This red GloLight stands out with a distinctive halo band that glows as the tail light while the center LEDs handle brake and turn signals. The design makes it easy for others to see your trailer day or night and gives it a clean, modern look. With 22 diodes working together, it’s bright, efficient, and built to last longer than incandescent bulbs.
Water or weather exposure won’t slow this light down. The waterproof build makes it a great fit for trailers that see rain, boat launches, or wet roads. Its polycarbonate housing and acrylic lens are tough, sealed tight, and ready to handle harsh conditions without fogging or corrosion.
Installing this oval light is straightforward thanks to the built-in flange mounting setup. The mounting holes measure 3/4" in diameter and make for a secure surface mount installation. Just pair it with a standard 3-prong PL-3 pigtail—like the A45PB or A47PB (sold separately)—and you’re ready to wire it up without any complicated steps.
At 12.8 volts, this light draws only 0.295 amps for the tail function and 0.59 amps for brake or turn—keeping current low while giving you solid brightness where you need it most. That means less strain on your electrical system and more reliable performance every time you hit the road.
You can count on this light meeting key lighting regulations for road use. It’s DOT compliant and meets FMVSS 108 and CMVSS standards, so you know your setup stays visible, reliable, and within legal requirements wherever you travel.

Today we're reviewing part number STL111RFB from Optronics. This is a 6 1/2 inch oval glow light LED stop, turn, and tail light with a standard three prong connection, which you can see here. This is an innovative tail light that serves as the brake light, the turn signal, and the tail light. It has an outer band of red LEDs as you can see here and that's your tail light. This band of lights does get brighter when you apply your brakes. In the center you have a row of red LEDs and those will light when you apply your brakes or use your turn signal.
You also have a red polycarbonate housing and lens which are sonically sealed and water proof and a built in polycarbonate mounting flange for easy installation. This light uses surface mount technology and what that does is protect the LEDs from moisture shock and vibration and it allows for thinner construction. This light meets all the requirements for automotive lighting from the Department of Transportation. It uses, as I said, a standard three prong plug. If you don't have one you can purchase this separately from our website.
This is the Optronics right angle three wire pigtail plug, part number A47PB. Now let's see how this works. Sorry, let's do it the right way. Get that in nice and tight. Now we do have a portable power source.
We'll plug the light into that using these connectors. The black wire is for power. The red wire is your 12 volt and the white wire with the ring terminal is your ground. Remember that your ground wire should always be installed on a clean, unpainted metal surface. Now we can turn the power on, turn our overhead light off and there's your tail light.
Now this band of lights will get brighter when you apply the brakes like this and there's your center row of lights. That's your brake light and this is your turn signal. Now we can turn our overhead light back on. This light measures 6 1/2 inches from side-to-side. It's 2 and 1/8th inches tall and it's one inch deep, or thick. There's a lifetime warranty on the LEDs and a three year warranty on the housing and the wiring. That's it for part number STL111RFB, the Optronics 6 1/2 inch oval glow light LED stop, turn, and tail light.
