Optronics STL101RMB GloLight Red LED Trailer Tail Light Dimensional Diagram

Innovative GloLight Design

Optronics Glow lights lit around the edge

This red LED light serves as a trailer tail light with stop, turn, and tail functions. The light gives your truck or trailer a distinctive look that's completely street legal. This Optronics GloLight has a unique solid light pattern when lit, so your lights stand out from the rest. Optronics GloLights are a great way to add both style and value to your truck or trailer.


Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.


LEDs vs. Incandescent Lights

The long-lasting, cool-burning LEDs make this light the perfect replacement for incandescent vehicle and trailer lighting. LED lights are more efficient, use less power, and last much longer than incandescent lights.


Surface Mount Technology

The surface-mount technology used to construct these lights protects the LEDs from shock and vibration better than through-hole technology because the diodes are soldered directly to the surface of a printed circuit board instead of attached with wires that run through holes in the board. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability, and durability.


Weathertight Wiring Connection

Back of Optronics Glow light showing weatherproof 3-prong plug mount

This GloLight has a weathertight plug as pictured above. This type of connection is designed to help block out moisture. A 3-prong pigtail adapter (AL45PWTB - sold separately) is required to connect this light to your vehicle or trailer. An optional mounting bracket is also available (BK45BB - sold separately) to make it easier to mount the light on your trailer.


Recessed-Mount Light

Recessed mount light

Recessed-mount trailer lights install underneath a housing or a grommet (A45GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

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.



by:

Great price and fast shipping. Lights were just as described!!



by:

I absolutely love my new tail lights. They are extremely bright and I have recommended them to all of my friends with Jeeps!



by:

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



by:

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

etrailer does provide a wide range of products with different price points so the customer has a lot of choices to make the decision that is right for her\him. You also offer good online support documentation and your technical staff is also very helpful in helping the customer make the right choices.
Unfortunately, you left me with a very bad experience. I ordered a full set of lighting & wiring to redo our quad trailer from the 7-pin plug to reverse lights. A large order. I erroneously ordered 2 reverse\turn single lights, which is on me, so I expected a restocking fee (a little excessive, but that's the inventory business). I had to return the 2 wrong lights and order the correct one. I returned both lights, but etrailer said they only received one, which I was 99% sure I returned both. You had no interest or showed any flexibility considering maybe I was correct. This is a one year review you have asked me to submit and the light you claimed I did not return, still has not shown up in my garage. I liked dealing with you on numerous occasions, but I have taken my business elsewhere. That was a sad experience.



by:

Amazing upgrade from the old metal lights even with led replacement bulb in the metal cans. One video is the halo tail lights installed, the other is chasing a ground issue with the old lights for comparison.



by:

These lights are totally amazing, very bright and small footprint, just need a 3/4 drill bit and they fit like a glove, will buy more for other boat trailer upgrades.



by:

I have had these installed for a year now on my 14ft utility trailer. I love these lights! They are strong, durable, bright, and look so super cool at night! Most recently, last month, I trailered 1500 miles and through the mountains in West Virginia. They held up through curves and bumps and rainstorms and even dime-sized hail! I would recommend these to anyone who needs this style of light! I wish I had brackets enough to put two on each side... just so it would look extra bada**!



by:

The Igor worked great. I had a heck of a time trying to order lights for the trailer - either not getting the ones I intended getting or mismatched lights. But you came through like me a champ. Thanks.



by:

a little loose in the side marker bracket, but easily solved with a wiretie.



by:

Added Glolight LED's to my trailer. Much brighter than the factory originals. Makes launching pre sunrise much easier. You can see where you are backing up.



by:

Excellent replacement. Looks like original ones and simple to install. Tried to replace bulbs in old one's they would not hold contact and bulbs were almost as much as the replacement I saved time and anguish by just replacing the old ones



by:

Perfect for replacing the older lights on the trailer



by:

Very durable! After a year of use they as. Right as the day I installed them. Speaking of which, there was no surprises with this either.



by:

Was not happy with the packaging. GloLights were not packaged, just placed loose in the box with other items. One piece of brown paper in the box for a void filler. Lights were scratched up when arrived.



by:

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.



by:

Excellent hi vis lighting for my traile r.



by:

This one is for the “driver” side. It has the lens on the bottom for lighting the license plate. (It does not include the license plate holder. I like this one because you just push in the wires. I recommend this light.



by:

Great light and bright....

  • Weathertight Wiring Plug and Stainless Steel Bracket for 4 GloLight LED Trailer Tail Light
    There are 2 different possible connectors you can use for the wiring when it comes to the GloLight LED Trailer Tail Light # STL101RMB; the 3-Wire Pigtail # A45PMB which installs using splicing, and the Three-Wire Straight Pigtail # AL45PWTB which connects to the industry standard 3-way connector for lights. Please note that if you will be using the splicing method then you want to use heat shrink butt connectors like what comes with the kit # DW05743-10 as they will be much more effective. When...

  • Are Optronics Stop/Turn/Tail Led Lights With Clear Lens Brighter Than Lights With Red Lens
    The 4 inch trailer lights like part # STL101RMB or part # STL101RCMB contain 21 LED diodes. The # STL101RCMB will appear to be brighter due to the fact that the other light has a red lens and the light output is diffused. Both lights have the same number of diodes and feature the stop, turn, and tail light functions. When mounting these lights the rubber grommet needed is part # A45GB. Each of these lights requires the 3-wire pigtail when installing. For a straight pigtail you can...

  • Can Trailer Lights be Install on Jeep Wrangler JK Using Warrior Products Steel Tail Light Mounts

I am not sure where you would put light # MCL11AKB on those mounts you mentioned but it requires an 11/16 inch diameter hole. This last light is a clearance or side marker light. It is not DOT approved as a turn signal. Since we do not carry the mounts you are looking at you would have to go by the...

  • Tips for Installing Trailer Taillight with Grommet
    The grommet part # A45GB that you referenced is correct for the trailer taillight part # STL101RMB that you have. Grommets and lights can be difficult to install but the way to do it is install the light into the grommet first and then push the assembly into the hole. You can use hand soap on the grommet to help get it to slip into place as well.
