This GloLight halo LED puts out a clean, bright amber glow that’s easy to spot in any light. The outer band serves as the parking light while the center LEDs handle the turn signal, giving a crisp, modern look that’s also functional. With 22 diodes and a clear lens, the light stays sharp day or night while drawing only 0.27 amps for parking and 0.515 amps for turn at 12.8V. It’s DOT compliant and meets FMVSS 108 and CMVSS standards, so you know it delivers dependable visibility that fits safety requirements.
If your trailer ever gets wet, this light is built to handle it. The housing and lens are sealed to keep out water, making it perfect for boat trailers or anything that sees rain or road spray. The polycarbonate housing and acrylic lens resist impact and corrosion, so it stays clear and intact even after plenty of use around water.
Wiring this light couldn’t be simpler thanks to the built-in PL-3 connector that works with standard 3-prong plugs such as A45PB or A47PB (sold separately). Just plug it in, and you’re ready to go—no custom wiring or splicing needed. It runs on standard 12V DC systems, so it integrates smoothly with existing setups.
This oval light measures 6-7/16" wide by 2-5/16" tall by 1-3/4" thick, fitting neatly into a grommet mount for a clean, recessed look. It installs using a grommet (A70GB – sold separately) that holds it snugly in place. If cutting a hole isn’t ideal, you can pair it with the optional BK70BB mounting bracket instead. Either way, the result is a solid, professional-looking install that stays secure mile after mile.
You won’t be swapping bulbs any time soon. The LEDs are more efficient and durable than incandescents and come backed by a lifetime warranty. Once installed, they just keep working—bright, efficient light every time you flip on your signals or running lights.

Today were reviewing part number STL111ACB from Optronics. This is a clear 6-1/2 oval glow light. Its an LED parking light and turn signal that uses a grommet mount. It takes a standard 3-wire plug on the back, as you can see here. What you have on the front is a perimeter band of amber LEDs and that will be your parking light. Then, in the center you have a row of amber LEDs and when you use your turn signal, they will light up. This light use a surface mount technology that protects the LEDs from moisture shock, vibration, bumps and shaking, and allows for thinner construction, as you can see here.
All of the lights are enclosed in a polycarbonate clear lens and housing that are sonically sealed and waterproof. This light does need all the requirements for automotive lighting from the Department of Transportation. If you do not already have the 3-wire pigtail that's required for installation, you can get this one at etrailer.com. This is the Optronics Right Angle 3-Wire Pigtail Plug, part number A47PB. You also need a grommet for installation. If you do not already have one, you can purchase this separately at etrailer.com.
This is the Optronics Rubber Grommet for 6-1/2" Oval Lights. It's part number A70GB. It fits pretty easily over the light. That's how it looks when it's installed. If you don't have a mounting bracket and you need one, you can that also from etrailer.com.
Sold separately, this is part number BK70BB. It's the Optronics Mounting Bracket for 6-1/2" Oval Lights. It does fit over the grommet like that. I can take this off now and show you how the light works. On your 3-wire pigtail, the black wire is your parking light, the red wire is your turn signal, and the white wire is your ground. I'm going to hook those up to our portable power source.
Remember that your ground is installed on a clean, unpainted metal surface. You can mount it vertically or horizontally. I'll show it to you horizontally. We'll turn off our overhead light and I'll turn on the power for the source here, and you can see your parking light. Now, I'll show you the turn signal. Now we can turn our overhead light back on. I'm going to slip the grommet off so that I can show you the dimensions. From side to side, this light measure 6-1/2" wide, 2-1/8" tall, and it's 1" thick. There's a lifetime warranty on the LEDs and a three-year warranty on the wiring and the housing. That's it for part number STL111ACB from Optronics, the clear 6-1/2" oval glow light. .

Still great, nice and bright. They are a huge improvement over the factory incandescent signals.
