Still completely satisfied highly recommend this product

Lights are bright and extremely visible to following vehicles - they made my friend with a similar trailer with old style incandescent lights jealous. Etrailer was completely supportive solving a minor technical installation issue.

A year along and they work great. Never concerned about my visibility to those following.

I installed them on the upper rear of my Casita trailer for better visibility as the OEM lights were to low.

Great! now people can see what Im going to do, turn or stop



by:

Replaced the cracked and foggy 30 year old lights on my popup trailer with a pair of these. They were exactly as advertised and look really great compared to the old original lights. Plus they are much brighter/easier to see... and the blinking action is much sharper... these are definitely much safer the the original lights.
The glo light effect is pretty cool and breathes new life into my old popup camper!
The lights are still working fine after a year.



by:

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.



by:

The Glolight LED trailer set is the perfect replacement for my tow dolly. It is light weight and much more visible than the standard bulb lamp set the trailer was equipped with. Installation was quick and very easy, I will recommend this to all needing to change theirs out...



by:

Installed on the rear of my tow vehicle for a permanent fix to the magnetic mounted lights I was using. These lights are amazing. The running light element is very noticeable and the turn signals can be seen from a great distance. Easy to install, easy to wire and look great!



by:

I love the look of these led lights at night.

a lot of positive comments also. Shipping time was awesome. Thanks George and Carol.

by:

Used the lights on my Harley servi-car, they look pretty good for trailer lights. The LEDs draw a lot less wattage than the lights that were on there. My charging system thanks you.



by:

Happy with the purchase etrailer got my parts in quickly. Wasn't really sure if these were the lights I wanted but thanks to the videos etrailer provides makes it easier to choose the right lights.



by:

These lights were quick and easy to install thanks to surface mount. Wiring was simple, took extra time to solder connections. These look great and are bright. Replaced old incandescent fixtures on a 20 year old pop up trailer.



by:

GloLight is great quality. We're using these to replace the tail lights on our ambulance RV conversion. Our first set were flush mount and we're very pleased with them, so we ordered this set which are not flush mount so we can mount them as needed. We've also ordered GloSteps from etrailer and are extremely pleased with those as well. Shipping is always so fast! We will remain a returning customer.



by:

Light installation was very easy, provides a good " BRIGHT LIGHT " over the stock light that came with the trailer.



by:

I had to replace the tail lights on my 2009 Skeeter trailer. The trailer is an EZLoader trailer and these lights attached exactly as the original ones did. And actually look better than original ones.



by:

Good quality and very bright.



by:

I ordered new taillights for a trailer I purchased they arrived in a timely manner and in good condition, I have not had a chance to install them yet,were less expensive than I could get locally



by:

Great service, product arrived as promi sed.



by:

This trailer light was exactly what I needed to replace one that was leaking water. It was an easy install and works perfectly.



by:

Have not installed this light yet, but the low profile and compact design will work well with my new flatbed trailer.



by:

Nice bright and sleek looking. No problems so far, all LEDs still work after a year. The trailer has been sitting out in the environment the whole time.



by:

Great addition to my motorcycle. Attached them to my saddlebags and they light up half of the street block at night! Very bright. Nice addition to be seen at night.



by:

great customer service and warranty replacement, highly recommend product and company, thx



by:

The product is excellent, I was amazed how much better than my old lights these units were. The way the break light shows from the running light is very clear and would make breaking and turn signals a lot clearer to other drivers.



by:

great service

  • How to Wire the GloLight LED Trailer Tail Light Part # STL178RB to a Trailer Connector
    The white wire on the back of the GloLight LED Trailer Tail Light part # STL178RB is for the ground. If you were wiring it to a trailer connector like part # HMC20031 then you would just need to make sure that it is attached to the ground terminal and no additional grounds would be needed. The outer ring of the light that you are referring to is made of plastic just like the body of the light is. The wire leads are around 6" long. I have attached a review video for you.

  • Best Thin, Surface-Mounted Trailer Tail Lights
    The best surface-mounted, thin trailer tail light is an LED light from Optronics: - GloLight LED Trailer Tail Light # STL178RB This is the best light for a number of reasons, starting with its 22 diodes, which will give it a brighter, more visible look than similar lights. It also has an LED circuit board designed specifically to resist shock which allows it to hold up over time, and it is completely waterproof which means no matter the weather - or even if you submerge it if you have...

  • What Are the DOT Requirements for License Plate Lights
    You'll only need a license plate light like the # OPT77FR directly over the license plate, on whatever side of the trailer that you're mounting the plate. What the 2 on each side is referring to is that you could use 2 lights on each side of the license plate if you wanted, or 1 directly over the center of the plate, but I can understand why the wording here is confusing. You can easily mount this under the # STL178RB you've already installed and make the trailer DOT compliant. I've linked...

  • How To Re-Wire Your Boat Trailer's 5 Way Wiring And Install New LED Lights
    I recommend using 40 Ft 5-Way Trailer Wiring Harness # A40W5B, which is a kit that will replace your entire 5 way boat wiring setup and give you the 5 way connection at the front of the trailer. The lighting wires are 40 feet long, which will be more than enough. It comes with a 30" ground wire (white) that will be connected to the frame of your trailer. The blue wire is 60" and will be connected to your brake solenoid if you have one; your trailer may not require this, as it may use a...

  • Does Optronics LED Trailer Light Use Reflector Ring
    The GloLight LED Trailer Tail Light # STL178RB will not work with the Snap-on Reflector Ring for STL78RB Series LED Lights # A78RXB as it will not fit the light. If you wanted to use that reflector ring you would need the Optronics LED Trailer Tail Light # STL78RB. This is similar to the GloLight but has a lip around the edge that allows it to accept the Reflector Ring. You can use these lights for your trailer as long as they have the side marker lights.

  • Wire Color Functions of the GloLight LED Trailer Tail Light # STL178RB

  • Replacement LED Light Recommendations For Trailer
    For a grommet mount red 2 inch clearance light I recommend part # MCL55R1224B. This light uses a 2-wire pigtail, part # A46PB for installation. If you need amber, you would order part # MCL55A1224B. Installed without a grommet, these lights measure 2 inches diameter x 1 inch deep. You can use the 2 inch grommet part # A54GB for this light for a flush mount. It would require a 2-5/16 inch mounting hole. The tail lights I recommend are the Optronics GLOLight LED Stop/Turn/Tail Light, part...

  • Cargo Trailer Lighting That Splices Into Existing Wiring
    If your current lights with a rubber flange are ineffective, the GloLight LED Trailer Tail Light - Stop, Tail, Turn # STL178RB would be a good option as a replacement as long as the dimensions of 7-1/2" wide x 3-5/16" tall x 1-1/8" work for your trailer. The GloLight has a built-in polycarbonate flange which should offer you more stability.

  • Optronics 6-1/2 by 2-1/4 Inch Oval LED GloLight, Mounting Bracket, Grommet, and Pigtail
    For Trailer Light Mounting Bracket # BK70BB you would use light # STL111RB with grommet # a70gb and wiring pigtail # A47PB. I have included links to videos of all three of these parts for you. Light # STL178RB would not fit in the mounting bracket since it has its own flange for surface mounting.

  • Brake Lights and Fender Lights for Enclosed Trailer
    We can get you the right lights for your trailer, but just keep in mind that we don't have a way of knowing the exact replacement lights on any trailer, so if you want to utilize the same mounting holes, for example, you will need to measure the center-to-center mounting dimensions, or you can simply make new mounting holes if you like. From what I can see of photos I looked up of your trailer, they all seem to be surface-mounted lights, so here is a list of what you can use. - GloLight...

  • Trailer Wiring Harness for 2008 Toyota Prius that Can Be Used with LED Taillights
    We have trailer wiring harnesses that fit your 2008 Toyota Prius and are compatible with LED trailer lights like the # 118505. We don't have taillights for trailers that match exactly what you are looking for but we do have the part # STL178RB which is oval shaped and has a ring around the perimeter for it that offers the stop and turn signal function.

  • Compatibility of Optronics Glo Light LED and Chrome Accent Trim Ring
    I reached out to my contact at Optronics and was able to confirm that the GloLight LED Trailer Tail Light - Stop, Tail, Turn - Submersible - Oval - Red Lens - Hardwire # STL178RB is compatible with Chrome Accent Ring for STL78 and BUL78 LED Series Trailer Lights # A78CB. They will fit together perfectly.

  • Which Diodes of the Optronics Light Illuminate When Brakes/Running Lights Apply STL78RB
    When the running light circuit is activated all diodes of the # STL78RB would activate. When the brake lights or blinkers are applied the outside diodes get brighter. To see the difference check out the review video I attached. The GloLight part # STL178RB is also a great choice. I attached a review video for this light as well for you to see the differences.

  • Can Optronics Trailer Taillight # STL178RB be Used as Just Stop and Taillight
    The part # STL178RB you have now can also be used as just a stop and running light assembly. All that matters is the way it's wired since you are wanting to use it only as a stop and tail. So for that you'd need the # 118158 to separate out the stop from turn circuit so that you could have the lights ran as only the two circuits you want.

  • How Long Will Optronics GLOLight LED Stop/Turn/Tail Light # STL178RB Run w/ 7 Amp-Hour Battery
    The Optronics GLOLight LED Stop/Turn/Tail Light, # STL178RB, draws a total of .885 amps, .59 amps for the stop/turn lights and .295 for the taillight. Since you are planning to use a 7 amp-hour sealed lead acid battery to continuously power the light, I am going to estimate that the battery will last approximately 7 to 8 hours. Please keep in mind that the condition of the battery is going to greatly affect the run time of the lights.
