This round red GloLight LED stands out with its halo-style outer ring that glows for the tail light and a center section that handles brake and turn signals. It uses 21 diodes for a solid, uniform glow that’s easy to see day or night. The light face measures 4" in diameter, housed in a durable polycarbonate body with a tinted acrylic lens. It draws just 0.145 amps for the tail light and 0.375 amps for the stop/turn light at 12.8 volts—bright, efficient, and built to last with LEDs backed by a lifetime warranty.
This light is made to handle wet conditions without missing a beat. It’s fully waterproof and submersible, making it a great fit for trailers that see boat ramps or rainy roads. The weatherproof connector keeps moisture out of the wiring, and the one-piece sealed design protects the internal circuits from corrosion or shorts. Once mounted, you can trust it to stay dry and keep working when other lights would fail.
Fitting it in is straightforward. The light installs in a recessed mount using the A45GB grommet (sold separately), creating a smooth, finished look that keeps the light protected. If you’d rather not cut into your trailer body, you can use the optional BK45BB mounting bracket along with the same grommet. The snug fit helps hold the light secure while still allowing easy replacement when needed.
The back of the light uses a sealed plug connection that keeps water out and wiring simple. It requires the AL45PWTB adapter (sold separately) to connect to standard 3-prong plugs, giving you flexibility for either straight or right-angle pigtail setups. That plug-and-play style makes for a cleaner install and dependable power delivery without worrying about loose or corroded splices.
This GloLight meets DOT, FMVSS 108, and CMVSS requirements for stop, tail, and turn use. It’s designed for long-term reliability in tough environments while keeping your trailer lighting within safety standards. The combination of efficient LEDs, sealed build, and tested compliance means it’s ready for daily use without constant maintenance or replacement hassles.

Ratings & Reviews
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.
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.
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.
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.
Excellent product. Fast delivery.
Great price and fast shipping. Lights were just as described!!
awesome led halo tail lights!
Website is awesome instructional video on each product was very hopeful In deciding which product was most suitable for me I purchased all new LED lights for my utility trailer After searching multiple different companies this one was most thorough and had the best selection Ordered multiple different products showed up at my doorstep days later
These lights are outstanding, they look amazing and have outstanding visibility in many light conditions, from the brightest of day to the darkest of night. The outer ring illumination for tail lights looks aggressive and adds style to an otherwise bland part of the trailer and because the light is so bright it commands attention. When braking or turning the center section steps the brightness up a notch to make sure people can tell without question what the driver’s intentions are. After getting a set of these for my trailer, there’s no question that I’m returning to Optronics for all my future lighting projects, from converting the tail lights on the semi tractor to this very set, to just replacement of burned out clearance lighting, Optronics has a customer for life in me
Options are always the best.
I absolutely love my new tail lights. They are extremely bright and I have recommended them to all of my friends with Jeeps!
Optronics Are The Best
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.
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.
