Optronics STL111AB GloLight Amber LED Trailer Combination Parking Light and Turn Light Dimensional Diagram

Innovative GloLight Design

Optronics oval Glow lights dimensions

This amber LED light serves as a trailer turn signal and parking light. 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 parking 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.

Simple Installation

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

This GloLight has a standard 3-prong plug as picture above. A 3-prong pigtail adapter (A45PB or A47PB - sold separately) is required to connect this light to your vehicle or trailer. An optional mounting bracket is also available (BK70BB - 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 (A70GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Video Transcript for Optronics GloLight Trailer Lights Manufacturer Review

Brett Johnson: (silence)The Glolight is the stunning combination of premier lighting technology, meeting world-class style and capabilities. The introduction of the Glolight series represents the first truly different approach in years to the visual presentation of stop-tail-turn lamps.Most LED lamps have hotspots or patterns of bright light. Glolight lamps are visually distinctive from other LED lamps, because their lenses diffuse the light, giving them a smooth, bright, glowing appearance.The Glolight optical technology is so different, it's patentable. And Optronics has 35 new products with Glolight technology in its pipeline, right now. Mudd: Lighting is one of the most visibly predominant features on any vehicle, and this is a completely different looking yet highly effective light. We're focused on integrating the latest technology into our manufacturing process, and these new lights clearly represent the innovative partnership between Vanguard and Optronics.

Innovation is important to Vanguard, our customers, and our industry. Robert: Glolight technology looks different because it is different. Different in its optical approach and different all the way down to the circuit boards.We designed and manufactured all of our lamps using the most advanced engineering techniques, and test them in our own world-class, state-of-the-art optical testing facility. Lamps are engineered to resist everything, from shock, to dust, to high-velocity water spray. We're committed to designing and manufacturing erosion-resistant LED lighting products.

And Glolight lamps are produced using solid state, surface-mount device, or SMD, technology.Most LED lamps sold in the heavy duty market today, use what is typically referred to as "through hole" construction. Optronics LEDs are mounted directly to the surface of the circuit board, eliminating exposure to connecting points. LED lamps with SMD technology, like Optronics' new Glolight, are so robust that they can continue to function even if their circuit board is completely submerged in water. The unique Glolight lenses and housings are made of tough polycarbonate material that is sonically welded to create an impermeable seal. Glolight lamps meet all FMVSS 108 and SAE photometric requirements for visibility and safety.

And our lamps are tested at a certified, independent laboratory.I guess it's redundant to say this, but our lamps come with a lifetime warranty. Roush: There's nothing out there that's as eye-catching and effective as these Glolight lamps. Vanguard is always drawn to component supplier products that contribute to our customers' efforts to operate more effectively and safely. Glolight lamps just look different and more noticeable. And that means better safety.

Brett Johnson: With world-class manufacturing facilities, harness making capabilities, and a global market presence, Optronics is now changing the competitive landscape in HD lighting. We always have access to a lighting manufacturer with global sophistication, fleets are enjoying increased product availability, and everyone is befitting from new, innovative technology and the industry's most competitive pricing structure. With Glolight, Optronics is sending a signal that things have changed in the HD lighting industry.

This light was a perfect replacement. I've had it a year and still going strong!


Etrailer delivered as promised. Lights are just what I needed.


Exactly as the image indicated


Great service





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.


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.


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**!


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.


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


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.


exactly the replacement I needed for my boat trailer


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.


Perfect for replacing the older lights on the trailer


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


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.


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.


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.


Excellent hi vis lighting for my traile r.


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.


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.


Great light and bright....

  • Recommended Oval Lights, Grommets, and Wiring for a BACKRACK Headache Rack for Pickup Truck
    I'd be more than happy to help! Here is what I found: Red - # STL111RB (x2) Amber - # STL111AB (x2) White - # BUL111CB (x2) PVC Grommet - # a70gb (x6) Pigtail - # A47PB or # A45PB (x6) These lights all match and measure 6-7/16" wide x 2-5/16" tall x 15/16" deep but the grommet will take up the rest of the space that you measured. Just be sure to only connect 1 of the wires for each function depending on how you're wanting it all to operate. I have attached a sample installation video...

  • Which Wiring Harness Will Be Needed to Install the Optronics GloLight LED Trailer Light STL178RFPB
    The proper hardwire wiring harness for the # STL178RFPB GloLight LED trailer tail light is the # A47PB. A great and similar style side marker/clearance and turn light is the # STL78AB, this will already have the proper wires to install on your trailer. If you prefer it to be a GloLight like your tail lights we do have one from Optronics # STL111AB. The wiring harness you will need to install the GloLight # STL111AB to your trailer is part number # A47PB. Since the GloLight LED doesn't...
