Say goodbye to dim or power-hungry lights. This 6-3/8" oval LED light uses 13 diodes to produce a smooth, bright outer band that outshines typical incandescent bulbs while drawing only 0.12 amps at 12.8V. The LEDs last up to 50 times longer, so you won’t be swapping bulbs or worrying about brittle filaments again. The amber lens gives clear visibility for signaling and marking, keeping things safe and efficient.
If your trailer ever sees rain, road spray, or a boat ramp, this light is built for it. The polycarbonate housing and lens are sonically sealed into one waterproof unit that keeps out water and debris. Because it’s fully submersible, it won’t fog up or corrode inside, even after repeated immersion. You can rely on it to stay bright and functional no matter the environment.
Mounting this light is straightforward thanks to its surface-mount design and compact 3/4" depth. It uses a 2-wire pigtail with 0.18 male bullets for easy connection—one for power, one for ground—and needs only a 1-1/2" diameter hole for wiring clearance. The mounting holes are spaced 4-5/8" center-to-center for a secure fit. Hardware isn’t included, but setup stays quick and clean with standard tools.
Beyond function, this light adds style with its bright ring pattern that gives trailers a modern glow. It’s P2 rated, meaning it provides a 90-degree total beam spread—perfect when used as either a clearance light or side marker light. The consistent illumination makes your trailer visible from the right angles while maintaining that crisp LED look that stands out day or night.
Built tough from impact-resistant polycarbonate, the housing and lens handle vibration and harsh conditions without cracking or fading. This solid construction keeps the LEDs protected while maintaining clarity over time. With reliability backed by a 3-year warranty, it’s a dependable upgrade that’s made to last through years of use on the road or at the ramp.

Today we're going to be taking a look at the Optronics Glow Light, M1LED Clearance or Side-Marker light. Normal trailer light with the smooth, bright outer band is going to serve as either a side-marker light or a clearance light. It's going to feature a sonically sealed design. It's got the waterproof housing and lens in it that is submersible. It is an LED system. LEDs are going to make great replacements for incandescent lights.
They last longer. They burn brighter. They're much more efficient. You don't have to worry about replacing bulbs and you don't have to worry about brittle filaments. This is going to contain an amber lens.
It's going to have a poly carbonate lens and housing when comes to the construction of those components. A very strong and durable design. It is a surface mount installation. It does require a hole at the mounting surface for the wiring to go through. Your mounting hardware is not included, but it's got a two mount hole design, one on each end of the housing here of the light. It's also going to feature your two wire pigtail.
It's going to provide your power and ground wires. It's going to have the 0.18 male bullets on the ends. If you want to hard wire this, those can be cut off. Then you can expose the wiring for hard wire applications. Another thing I want to mention is that there is a chrome bezel or trim ring that goes over the light to give it a nice finished look. It hides the mounting hardware.
That is sold separately. It can be found at etrailer.com with part number 00212317B. This is a P2 rated light. It's SAE and Department of Transportation compliant. We're going to take a look at some of the dimension really quick. Then we'll be able to hook it up to power so you can see it with power running to it, and in a low light condition. Overall length of the light, measuring from end to end is going to be about 6 3/8 of an inch. This right here measures about 2 inches. If we take a measurement of the depth, from the back of the housing to the outermost point of the light, we're looking at a depth of about 3/4 of an inch. If we measure back to the wiring, this area right here, that's going to give us an overall depth of about 1 inch. The mount holes on the unit, these are going to be separated on center apart from one another by 4 5/8 of an inch. The light itself, that's going to give us a measurement going this direction of about 1 11/16 of an inch. Then the light itself gives us a length measurement of about 4 1/4 inches. It's going to contain 13 diodes, or LEDs. It's going to have a power drawl at 12.8 volts of 0.12 amps. Let's go ahead and hook it up to our external power source that we can see what it looks like with some power running to it. You can see hear that the light sends out a really nice clear, consistent signal. It's going to feature that smooth, bright outer band. This light does serve as either a side-marker light or clearance light. The multi-diode design, again it's got 13 diodes or LEDs, that really helps optimize the light output for a nice clear, consistent signal. That's going to do it for today's look at the Optronics Glow Light M1LED Clearance or Side-Marker Light.

Installed on my trailer everything works great
LI got the red and amber for my trailer's side corners and they work great!
I put the red and amber lights on the side corners of my trailer and they look great.
Optronics products just feel like a good quality product. This light is no different. etrailer has great customer service, just give them a call and happy to help you place your order and also make sure you have everything you need.
Get these marker lights for my truck. They were literally the easiest thing to put on. It’s took about 15 minutes to install each one my running boards on my truck. I have order things in the past with etrailer and they are always so nice to work with.
