Features to know about

Brighter, Longer-Lasting, and Efficient: LED Mini Clearance Light

This 3/4" round GloLight Uni-Lite puts out a bright, solid red glow that’s easy to see and uses very little power. The two white LEDs behind the red lens draw only 0.052 amps at 12.8 volts, so you get strong light output without stressing your wiring or draining your system. The LEDs last up to 50 times longer than old incandescent bulbs and never need replacing. It’s a clean, even light that looks great and stays reliable year after year.

No More Water Worries: Fully Submersible and Sealed Build

If you deal with rain, spray, or launch ramps, this light is made for it. The polycarbonate housing and acrylic lens are sonically sealed together into one waterproof unit that keeps water out completely. Because the circuit board uses surface-mount technology, it can take on vibration, shock, and moisture without failing. You can count on it to stay bright and corrosion-free even after repeated exposure to water.

Better Visibility from More Angles: PC-Rated 180-Degree Coverage

This light’s PC rating means it throws a 90-degree beam to each side of center for a full 180 degrees of coverage. When mounted correctly, it works as both a clearance light and a side marker light so your trailer can be seen clearly from the front and sides. That wide beam pattern helps others notice you sooner in low-light conditions.

Tight Spaces Made Easy: Compact Recessed Mount Design

At only 3/4" in diameter and 7/8" deep, this light tucks neatly into tight spots. It installs in a 3/4" hole using the included grommet for a clean recessed look that also protects the lens from damage. The simple two-wire pigtail—one power lead and one ground wire with 0.156" female barrels—makes wiring quick and straightforward.

Recessed mount LED trailer clearance or side marker light installed in grommet, showing flush fit design against trailer surface.

Distinctive Look with GloLight Lens

The GloLight lens creates a smooth panel of solid red light instead of visible LED points, giving your setup a more polished appearance while staying DOT compliant. It’s a small detail that gives your lighting a distinctive, finished look without adding complexity.

Video Transcript for Review of Optronics Trailer Lights - LED Clearance/Side Marker Light - MCL110RKBF

Michael: Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at the GloLite Uni-lite Mini LED clearance or side marker light. This is a three quarter inch diameter by seven-eighths inch round trailer light that can function as both a clearance light or a side marker light, depending on how you have it installed. It can work as both simultaneously if you have it installed properly, and that is because it is PC-rated, which means you'll be able to see it head-on like so, or from a 90 degree angle to give you a total 180 degrees of visibility.This is a sealed waterproof construction, so it is submersible. So, if you want to put it on your boat trailers, they'll do just fine there.

This is a red acrylic lens over top two white LEDs. It also has a durable polycarbonate housing, so it is going to last you a nice long time. With LEDs, if you're not familiar, they are a great option. They do last longer than your older style incandescent lights because they don't have the brittle filament inside that tends to break on the incandescence, so they are going to last about 50 times longer than your incandescent lights do. This one does have a lifetime warranty on the LEDs, so they are going to last you a nice long time.

Plus, they're more efficient, so you're going to get a brighter light with less power draw. So, LED is a great way to go.This does feature an LED circuit board that is constructed using the surface mount technology, so it's going to be very durable. It's going to help better withstand shock, moisture, and vibration, so it's going to hold up really well on your trailers, especially if you're taking them off road, something like that, they'll hold up well, do a good job for you. It also helps with the heat distribution, as well as making it a thinner construction. So, it's very durable, should do a good job for you.You can see, we do have this grommet here.

This is going to allow us to have this recessed mounted, so that you just have to drill a three-quarter inch hole and then slide this in. And then, it will sit there on our trailer like so. So, it'll just stick out a little bit. This does have a two wire pigtail to it, so you've got your white ground and your black power supply. Does have the 0.156 female bullet connectors to get this plugged in, so it'll plug right in to your two male bullet connectors to get right going to your trailer.This is Department of Transportation compliant, so it's going to meet all those standards, allow you to pull your trailer safely and legally.

And I think, overall, this is going to be a great option for you. It's going to provide a bright light, make sure that all of your side marker lights or tail lights are visible as you're pulling that trailer. So, that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

I like small marker lights. Easily seen without being overwhelmingly bright which can cause glare. I've had great experience with the quality of Optronics; with less expensive brands not so much.



by:

Don't let the small size fool you, these little lights are pretty bright. You need to be spot on with the diameter of hole you drill that these lights recess into.



by:

I selected these lights because of the way the light appears to glow from the entire pod rather than the individual lights of the LED chips in the other pods. They produce a nice glow pattern that is more pleasing to the eye rather than seeing the small light of the individual LED chips. I like the fact that they are sealed units and thereby resistant to the elements. I previously bought dual-chip light pods and had one chip in a couple of pods burn out, so I am trying these pods instead.



by:

I would give this product a 5-star rating but unfortunately, I have had a number of these lights burn out and they are in difficult-to-access locations which makes them a hassle replacing them when they burn out. Even though they are lifetime-guaranteed by Optronics that doesn't do anything for the annoyance factor when you see one burned out and replace it, only to have another one burn out shortly thereafter. I originally bought these lights because they guarantted for life AND were very bright, even in daytime. It seems that the older version of these lights were more dependable than what they are producing now. My suggestion is that you don't hardwire them into an application-install them using individual plugs so WHEN IT BECOMES NECESSARY to replace them you will not have to keep cutting and splicing your harness each time. Other than that, they are good lights.



by:

Great mini marker lights and sealed perfect so they don't corrode out in six months



by:

I installed GloLight Mini LED clearance lights on a flatbed I fabricated for an older GMC K3500, truck. The lights continue to function as they should. I am happy with my purchase.



by:

What I like about these are that the wires are nice and heavy gauge. It feels very well made and I'm confident it will withstand the abuse of my Baja. I use these as marker lights and turn signals. They are really bright and no issues seeing them during the day.

The barrels on the red lights were too long. We had to cut a portion of the ends to make them fit. Other than that, they worked

Bright and look good. Proflex does seem to eat the plastic ring

See what our Experts say about this Optronics Trailer Lights

  • Trailer Lights With Bullet-Style Connector
    Hi Alex; thanks for the photo and there are some trailer lights with that style of plug, which are bullet-style connectors such as # MCL110RKBF. That's a small clearance light, and honestly that bullet-style is pretty uncommon. So you may be able to replace them it just depends on the lights. You'll want to measure your lights and find ones the same size to replace them with. I have added a link below to our selection of trailer lights, and you can filter that by size to see if there...

  • What is The Difference In The Optronics 3/4" Grommet Fit LED Lights?
    The difference is the GloLight Uni-Lite Mini LED Clearance or Side Marker Light # MCL111RKPG has 2 LED diodes and male bullet connectors while the # MCL110RKBF also has 2 led diodes and female bullet connectors. The Uni-Lite LED Clearance or Side Marker Light # MCL12RKB has a single LED diode and no connectors on the end of the pigtail. So this one would need either connectors added or hardwired into your harness.
