Innovative GloLight Design

Optronics Glow light

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.


PL-3 Wiring Connection

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

This GloLight has a standard 3-prong plug as pictured 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 (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.

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.

GloLight LED Trailer Tail Light - Stop,Turn,Tail - Submersible - 21 Diodes - Round - Clear Lens - STL101RCB

Average Customer Rating:  4.8 out of 5 stars   (1154 Customer Reviews)

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!

I ordered LED type tail lamps for my trailer. Take NOTHING for granted! I did that and received two tail lamps with no wiring, no plug-in connecter. Also no way in which to mount these lights. Needed was a rubber, round mounting that I have since ordered along with the needed connector plugs. Had the sales person asked a few questions this second parts order could have been avoided.


Comments
Curt, thank you for your review. This lights are not sold with the rubber grommet or pigtail. The grommet is part # A45GB
Rubber Grommet for 4" Round Trailer Lights - PVC
$5.80
and the pigtail would be part # A45PB
3-Wire Pigtail for Optronics Trailer Lights - 3-Prong PL-3 Plug - 10" Lead
$4.55
or part # A47PB
Right Angle 3-Wire Pigtail for Optronics Trailer Lights - 3-Prong PL-3 Plug - 10" Lead
$5.17

Had the lights on my semi trailer for a year no problems look great ! I had a few people ask where I got them I did not hesitate to tell them !
John - 03/20/2018

I would echo what another reviewer wrote about quality control. When I micro analyze it you can see many fine scratches/imperfections on the red plastic which sits under the clear lens. No one should ever be that close to it to notice but they are there. I just hope the clear lens itself doesn't attract scratches easy but time will tell..... The good thing about these are that they create visual interest and change the look of the trailer for the better. Day time visibility is increased 1000x vs the faded old single incandescent lights I had. Obviously great at night as well. I ordered the corresponding rubber surrounds but couldn't get them to fit. Off the trailer they fit like a glove but the combo proved just a bit too thick in the trailer cutout. Of course it is freezing cold here, when it warms up I will heat up the surrounds to make them more plyable and try again.




by:

This is a beautiful light - can't wait to get it installed on our fiberglass egg! It's nice to have the flexibility of mounting it in the shell or the bumper as we will mount temporarily on the bumper for transport and then move to a flush mount later for the permanent installation.

These lights are fantastic and still going strong

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.

These are being installed in the trailer I pull behind my motorcycle. They broadcast a nice get your attention lighting up a brilliant turn signal light.


Comments
I love the GloLight led trailer lights. They look awesome and function perfect. I bought the trailer as a gutted shell and built it from there to a better than new trailer. Every light on the trailer had to be clear lens and have a specific look before I would purchase, and I dont have a single regret with these lights.

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.

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.

Review from a similar GloLight in Trailer Lights


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 Optronics surface mount light (STL178RK1B) was easy to install and the 22 LED diodes provide exceptional light.
The light fits snug on the trailer bracket and the foam gasket provides extra protection.

All in one and slim. Worked perfectly on flat bed trailer where there is only 3" frame to attach to.

Review from a similar GloLight in Trailer Lights


Hello, I just opened up my order and I would like to return the lights - they are all scuffed up and scratched from the poor packaging job. The rear gasket also has a tear and they look like these units were once returned for the same reason. Please send an RMA or instructions to return the units. This is really disappointing - please advise on your website if your selling new lights or used, I paid for new lights.


Comments
It is understandable to be unhappy with the condition of the lights. The lights that we ship are new and I will send this information to our shipping department. Our customer service team will reach out to assist you.

Review from a similar GloLight in Trailer Lights


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.


Comments
Still great, nice and bright. They are a huge improvement over the factory incandescent signals.

Review from a similar GloLight in Trailer Lights


Light is fine... mounting hole location was off by 1/8"... even though my trailer holes are slotted 1-1/2". Had to grind my trailer holes by hand in 90 degree heat to make your light fit... very frustrating and not cool.supposed to be a direct replacement per your own website.


Comments
Most GLOLight LED trailer lights have the mounting holes distanced at 2 inches from center to center.

Review from a similar GloLight in Trailer Lights


Very disappointed with etrailer! Whoever packed this either does not care or is clueless in shipping. They used to small of a box. The light fixture was to big for the box, it actually bowed the box outward. It was doomed before it left etrailer. Plus I was shorted on another product that I ordered. VERY DISAPPOINTED!!




by:

Review from a similar GloLight in Trailer Lights


The item I ordered came quickly and was exactly what was ordered and was an exact fit to replace the damaged light on my camper. etrailer filled my order quickly and shipped the item promptly and followed up with tracing information. I wouldn't hesitate to purchase products from them again.

Review from a similar GloLight in Trailer Lights


Reverse lights are brighter than expected and look great on my trailer. I hope these are more theft resistant than the press in lights that came with my trailer. Overall much better lights than factory. As always etrailer delivers the best!
