailer has them on the site too but I couldn't wait to put these on so I got them from Lowe's. A plus, these markers come with a bulb already.
Exact replacement for the side marker lights on my boat trailer.
It was an exact match to what I needed to replace. I thought I was looking for a needle in a haystack and found exactly the needle I needed. Thank you!!
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.
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.
I'm so pleased with ETrailer because you are the only ones that carried it. Thank you so much.
Just what I need for my motorhome. Arrived much sooner than I expected. Installation was a snap.
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!!
I A great experience. Product works as it should and Alec C. Made sure to keep me informed throughout the entire proceeds
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.
Light work great!!!
I always buy from etrailer Customer service and fast delivery
Works as advertised.
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.
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" :-)
Light was an identical replacement. No issues, great service and fast service. Will buy again from etrailer if I have to again.
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 really like the staff, you guys and gals rock! I have used you twice and thank you!
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.
Good very
Worked as designed. Easy to install.
