Innovative GloLight Design

Optronics GloLight STL190 Amber LED Boat Trailer Combination Tail Light

This amber 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 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.

Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the 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.

Average Customer Rating:  4.8 out of 5 stars   (1313 Customer Reviews)

7" Diameter round. 2-Function, waterproof light acts as turn and parking light. GloLight lens creates a solid panel of light.Polycarbonate lens and housing. Surface mount with included rubber gasket. 3-Wire pigtail. Amber lens.


Excellent product with a novel feature. I have thus far used a pair in my school bus conversion project and am extremely happy with how they look. The glow ring is very visible even close in and at an angle. The flashing portion is very bright, it catches signs even a quarter of a mile away.


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.


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.


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**!


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.


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.


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


Perfect for replacing the older lights on the trailer


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.


Excellent hi vis lighting for my traile r.


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.


Great light and bright....


got these because they came up as replacement for the number of the old light that came out, these are ok but not really bright and I would have gone with a brighter unit even if I had to cut the metal out a bit to make it fit


Fast shipping and great product! Exact replacement off a 2017 Skeeter fx21 bass boat


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.


Small led, nice light


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.


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!


This is a tremendous wheel! The 6" wide wheel is rated at 2835 lbs. Remember your rig is only as good as its weakest link, so a pair of these would be good for 5670 lbs. Overkill on a 3500lbs axle? Maybe, but definitely gives peace of mind, and the price is comparable. They even ship with the high pressure metal stems installed. The offset is neutral, so the difference from a 5" is only a half inch back spacing increase. Be sure to check your clearances from hub face to frame, but my Dexter 95" axle has plenty of clearance from the 80" frame. eTrailer has been the best vendor, period! I originally needed these wheels in April 2016 to replace the truck wheels I had, but the 5-on-5" wheels were not a carried item. Within days the team added them to their product line and had them shipped.
These newer Vesper wheels are even better than the originals from 2016. Thanks eTrailer team for another great experience!


After a year of using these in the saltwater as backup lights for my boat trailer they are still going strong


Great Product, it's good quality and will fit perfectly for the trailer I use in my Air Conditioning, Heating & Refrigeration Business. The only problem is I ordered the wrong side. Wasn't sure if by the which one was the left or the right? I was looking at the trailer form the front when I determined it was the left one but it appears your suppose to look at the back of the trailer when you do that. Guess I will be ordering the otherside here shortly. Maybe I can get an exchange or if not then I will have a spare and hope if it does get broken again it's the other side. Etrailer has some really good quality stuff at a very good price. I got my hidden hitch from them at a Great Price. They even had a video that showed me how to install it. A couple of the local places here wanted 3 times the amount of what I paid to provide the hitch and install it for me. Will never go anywhere else for any trailer parts or accessories.


Great Light! Put two on the back of a toyhauler for backing up.
You will need the grommet and pigtail to do it right.
I had to cut two oval holes for mounting in trailer frame. Take your time with the layout and get the right sized hole saw, makes installation pretty easy.


I have a Triton trailer which had a blown out incandescent tail light.
I decided to upgrade all the lights to LED.
It took me only 30 minutes to change out all 13 lights. I used a little silicone spray and a small screwdriver and the old lights came right out of the rubber grommets and the new lights fit perfect.
They are really bright and makes a big difference, glad I did the upgrade!


If you’re going to sell lights you should also sell the wiring harness along with it I almost couldn’t use the lights but got lucky and found the wiring harness.

  • Surface Mounted Round LED Trailer Light With Amber Turn Signal
    There is a round LED trailer taillight similar to the Fusion LED # STL201XRFHXB that is amber and can be used with a turn signal, with the closest being the GloLight LED Trailer Turn Signal and Parking Light # STL190AB It does not have a reverse light (no round amber lights do) but is a turn signal light. It is 7 inches in diameter and a 3-wire pigtail. In regards to painting the other light, that's something I can't recommend as it may not meet legal requirements.
