Optronics STL117 Series GloLight LED Low Profile Combination Tail Light Diagram

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 circuit board is sealed, which means that water will not damage the diodes or circuit board.

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

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.

Good product. To improve, I'd like a hard foam on the back where the bolts fit to give a pad between the light and mounting location. Also, it's too expensive. I paid $27 thinking it was for the driver's side and passenger's side (description was correct, I just didn't read it all). When the product came in I had to order the other side. If I did it all over, I'd get both sides elsewhere for the same price.

- STL117RB

Previous review was subject to troubleshooting why the lights weren't working. Problem was in the plug between the truck and the boat. The lights are fine and I'm upgrading my initial review from good to excellent. I really like the overall look and the bright light the LEDs provide.

- STL117RB

Because one my boat trailer stop/tail lights was damaged I decide to upgrade both of them from incandescent to LED. What a difference; downright dazzling! The change out was as simple as could be given that the format and wiring of the lens/lamp housing was virtually identical between old and new. So much so, in fact, that I kept the undamaged old lens and housing to use in case of an incident enroute. NOTE: I didn't use the crimped-on eye connector to ground the assembly to the mounting bolt of the housing as provided. I cut the eye off and wired directly to the coupler ground having just added a "car end" 6-pin to the boat trailer. Yes, I hate trailer lights that much!

- STL117RB

Awesome lights, Only had for one year but use the trailer regularly. Very happy with the visibility and low profile works great on my trailer.

- STL117RB

Direct fit for my damaged trailer light.

- STL117RB

I replaced my broken trailer light using etrailer.com service was great and the replacement product high quality.

- STL117RB

Terrific product.......if you are tired of dim incandescent taillights this is the answer. Very, very bright in the full sunlight...even brighter for turn & brake function. There is no excuse for anyone to confuse your intentions of braking, turning or emergency situations. Simple two wire per side butt connection.

- STL117RB

These are some very nice lights. Running lights are very sharp looking. Work perfect on a boat trailer. I never unplug them before launching and they continue to work perfectly.

- STL117RB

These lights are bright and are very visible ... love the new look on my boat trailer!!

These tail lights are nothing short of amazing!!! They are bright, and have worked flawlessly on my boat trailer getting submerged every weekend.

Extremely bright little trailer light that has so far performed flawlessly.

The lights are still working great. I like them so much that Ill probably end up buying another set of them for my other boats trailer sometime in the not too distant future.

Great lights. Fits my Ranger Trail great and light up very bright !

- STL117RB

Great products and pricing with exceptional customer service! The product fit perfectly on my trailer.

- STL117RB

Very good product, I will recommend this light to anyone who wants to upgrade a boat trailer.

- STL117RB

Absolutely love these lights. They are nice and bright and have a great look to them. They can be seen well in the bright daylight. Install was easy. As noted by other reviewers I was quite careful when tightening the nuts as the only thing that prevents the bolts from turning is plastic. Couldn't be happier!

- STL117RB

I installed the lights at full sun. And they are still bright.

- STL117RB

Amazing difference over stock 1157 bulbs-way brighter.

- STL117RB

Products are as described. Fast deliver y.

Looks great...and performs great. Would definitely recommend and purchase again.

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.

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

Review from a similar GloLight in Trailer Lights

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.

No worries
