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.

Love how bright they are. If you are planning a surface mount, as I did, you probably won't want a pigtail. Space was at a premium and my access holes are small. I just cut the connector leaving 3 inches and tied into the existing bundles.



by:

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.

Fast shipping and great product! Exact replacement off a 2017 Skeeter fx21 bass boat



by:

Excellent product and service



by:

Same as original for my skeeter boat trailer. Price was good and shipping was quick.



by:

Everything delivered on time and complete. Heavy duty suspension kit is a must.
Took all of the guesswork out of building a trailer from scratch.

The light replacement was identical, works fine and no issues. Im very Happy.



by:

These tail lights fit and worked same as the originals. Great product.



by:

they are great! no troubles whatsoever .I have then on my boat trailer (20) on a 16 footer, even 2 clear ones for back up lights. I beat on them never even unplug them when i put it under the water to launch or land the boat ,,,,,,,,
Also on my flat bed still adding ones on it lol.



by:

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.



by:

Good looking tail lights



by:

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.

This lamp is sold in a quantity of one, as is stated in the product description.



by:

Product was just as expected. Perfect match to what I needed and came super quick.



by:

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.



by:

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



by:

The tail light description and measurements are spot-on. Plug- in worked correctly and LED lights function great. The long processing time (2 weeks) from order to delivery was unexpected.



by:



by:

The unique "glowing" running light ring is very visible and the stop/turn LEDs are very bright.
The light also came with an integrated standard connector, so no need to splice and/or purchase an additional connector.



by:

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.

  • Recommended Optronics Tail Light With 3-Prong Plug Attached
    I do have options for you. We have the Optronics # STL78RPG, which is essentially the Optronics LED Trailer Tail Light # STL78RB with a 3 prong attached. We also have the GloLight LED Trailer Tail Light # STL178RFPB. This light is identical in size to the light you mentioned, and will come with the 3 prong plug attached. The only difference is that the # STL178RFPB is a 22 diode instead of a 10 diode, so it will be a brighter light.

  • What Light Assembly Does Snap-on Reflector Ring # A78RXB Fit
    Although the Snap-on Reflector Ring, # A78RXB, will not fit the STL178 series lights like the Optronics GLOLight LED Stop/Turn/Tail Light # STL178RFPB, I do have a solution for you. Take a look at the Sealed, 6-1/2" Oval LED Trailer Stop, Turn and Tail Light, # STL78RB. This light was designed to be used with the reflector ring. I spoke with my contact at Optronics and they do not offer a reflector ring for the STL178 series lights. The lights look incredibly similar but the light you...

  • GloLight LED Tail Light Compatibility with 2018 Coachmen Clipper ST108
    The GloLight LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 22 Diodes - Oval - Red Lens # STL178RFPB is most likely a fit for your 2018 Coachmen Clipper ST108. The best way to confirm fit is to check the mounting hole locations. The mounting holes are 7 inches on center and 2-11/16 inches on center. I've attached a photo to assist. Then you can use the Snap-on Reflector Ring for STL78RB Series LED Lights - Red # A78RXB or the chrome ring # A78CB.

  • 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.

  • Replacement Light for Optronics ST70RBTK Trailer Tail Light with Mounting Bracket
    For a replacement light that is the same size as your ST70RBTK I have two options. One is the Optronics Trailer Tail Light - Stop, Turn, Tail - Submersible - Incandescent - Oval - Red Lens # ST70RB and the other is the Optronics LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 48 Diodes - Oval - Red Lens # STL70RB. The real difference here is sticking with an incandescent light or adding LED lights. Both of these lights have the same measurement of the discontinued ST70RBTK which...

  • LED Lights for 1991 Ranger Boat Trailer
    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. For the stop/turn/tail lights you can use the GloLight LED Trailer Tail Light # STL178RFPB; this is a surface mounted light that is 7-1/2" wide x 3-5/16" tall x 1-1/8" deep and has an industry-standard 3-prong plug to connect to your trailer. Then for your clearance lights you can use # MCL-91AK, which is amber and measures 2-1/2" x 1-3/16"...

  • Determining Which Taillights Fit Skeeter Boat Trailer
    The GloLight LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 22 Diodes - Oval - Red Lens # STL178RFPB you were looking at is a flush mounted light that bolts directly to your trailer, and only requires a hole for the wiring to pass through. This light is 7-1/2" wide and 3-5/16" tall with horizontal bolt holes 7" apart, and the upper and lower bolt holes are 2-11/16" apart. If this matches the lights you currently have on your Skeeter Boat trailer this would be a great replacement...

  • Parts Needed to Add Light Kit to Bike Rack
    You could use the LED kit part # 98174LED to add the lights and wiring to your bike rack and then use the bracket # BK70BB and you'd be set. You'd have to attach the brackets to the bike rack and then once installed the lighting harness would run to the trailer wiring of your vehicle that you have.

  • 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 possible...

  • Tips For Removing Old Tail Lights Installed With Rubber Grommets
    Hello Barb. Generally with that kind of light you can pry off the grommet and light with a screwdriver or plastic pry tool. A lot of times if you have access to the light from the back side they can be a lot easier to remove. Removing the grommet may reveal some mounting screws depending on what kind of light that is.
