Optronics STL178RB GloLight Trailer Tail Light - Stop, Tail, Turn, Oval - Clear Lens Dimensional Diagram

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

Optronics Glow light back view with plug

This GloLight has a standard 3-prong plug as pictured above. The light face extends out from the flange 3/4". The built-in polycarbonate mounting flange makes it easy to install this light on your trailer. Four screws (not included) are required.


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.

Very good product. Waterproof, very bright, and I like the way the running light is around the outside of the light, and the turn and brake light is on the inside. Great way of doing things. 713184

Great product. Easy plug and play install from my previous lights. Very bright and a lot more secure than the existing lights. I ordered one thinking they were a pair? I guess that is on me, but it would be helpful if that was spelled out a little better. For sure happy with the product and I would purchase again. 650696

I had trouble trying to find this light.Then I called etrailer. The Representative really knew her stuff and found exactly what i needed. delivery was fast and the product was an exact replacement for the trailer light that broke. 514857

etrailer had a great selection of lights to choose from this model was on my new boat trailer unusual that it would go bad so fast. Had a hard time finding the exact replacement but these guys had it. Price was fair and delivery was quick. I will be purchasing more leds from them in the future 419382

Great product....I installed the light on my boat trailer and so far i haven't been disappointed. However I would recommend to the manufacturer that they need to do a better sealing the tail light so as to prevent the water from seeping into the light fixture. 402119

Couldn't find anything like this anywhere. This reverse light far outshines other 6" oval led types I've had and seen. Was rear ended recently, and the old ones of this same style were knocked out and run over. Fits my 2012 ranch hand sport series bumper. 490512

Light requires the use of a grommet to fix it into a recess. A video of how the grommet is installed & works with the light would be helpful. I spend a lot of time getting the grommet with the light to fit nicely note the hole needs to be a little bit larger than the light which is dimensioned in its description. Looks and fits great once installed properly. Nice products! 511515

Shipping was on time. Each light in own separate bag in box with tissue paper. Not just thrown in a box. Dielectric grease in each terminal. Light is insanely bright. Just what I wanted, hoping they last. Thanks Etrailer 568489

Optronics is a high quality brand. I love being able to see clearly behind me. I've backed over and into things; if I'd been able to see better, most could have been prevented. The backup lights make outstanding makeshift work lights for hooking up a trailer at night or changing a friend's flat tire. 644228

Review from a similar GloLight in Trailer Lights


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!!! 102044

Excellent product. Brightest reverse light I've seen. Installed on ranch hand bumper on 2012 f150. Customer service from etrailer was amazing! I was notified that my order may be delayed due to availability via phone and email. Was not delayed after all; was notified about the package being shipped days later and the rest is history. All over, I feel very happy with my purchase 238728

I'm only giving you a little over a good mark. Service was great delivery was great. But I'm sorry the lite is falling short of what I had hoped for. I expected a much brighter lite. with that many LED's on it.. I will say they are brighter then stock. but in dark location need as much lite can get. 572139


Comments
Because this lamp is a back-up lamp, its allowable brightness is limited by DOT regulations. A utility lamp like # BUL43CB
Optronics LED Trailer Utility Light - Submersible - 10 Diodes - Round - Clear Lens
$23.05
would be brighter, but would not be DOT compliant if used as a back-up lamp.

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. 403017

  • Which Wiring Harness Will Be Needed to Install the Optronics GloLight LED Trailer Light STL178RFPB
    The proper hardwire wiring harness for the # STL178RFPB GloLight LED trailer tail light is the # A47PB. A great and similar style side marker/clearance and turn light is the # STL78AB, this will already have the proper wires to install on your trailer. If you prefer it to be a GloLight like your tail lights we do have one from Optronics # STL111AB. The wiring harness you will need to install the GloLight # STL111AB to your trailer is part number # A47PB. Since the GloLight LED doesn't...

  • Parts Needed to Install GloLight LED Trailer Tail Light # STL178RFPB to Trailer Wiring
    Best option would be to connect the # A47PB to the wiring you have on your trailer currently so that you can easily plug in the GloLight LED Trailer Tail Light # STL178RFPB. For butt connectors you'd then want the part # DW05714. This is a really solid choice for a light and would work well for your 2018 Grand Design Solitude.

    We can get you all the lights you need though it will come in the form of different parts because there isn't a specific "kit" containing everything.

  • Troubleshooting Rear Running Lights on Re-Wired Utility Trailer
    In standard trailer wiring all clearance lights and running lights operate from the same circuit. This means that if some of the lights are working but a few do not, then those non-functioning lights may have a ground issue or other wiring problem isolated just to them. Different lights can use different ways of grounding. For example, if your side clearance lights that do work use a wired ground, but the rear lights use the light mounting studs or posts to make the ground then it is...
