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.

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

Review from a similar Optronics 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

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

So far so good. Got the lights installed and tested them out and they look great! I will say packaging was questionable, they were loosely packed in a box that was too big with no bubble wrap or stuffing to keep them from bouncing around or against each other. Thankfully none appeared cracked or broken, and hopefully it's a sign of their toughness and not a sign of etrailer's lack of care. 383215

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

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. 190153

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. 586398

Review from a similar Optronics GloLight in Trailer Lights


Quite frankly, these are one of the nicest LED taillights I've seen. The glow of the tail-lamp is very modern and it's very bright. These replaced old halogen square tail-lights on a 2005 toyhauler, and it helped freshen up the look of the rear. I had to drill a few holes in the metal plate these attached to, as the three wires must have a direct exit so that they don't get pinched. Initially, these flashed an error code on my 2018 Superduty when I tested the turn-signals, but when I tested them again, the error code went away. Be aware that swapping out halogens for LED's on a trailer may make your tow vehicle throw a turn-signal error. 538942

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.. 484192


Comments

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.

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. 524591

I ordered both the ST9RB and ST8RB. After years of use, my other boat trailer lights were starting to cause me problems. I decided to order new ones for each side. These are a different make, but the connections were the same as were the mounting holes. Just took minutes to mount and both worked great. Nice bright lights again! Good price and fast shipping. I would definitely order again. 211119

Other than changing a bulb, they are still working like new! Money well spent.

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. 561727

Review from a similar Optronics GloLight in Trailer Lights


These lights are outstanding, they look amazing and have outstanding visibility in many light conditions, from the brightest of day to the darkest of night. The outer ring illumination for tail lights looks aggressive and adds style to an otherwise bland part of the trailer and because the light is so bright it commands attention. When braking or turning the center section steps the brightness up a notch to make sure people can tell without question what the driver’s intentions are. After getting a set of these for my trailer, there’s no question that I’m returning to Optronics for all my future lighting projects, from converting the tail lights on the semi tractor to this very set, to just replacement of burned out clearance lighting, Optronics has a customer for life in me 726681

Review from a similar Optronics GloLight in Trailer Lights


I would like to award more than 3 stars for this product but I have recently had issues with a few of these lights burning out. Normally, they are dependable so maybe I got a bad lot of lights during my last purchase. However, I DO like these glow lights as they are very bright and noticeable even in the daytime. That said, you would think that as LEDs go they would last a long time and I do have several in use that HAVE lasted, but I also have had several that burned out fairly quickly. I am happy to report that etrailer has stood behind the manufacturer Optronics lifetime warranty and replaced the defective lights. My advice for anyone considering using these lights is to employ them in an easy-to-access application so that if it becomes necessary to change out a defective light, you will not have difficulty in accessing the defective light(s). 714761

I would have given this purchase FIVE (5) stars but........... The assembly that I received had a sticker on the lens that I had to scrape off and use lighter fluid to get all of the residue off. Afterwards is showed signs of being scratched where the sticker was. Then I discovered that even though this was supposedly a “watertight” submersible tail light assy. There were no seals between the lenses and the assembly. So I thank God that I bought this assembly only for the 2 lenses and I had 2 old gaskets on the old assy. to keep the water out. I will say thank you very much for the quick shipment. And I will be buying more items from you in the future!!! 700086

Do you have a question about this Trailer Light?


  • 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...
