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.

Ratings & Reviews
Very good quality, halo lightning looks fantastic. Definitely would recommend.
The boat trailer light I ordered is exactly what I ordered and it came fast easy to install works great thank you for your service
Optronics Are The Best
Replaced existing incandescent lights in an enclosed trailer. These LED’s are an excellent replacement, are highly visible, and good looking.
I use these for the front side marker/turn signals. I had to reinforce my frame to take them but it was worth it.
These GloLights are a major aesthetic upgrade to most other round-style taillights. Just make sure to get the correct back plug! "RMB" is the symmetric 3-pin and "RB" is the asymmetric 3-pin.
Easy quick process. The company I work for purchased a clement monstar end dump trailer and it came with these tail lights in my opinion they are the best they can be seen at anytime of day and in most weather and a cool design. Ever since I discovered these lights they are the only kind I use on my trailer
I have purchased scores of products online over the years, but this experience was by-far the best. Your website is well organized, well informed, and easy to navigate. The purchasing process went very smoothly, and the products that I purchased were competitively priced. The shipping and delivery was faster than estimated (and frankly, faster than I expected). The shipment arrived well packed, undamaged, and the contents were exactly as advertised. Thank you etrailer.com for a great experience...I'll be back to purchase again!
I really like these lights. I use them for my rear lighting and rear side marker/turn signals. I went out of the way to use these on my trailer which involved reinforcing the frame since I had to cut a large piece out to install them. Well worth it. They are bright and have a distinctive look.
These LED stop, turn, tail lights are an exceptional upgrade. They halo is a great feature and blinker lights are very bright! I truly believe these lights have made my unit safer!!!
Great lights, very bright. I like them because not many people have them and they're very eye catching. My only complaint, is trying to push them in place in the bumper with those rubber grommets, but that would be the case with any sealed light.
Excellent.. still super bright and working well. Your inventory is unsurpassed
Upgrading our 1998 Coleman Grandview, the old incandescent just seemed too dim.
Nice light, only suggestion would be to list some wiring options, was a bit confusing going from the old Bargman to the new LED.
But I read through the Bargman page here and got squared away.
Pic is LED before anchoring compared to the stock on the right. BIG improvement.
These are some pretty sweet lights. Very bright and attention getting. I am constantly getting compliments on them.
The High Points-
- I bought the standard 3 prong style, works just fine with a Truck-Lite plug and with a no name one I had lying around.
- When not using driving lights both the outer and inner lights flash for turn signal. Don't remember reading about that, but it's pretty sweet(at least for the people behind me!).
- All 4 arrived in excellent shape and with all lights working.
Now, for the only negative that I can come up with-
- 2 of the lights have what I think is a sliver of white plastic stuck between the outer circle and the cover. I'm guessing it's from pressing the halves together. They can't be seen until you're very close to them, but for a $28 light it's a bit disappointing for that to get past QA.
Regardless, I highly recommend these, they are very distinctive and so far I haven't seen anyone else with them. Can't wait to be able to afford 4 more!
These lights were added to my cargo trailer that I pull behind my motorcycle. These help to make sure that people see me when I am on the road. The lights were easy to install with the grommets and pigtails that I ordered at the same time. All the products worked together well and made the project easy to do. Love these lights and will buy more if needed.
Light was exactly what I needed. Came out of the box in excellent condition with grease on the connectors for easy install and water protection. Replaced my burned out light and it worked perfectly.
I upgraded the tail lights in addition to the back up lights. The old lights were incandescent bulbs and weren't really that bright. These new LED tail/brake/turn signal lights are much brighter so hopefully folks behind me will have an easier time figuring out what I'm trying to do while going down the road. Make sure you order the right pigtail connector when ordering the light! I failed to do that which slowed this project down by a few days.
These lights are exactly what I needed to fix my Mastertow dolly. Shipping was fast and the parts had the exact connectors and mounting screws to match.
I like these lights. They appear to be bright in the daylight. Can't ask for me. My trailer is from 1997 and they just plugged into the existing wiring.
Perfect
Looks fantastic
Absolutely LOVE these lights. Draws attention and I’m constantly asked “where did you get those” all the time. This was my second round of these. Thanks!

Nice product. Very bright. Definitely cooler looking than the incandescents that were originally installed.
