This red GloLight stands out with its unique halo ring that serves as a tail light, while the center LEDs handle brake and turn signals. Both sections brighten for braking, giving clear and crisp illumination that’s easy to see from a distance, day or night. The light uses 22 white LEDs behind a red lens, drawing only 0.295 amps for the tail light and 0.59 amps for stop and turn at 12.8 volts. It’s more efficient and durable than old incandescent bulbs, so it keeps shining strong without using much power.
Designed for use in wet or harsh conditions, this light is completely waterproof. Its sealed housing keeps out moisture so you can rely on it even when your trailer goes in and out of the water. The polycarbonate housing and acrylic lens add toughness without adding weight, making it a dependable choice for long-term exposure to rain, spray, or full submersion.
Mounting this light looks sharp and stays protected. It’s designed for a recessed setup using the A70GB grommet (sold separately), which helps seal the edges and gives a flush finish. If your trailer doesn’t have an existing cutout, you can use the BK70BB mounting bracket (sold separately) instead. The 6-7/16" width and 2-5/16" height make it an easy fit for standard oval openings, while keeping a low profile at just 15/16" thick.
This GloLight’s wiring connection is built to keep moisture out. The weathertight plug design shields your wiring from corrosion and water intrusion for consistent performance over time. To connect to your system, it uses an adapter (AL45PWTB – sold separately) that works with standard 3-prong plugs, and you can choose either a right-angle pigtail (A47PB – sold separately) or straight pigtail (A45PB – sold separately).
Every detail of this light meets DOT, FMVSS 108, and CMVSS standards so you know it’s built for real-world use and road safety. With a lifetime warranty on its LEDs, you get long-term reliability without worrying about bulb replacements or fading performance over time.

Today, we're going to be taking a look at the Optronics GloLight LED Trailer Tail Light, part number STL111RMB. Here on the back of our trailer, you can see the comparison between our old incandescent bulb on the right hand side, and our new Optronics LED light on the left. It features 22 DOT approved LED lights, and because it's LED, it's going to be more efficient, and there are no bulbs to replace. It's a 6.5 inch oval light that serves three functions. You have your brakes, and then your turn signal, and then your tail lights. As you can see, when you're running your tail lights, you have the halo effect.
When the brakes are applied, everything lights up. It features a sonically sealed waterproof housing, and fits flush with a grommet, which is not included. The grommet we recommend is part number A70GB. It comes in a quantity of one, so if you're looking to replace both tail lights, which is what we recommend, you'll need to pick up a second one. Now I'll go ahead and show you how we got it installed. First, let's go ahead and start by removing our old, incandescent bulb. You can simply use a flat head screwdriver, or you can just pry it out by hand, whichever works for you.
Also, if you're not replacing the grommet, you're going to want to leave that in place. So let's pry it out. Now, with the light out, let's go ahead and disconnect this. We're just going to take two fingers here, and just kind of work it off. Now, you'll notice that our trailer here has come with a standard molded 3 volt connection here, so in order to get it to work with our new Optronics light, we're going to use an adapter.
If you have to as well, you can use part number AL45PWTB. What that's going to do, it's just going to simply plug into our old connection, and convert it to the new connection. We'll just line it up and plug it in. Press firmly to do so. Once we've got it, we can then grab our new light. It's going to come pre-greased.
We'll line it up to where the tab clips over, and once it snaps in, we've got it. Just like that. Let's test our brake first. Good, that works. Now, let's go ahead and try the turn signal. Great. Then finally, our tail light. Perfect. Now we've got it. Now that we know that everything works, we'll just simply bundle up everything and put it in place. Perfect. If anything we're to ever happen to the LEDs, they feature a lifetime warranty. That's going to complete our look at the Optronics GloLight LED Trailer Tail Light, part number STL111RMB.
