Older incandescent bulbs can’t match this kind of clarity or efficiency. The GloLight Uni-Lite uses white LEDs behind an amber lens to create a bright, solid panel of light that stands out with a smooth, even glow. At 12.8 volts, it draws only 0.052 amps, giving you excellent visibility with minimal power use. The two LEDs are built on a durable SMT circuit board that handles shock, heat, and vibration, so you get long-lasting performance without dealing with fragile filaments or burned-out bulbs.
If your trailer ever sees water or rough weather, this light is ready for it. The housing and lens are sonically sealed into one waterproof unit that keeps water from reaching the diodes or wiring. That sealed design makes it completely submersible, so it’s reliable for trailers that get dunked at the ramp or see heavy rain. You don’t have to worry about corrosion or flickering—just a steady, bright light every time you hook up.
Visibility isn’t just about what’s behind you—it’s also about being seen from the sides. This PC-rated light produces a 90-degree beam to either side of its centerline for a full 180 degrees of coverage. When mounted properly, it works as both a clearance and side marker light so other drivers can see your trailer from straight on or off to the side. That extra illumination adds confidence when towing at night or in low-light conditions.
Tight spaces are no problem here. Measuring just 3/4" in diameter and 7/8" deep, this recessed-mount light installs neatly into your trailer surface using the included grommet. You’ll just need a 3/4" hole for mounting. The three-wire pigtail uses 0.180 male bullet connectors for quick hookup—covering ground, tail light, and turn signal connections for a clean setup that looks good and stays secure.

Speaker 1: Today we're taking a look at the GloLight Uni-Light LED amber clearance or side marker light. This small round trailer light can function as both a clearance and side marker light when properly mounted. It also functions as a supplemental turn signal. Now the Glow Light lens creates a solid light pattern with a smooth appearance.It is sealed and waterproof when it comes with the construction which makes it completely submersible. Durable surface inaudible 00:00:30 technology when it comes to the construction of the LED circuit board. That really helps better with stand shock, moisture and vibration.
Also allows for improved heat distribution and an overall thinner construction.Now this is an LED system. LEDs make great replacements for incandescent lights. The last longer, burn brighter and they're more efficient. With LEDs you don't have to worry about replacing bulbs or worry about brittle filaments. We're looking a a durable polycarbonate housing and acrylic lens.
It's a recessed mount installation with the included grommet.Your installation area requires a 3/4 inch diameter hole. Three wire pigtail which includes your power lead, ground wire and the supplemental turn signal. So the wire leads come with the .180 male bullets on them. If you don't want those you can actually cut those off, strip back the wiring and hard-wire if needed. It is Department of Transportation compliant.It's PC rated.
Internally it has two diodes. The overall dimensions, it's a 3/4 inch diameter light that measures about 7/8 inch deep. A power drill at 1.8 volts is 0.52 amps. And we're going to go and hook it up to power. That way you can see what it looks like with power running to it.
The white wire is our ground wire.The black wire is for the power and then red is for that supplemental turn signal function. So I'll go through it with the overhead lights on. So you can see how that signal output increases a little bit when that turn signal's activated. We'll turn the lights off so you can see it in a low light setting. It sends out a very bright consistent signal.Again, internally it has two diodes so the multi diode design really helps to optimize the overall light output. When we activate our turn signals you can see how that signal output increases which definitely makes it more visible indicating the turn signal function.Optronics also puts a lifetime warranty on their LEDs. That's going to do it for today's look at the Optronics GloLight Uni-Light LED amber clearance or side marker light.

I mean I'm staring at the photo and can't tell! It looks great. How long have you had your RV for?
