Optronics UCL178 Series GloLight LED Utility Light Diagram

Innovative GloLight Design

This white LED light serves as an exterior light for your trailer, RV, or other application. The light gives your RV 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 RV 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.


PL-3 Wiring Connection

Optronics PL-3 Connection

This light has an industry-standard PL-3 connection as pictured above. The light accepts a 3-prong plug (sold separately).


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.

Video Transcript for Optronics Trailer Lights - Utility Lights - UCL178RFP2B Review

Speaker 1: Today we're taking a look at the Optronics Glow Light taillight and reverse light. This waterproof light provides a red taillight, and white reverse light for your trailer. Has the glow light lens that creates a solid circle of light, with a nice smooth appearance. So the outer band glows red, and the inner area is white when you activate the reverse function of the vehicle and trailer.It's a sonically sealed, waterproof housing and lens unit that is submersible. Features durable surface mount technology. When it comes to the construction of the LED circuit board, that better withstands shock and vibration, and allows for improved heat distribution.

Now LEDs make great replacements for incandescent lights. They last longer, they burn brighter, and they're more efficient. With LEDs, you don't have to worry about replacing bulbs, and you don't have to worry about brittle filaments.We're looking a polycarbonate housing and acrylic lens. It's a surface mount installation, with the built in mounting flange. Mounting hardware not included.

And then here on the back, it accepts an industry standard three prong plug, which is sold separately. Taking a look at the overall dimensions real quick, then we'll hook it up to power, so you can see what it looks like with power running to it. Edge to edge going this direction, is about 7-1/2 inches. Edge to edge this direction is about 3-5/16. And then the overall depth, that's back to front, is about 1-1/8 inches deep.The mount holes are separated on center going this direction, by about 2-3/4 inches.

And then going this direction, they're separated on center by about seven inches, maybe 6-15/16 inches, right in that area. Alright we're going to go ahead and hook it up to power, that we can see what it looks like. So you can see here, it sends out a really nice, clear, consistent signal. This is that outer band that's red in color. And then when we activate the reverse function of the trailer, that center area will glow white.That contains a total of 22 diodes, or LEDs, so the multi diode design really helps optimize the overall light output.

Power draw at 12.8 volts, is 0.50 amps. And Optronics puts a lifetime warranty on the LEDs. That's going to do it for today's look at the Glow Light taillight and reverse light from Optronics.

I really like the bright back up lights. It does take a little extra work for the back up lights. - Sorry this pic doesn't show the backup/stop lights but this is the great little chuckwagon we put them on.

This one is for the “driver” side. It has the lens on the bottom for lighting the license plate. (It does not include the license plate holder. I like this one because you just push in the wires. I recommend this light.

The Optronics surface mount light (STL178RK1B) was easy to install and the 22 LED diodes provide exceptional light. The light fits snug on the trailer bracket and the foam gasket provides extra protection.

I have a Triton trailer which had a blown out incandescent tail light. I decided to upgrade all the lights to LED. It took me only 30 minutes to change out all 13 lights. I used a little silicone spray and a small screwdriver and the old lights came right out of the rubber grommets and the new lights fit perfect. They are really bright and makes a big difference, glad I did the upgrade!

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.

Great Light! Put two on the back of a toyhauler for backing up. You will need the grommet and pigtail to do it right. I had to cut two oval holes for mounting in trailer frame. Take your time with the layout and get the right sized hole saw, makes installation pretty easy.

Review from a similar GloLight in Trailer Lights


These are some pretty sweet lights. Very bright and attention getting. I am constantly getting compliments on them. The High Points- - I bought the standard 3 prong style, works just fine with a Truck-Lite plug and with a no name one I had lying around. - When not using driving lights both the outer and inner lights flash for turn signal. Don't remember reading about that, but it's pretty sweet(at least for the people behind me!). - All 4 arrived in excellent shape and with all lights working. Now, for the only negative that I can come up with- - 2 of the lights have what I think is a sliver of white plastic stuck between the outer circle and the cover. I'm guessing it's from pressing the halves together. They can't be seen until you're very close to them, but for a $28 light it's a bit disappointing for that to get past QA. Regardless, I highly recommend these, they are very distinctive and so far I haven't seen anyone else with them. Can't wait to be able to afford 4 more!

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.

Review from a similar GloLight in Trailer Lights


Great Product, it's good quality and will fit perfectly for the trailer I use in my Air Conditioning, Heating & Refrigeration Business. The only problem is I ordered the wrong side. Wasn't sure if by the which one was the left or the right? I was looking at the trailer form the front when I determined it was the left one but it appears your suppose to look at the back of the trailer when you do that. Guess I will be ordering the otherside here shortly. Maybe I can get an exchange or if not then I will have a spare and hope if it does get broken again it's the other side. Etrailer has some really good quality stuff at a very good price. I got my hidden hitch from them at a Great Price. They even had a video that showed me how to install it. A couple of the local places here wanted 3 times the amount of what I paid to provide the hitch and install it for me. Will never go anywhere else for any trailer parts or accessories.

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.

Still great, nice and bright. They are a huge improvement over the factory incandescent signals.

I have purchased scores of products online over the years, but this experience was by-far the best. Your website is well organized, well informed, and easy to navigate. The purchasing process went very smoothly, and the products that I purchased were competitively priced. The shipping and delivery was faster than estimated (and frankly, faster than I expected). The shipment arrived well packed, undamaged, and the contents were exactly as advertised. Thank you etrailer.com for a great experience...I'll be back to purchase again!

I really like these lights. I use them for my rear lighting and rear side marker/turn signals. I went out of the way to use these on my trailer which involved reinforcing the frame since I had to cut a large piece out to install them. Well worth it. They are bright and have a distinctive look.

Ordering From etrailer was a great Experience. Pat was very helpful over the phone when I called to ask questions about a set of lights I was interested in and even helped me place my order. Shipping was fast and everything they shipped was in flawless condition. My lights and harnesses are still going strong. Thank you!

These work great and the Glo-light looks very nice. I installed these on my tow dolly as the original LED's went bad from shorted wiring. These fit great and are excellent quality and the E-trailer team is excellent to deal with. Never an issues!

Review from a similar GloLight in Trailer Lights


I love these lights. They have the 3 pin weather tight connectors which are a plug-in-simple replacement for the OEM taillights I’m replacing. etrailer is one of the few online retailers that keeps these in stock. I would advise however, if your factory wiring isn’t in perfect condition then I would skip these and change out the factory pigtails to the standard 3 prong type and buy item #STL111RB instead. They are cheaper and easier to find while out on the road should one ever fail.

I am still very pleased with these lights. So pleased in fact, Ive been updating a lot of our equipment with Optronics marker and tail lights.

It’s just a little smaller in length but it will work. I needed that kind with the hard one piece. That way I can just screw it in. I had to find a picture of it on line, etrailer did not show that type. They only showed the one with the rubber seal with a template. Thanks Dan

Very good glow light trailer lights. I mounted them on a small 1972 Coleman VersaTrailer. Very pleased with quality and the glow light appearance. Very strong light as well.

The same applies to these lights. They burn when you hook up to the trailer and you don't need to run around and check them out.

  • Submersible Reverse Light and 7-Way Kit for Boat Trailer with 4-Way
    For a submersible reverse light we have the GloLight # UCL178RFP2B which would work great on a boat trailer. You'll need the pigtail harness part # A45CB which the white wire would get grounded to the boat trailer frame and the red wire to the reverse light circuit of the trailer. We have a great kit for adapting your trailer 4-way to a 7-way too with the part # e99011 which would be the easiest way to install the 7-way and wire in the reverse lights.

  • Troubleshooting Red Ring of GloLight LED Trailer Utility Tail Light Staying on
    Since the GloLight LED Trailer Utility Tail Light # UCL178RFP2B only has a max 0.50 amp draw I believe that you are on the right track where a little bit of power is still on the power wire and it is illuminating that ring. What would remedy this issue you are having is to install the Putco LED Light Bulb Load-Resistors # P230004A-2 on the brown wire that connects to the running light circuit. These build up resistance so that it actually takes you sending power back for that function...
