Innovative GloLight Design

Optronics GloLight STL190 Red LED Boat Trailer Combination Tail 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 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.

Bright and beautiful on vintage trailer.


so after finding out our original lights on our 69 banner travel trailer were made of un-obtainium, I gave these a shot and they worked great. the "running light" ring kinda gives it some uniqueness that goes along great with our trailer. install was a snap too.


Hi Carol. I’m very pleased with my new LED taillights! They’re the perfect replacements for the 1973 Field & Stream trailer I’ve been refurbishing. The screw holes matched perfectly with the originals and I love the low profile. Nice and bright even in the Arizona sunshine ??.


Lights still work great, they give a good look to the trailer.


The lights on line didn't seem to put out enough light. But I got them installed and they work great, and they are very visible. I rebuilt a 1963 Aristocrat 13 ft. it's called the "Lil Loafer" buy the factory and I wanted round lights to replicate the originals, these are round and almost the exact same size and it doesn't hurt my feelings at all that they are LED lights..



I still am impressed as to how noticeable they are at night. No I never regretted purchasing those lights, easy install, work great. And the trailer originally had round tail lights. I have just purchased another set of tail lights from you, just a couple days ago. Again Oval shaped 52 diode LED. These are going on a trailer that I cant find anything about, other than it was manufactured in San Jacinto California in the 1980s. I think these new lights are going to look great on there, I think original was probably an ugly square one. The trailer is a 19 ft. , 1983 Tow Lite fifth wheel single axle. I swear it was built for off road the way it looks, and it looks stock.


Purchased these for a vintage camper we are rebuilding. Haven't installed them yet, but they seem like a perfect replacement for the broken wedding cake lights that were original equipment. Still need to paint and looking forward to seeing them on our cute little camper.

Look and work great


It might be possible to give 5 stars but after purchasing all the products about a year ago, my little fiberglass trailer is not even close to being ready. All the lighting is hooked up and they all seem to work, so that's a good thing. The other products that I purchased have not been installed yet.
I would like to mention how pleased I am with e-trailer videos showing everyone how their products look and how they're used. Keep it up, I am a happy customer.



Small problem the driver side brake light only works some times, not sure all the wiring seems to be all correct. Some days It works and other days it dosen’t
They look real good on our old 1974 Shasta trailer. We are in Yellowstone National Park this Week. We are moving on to Grand Teton National Park on Saturday we will see if the driver side brake light want to work on Saturday


The lights are exactly as described. Simple three wire electrical connectors, just as shown in the etrailer video. Perfect replacements for the broken taillights on my 1984 Burro travel trailer.


Really makes the trailer stand out at night. Brake lights very visible during the day.


Better than advertised. Great service. I had a list of questions before I purchased these. A very thorough email and wiring diagram was sent to me right away. With follow up emails asking about the progress. I will never shop anywhere else. Thanks!


This product looks great. the electronics look well sealed. The plastic is not the thin cheap stuff that most lights seem to be made of. The order was processed and received quickly. No problems.


Perfect match for the 65-67 Airstream Tradewinds . Need to install with stainless steel
Screws for best flexibility


Had originally ordered a different unit, but Lori called to say they would be on backorder from the maker. She suggested these to replace units that on our 81 Burro rebuild. Great service!


Bright and very visible on my camp trailer


Great taillight.


These look great on our vintage canned ham camper, leds are so bright great product. Best company.


Works great for my vintage camper. Fast shipping. Easy to install.


Install easily, much better than original, water proof


Very good light.


Look great. Lots more light than the factory ones.


have not used product yet but received it in great shape

  • Does the Optronics GLOLight LED Stop/Turn/Tail Light # STL190RB Have Install Wiring
    You are correct, the Optronics GLOLight LED Stop/Turn/Tail Light # STL190RB that you referenced does come with wires coming out of the back of it already so a separate harness would not be needed. I attached the review you mentioned as well.

  • Is the GloLight LED Trailer Tail Light # STL190RB Sold in Pairs?
    The GloLight LED Trailer Tail Light # STL190RB that you referenced is sold in a quantity of 1. If you wanted to have 2 of them then you would need to change the quantity to 2 upon checkout.

  • Can GloLight LED Light # STL190RB be Used on RV with Separate Turn Signals from Stop Lights
    Are you absolutely sure your old taillight has a turn, stop, and running light function that is separate? Most lights we carry including the # STL190RB you mentioned have the turn and stop function on the same wire since that is the standard for trailer wiring. You really can't wire this light up to a separate circuit vehicle like yours. You'd have to use this assembly for the stop and running lights and then maybe an additional # STL190RB to wire just your turn signal to so that you...

  • Recommended Round 7" Red Trailer Tail Light with Reflector
    It sounds like you're looking for a round red taillight with 7" diameter and if that's the case we do have a few options for you such as the GloLight LED Trailer Tail Light part # STL190RB which has LEDs and a reflective center. It's a surface mount light that attaches with four screws. I have also attached for you below our full selection of taillights in this size/color.

  • Round LED Trailer Taillight Recommendation Can Be Used as Turn Signal and Stoplight
    The two light illuminations of the light part # BUL603CRB are for a lower intensity red X and a bright white. It's really ideal as a taillight and reverse light. For a similar light that's designed for stop/turn and running light we have the GloLight kit part # STL190RB.

  • Replacement Taillight Options for 1967 Airstream Caravel Trailer
    I have a solution for you, but we do not offer any vintage 575 lights. I was able to find that the 575 lights were round taillights that measured 7 inches in diameter. To replace your exisiting lights with those of the same diameter, we offer both incandescent and LED lights. Our most popular 7 inch diameter, round, red trailer taillight is the Optronics # ST90RB. This is an incandescent, sealed taillight. The three taillight options that come with LED lights are the Optronics # STL90RB,...

  • Replacement Tail Lights for Trailer
    SAE is just a term for Society of Automotive Engineers and is not indicative of the light you have on your landscape trailer. It is possible the bulb is not designed to be removed, and as such you'd need to just replace the whole light. You can do so fairly cost-effectively, and I strongly recommend going to LED lights such as the Optronics Fleet LED Trailer Tail Lights # TLL12RK or GloLight LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 32 Diodes - Round - Red Lens # STL190RB...

  • Recommended 4-Way Trailer Wiring Harness For Adding New LED Lights To Vintage Trailer
    To wire the 4 clearance lights # MCL0040ABB, license plate light # M298C, and tail lights # STL190RB to your 12' long 75" wide vintage trailer, I recommend starting the 4-Way Wishbone Trailer Wiring Harness with 42" Ground Wire # A40W42B which is 40' long meaning you will have enough extra wire to connect all of the lights you are planning on adding. The # A40W42B will install as follows: Brown wire to each of the yellow wire on each of the # MCL0040ABB, to the brown wire on the # M298C,...
