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.

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 (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.

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


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.


They work as described. I do not like getting requests for follow up ratings.


They seem to be a quality product. Very bright with just the tail lights on.


Put the STL111RB lights on my boat trailer a year ago, still working GREAT!!! In and out of Florida gulf coast saltwater at least once a week.

These lights will probably outlast the trailer they are on.



Two years of salt water use!! STL111RB lights still working great on my boat trailer.


Easy ordering. Very quick delivery! Got the exact light that I wanted.


I like the look of the Glo edge when lights are on. Haven't driven behind my box truck to see how bright they are, but definitely can't walk behind and look at them for very long. I can easily tell when my brake lights are on when I pass road signs and they light up the back of them. You could see my old lights in the signs, just not as obvious.


Peterson trailer lights started cross feeding between 1157 incandescent brake and taillights. After checking all wire splices and cleaning trailer to tow vehicle plug connection, the problem persisted. It wasn't horrendous but still bugged me; so I tried Optronics LED's. No cross feed with the LED's, and to my eye the LED's are brighter in direct comparison with 1157 still mounted in the lower position.


Great lights. I get asked about them everywhere I go. Super bright and being led they are have very low amp draw. I led a small caravan once in heavy rain. Those that were behind me could not believe how well my trailer lights blasted through the rain.


These lights are pretty impressive for trailer lights. I would be lying if I said I didn't consider putting a pair of them on my truck. The appearance is excellent, function is excellent, and I am overall very pleased with these lights. I installed them on my flatbed and livestock trailers - both look phenomenal but the vertical mount on the livestock trailer is most impressive. Installation was a snap with the new rubber bushings (purchased from etrailer for less than $1/each). You just can't go wrong for this price. I haven't seen STT lights I have liked as well as these.

As far as the shipping goes, I live in West Central Illinois and these items arrived in less than 24 hours with the standard shipping. You cannot, and I mean cannot, beat etrailer for customer-centered service. OUTSTANDING!!!


I have been wanting to replace my taillights with these for some time. Extremely bright even during the day. The glow ring is very impressive. This light should increase the safety of my trailer from other drivers. Braking and signaling increased and looks very professional.


Although i am new at ordering trailer parts from I find their merchandise of good quality. All orders have been processed fast and sent out right away. I have spoken a couple times to the staff at and they are very helpful in locating your parts for your trailer and equipment as well. I bought a couple trailer tailights that are just like the originals and they fit perfectly just like the old ones. I will continue to buy from as such. I would suggest to anyone seeking parts, equipment and etc.


Great service like always from etrailer. Lights were exactly as described on the site. I haven't put them on yet but will be going on a Eby horse trailer in the spring when the snow melts.


Everything works great was exactly as pictured in website made a big difference in seeing my trailer at night had to return sunlights the return policy is great I would go back again in order more parts from etrailer


Really nice light that stands out from the rest. Way brighter than my original trailer lights ever were! Easy install, great fit, and fast shipping. I’m an e trailer customer for life!


Great light and bright....


My new tail lights were delivered and as described thank you



After a year still working great


Great Prices, easy replacement for existing halogen boat trailer lights. These won't pop under early and late season cold water submersion.


Good fit/replacement.


Excellent lights. Give a distinctive look and are much brighter in running light mode. Since the running and brake/turn functions of the light are separate discrete lighting areas, the contrast between the two is also improved. Highly recommended!


It's a big upgrade from before LED. It's super bright! Highly recommend replacing the older light bulb style.


have had many people ask me where to buy these. So I steered them right to



All the led trailer lights are still working great. I get lots of compliments on the halo oval LED tailbrake lamps. The only Improvement I would like to see, I think the Halo stoptail, should have a brighter Stopturn, then they have. in the daytime, if you are running the tail lights, there is not a BIG visible difference. Other than that, I am very happy with the purchase.


I ordered replacement LED lights for a trailer I have . The web site was clear and easy to navigate prices are fair and delivery was prompt. What more can I say?


These products, lights, wiring and brackets, were exactly as advertised and arrived one day earlier than expected. This is my second order with this company and we are completely satisfied with their service.


This product is superb. Sealed and thin, I'll never have to bang on my trailer lights ever again to get them working.

  • How Much Will Oval GloLight LED Trailer Tail Light Stick Out From Trailer Frame
    The GloLight LED Trailer Tail Light # STL111RB will stick out about an inch when installed. It's pretty minimal and also the standard size for this style of light.

  • Lighting Requirements for Boat Trailers for Updating to Submersible LED Lights
    For boat trailers we recommend using submersible type lights which have a drain hole to allow water to exit the fixture. We also recommend always disconnecting the trailer connector before backing the boat into the water, even if you have submersible lights. On the linked page you can view all submersible LED type grommet-mount lights that we offer. Usually a combination stop/turn/tail light like # STL111RB is employed. I also included a link to a helpful article on the lighting requirements...

  • LED Tail Light to Replace a Peterson 421 Tail Light
    I checked with Optronics and the GLOLight Trailer Tail Light # STL111RB should have the same dimensions as the Peterson 421 light. It is 6-1/2 inches across and approximately 2-1/8 inches tall. Compare the measurements to your existing Peterson lights to confirm. If the Peterson lights do not use a pigtail that plugs into the back of them then you will also need # A47PB.

  • 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...

  • Can Trailer LED Taillight be Used as Vehicle Taillight
    Trailer taillights install and wire up just like vehicle taillights. For example if you used the LED taillight part # STL111RB you'd need to use the install harness # A47PB which uses the white wire for ground, the black wire for tail light, and the red wire for stop/turn signal. For a grommet you'd then need the part # A70GB.

  • Optronics 6-1/2 by 2-1/4 Inch Oval LED GloLight, Mounting Bracket, Grommet, and Pigtail
    For Trailer Light Mounting Bracket # BK70BB you would use light # STL111RB with grommet # a70gb and wiring pigtail # A47PB. I have included links to videos of all three of these parts for you. Light # STL178RB would not fit in the mounting bracket since it has its own flange for surface mounting.

  • Availability of Oval and Round LED Lights Which Fit in Rubber Grommets
    There are both oval and round LED lights which may work for you but we do not have the dimensions of rubber grommets for specific trailer manufacturers. For an oval LED light with a grommet, the GloLight # STL111RB is 6-7/16" Wide x 2-5/16" tall and fits in grommet # A70GB. A round LED light that may work is the GloLight # MCL157RB which is 2-1/2" Diameter x 1-3/16" deep and fits in grommet # A55GB. I've added links to video reviews of each of these parts, as well as links to our pages...

  • Will Optronics Submersible LED Trailer Tail Light # STL111RB Provide Bright Light Output
    LED-type trailer lighting such as the Optronics Submersible LED Trailer Tail Light # STL111RB will provide noticeably brighter light output than typical standard incandescent units. Thanks to their superb efficiency - roughly 10 times that of incandescent bulbs - they will deliver the most light output from the available power. LEDs also last far longer and generate much less heat than standard bulbs. This light's sealed waterproof housing ensures a long service life without the need...

  • Which Oval LED Trailer Tail Light is Brightest?
    It is difficult to compare the brightness on the different LED oval tail lights. Neither Bargman nor Optronics share lumen ratings for their tail lights. So, when comparing the Bargman 48 Diode Tail Light # 47-06-404 with the Optronics 22 Diode # STL111RB, or the Optronics 10 Diode # STL72RB, you won't notice a huge difference with the naked eye. But, in most cases, the more diodes there are in an LED light, the brighter it will be. This is not always the case, but all LED tail lights...
