Features to know about

Brighter and More Efficient Lighting: 22-Diode LED Power

This GloLight Halo LED trailer light packs 22 diodes that put out a crisp, bright red glow for tail, brake, and turn functions. LEDs mean you get high visibility without the power draw of old incandescent bulbs. At 12.8 volts, it only pulls 0.295 amps on tail light mode and 0.59 amps on stop/turn—super efficient but still easy to spot day or night. Plus, the LEDs are backed by a lifetime warranty, so you can count on them to last.

Built to Handle Water: Fully Sealed and Submersible Design

Moisture is no match for this light. The housing and lens are sealed as one unit, creating a waterproof barrier that won’t let water sneak in or corrode the internals. It’s rated for submersion, making it a solid choice for boat trailers or any trailer that sees wet roads or heavy rain. You won’t be chasing electrical gremlins or replacing waterlogged bulbs anymore—this one’s built to take it.

Distinctive Halo Look with Practical Function

The outer ring of this oval GloLight glows as a tail light while the center section handles the stop and turn functions. That halo-style glow gives it a clean, modern look without sacrificing clarity or safety. When braking or signaling, both sections brighten together so your intentions are clear to anyone behind you.

Clean, Flush Install: Standard Grommet Mount with PL-3 Connector

Installing this light keeps things neat and low-profile. It mounts recessed in a grommet opening using the A70GB grommet (sold separately) and connects with a standard 3-prong PL-3 plug like the A45PB or A47PB (sold separately). The overall footprint is compact—6-7/16" wide x 2-5/16" tall x 15/16" thick—and once installed it only sticks out about an inch from the surface, giving your setup a factory-finished look.

DOT Compliant for Peace of Mind

This light meets DOT, FMVSS 108, and CMVSS requirements for stop, tail, and turn functions, so you know it’s legal and road ready right out of the box. You get style, brightness, and compliance all in one package without any guesswork.

Great lights.

Easy plug and play installation. Hopefully won't have to change again as long as I own the trailer.



by:

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?



by:

Tail lights are good and etrailer is great! I had accidentally screwed something up on my initial order and etrailer customer service promptly provided grade-A support. I got everything corrected in a speedy fashion. Can't thank etrailer enough!



by:

Until you see these at night you haven't seen a trailer light, etrailer is the best to deal with period!!



by:

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!



by:

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



by:

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

After a year still working great



by:

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.



by:

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.



by:

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

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.



by:

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.



by:

Although i am new at ordering trailer parts from etrailer.com 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 etrailer.com 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 etrailer.com as such. I would suggest etrailer.com to anyone seeking parts, equipment and etc.



by:

Great price, fast service. They helped me with the shipping details. Haven’t installed it yet.

Great still working.



by:

I bought these to replace my original LED's that were failing. Easy to install. I did find the electrical plug (bought here also) was hard to plug in. I think the issue was more with the plug and trying to blindly line the pins up. The center bar of lights is the tail lights. and the outer ring is used for the brighter stop/turn, look great.



by:

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.



by:

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!!!



by:

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.



by:

works as it should



by:

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.



by:

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



by:

The boat trailer light I ordered is exactly what I ordered and it came fast easy to install works great thank you for your service



by:

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.



by:

I like these lights. They appear to be bright in the daylight. Can't ask for me. My trailer is from 1997 and they just plugged into the existing wiring.

See what our Experts say about this Optronics Trailer Lights

  • 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...

  • 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...

  • 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.

  • 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...

  • Will GloLight LED Trailer Tail Light Wire to Trailer Wires
    Hi Bill; you'll need the plug-in pigtail, but yes the GloLight LED Trailer Tail Light # STL111RB will connect to the wires on your trailer. The pigtail you'll need is the 3-Wire Pigtail for Optronics Trailer Lights # A45PB. On this pigtail the white wire is ground, black is tail light, and red is turn signal.

  • 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.

  • 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...

  • 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.

  • 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.
