Features to know about

Brighter and More Efficient Lighting: 22-Diode GloLight Design

When you need serious illumination behind you, this light makes a big difference. The GloLight LED Backup Light uses 22 white diodes that deliver a bright, even beam while drawing only 0.386 amps at 12.8 volts. The smooth outer ring design gives a clean, modern look and provides a bright glow that’s easy to see day or night. LEDs last up to 50 times longer than incandescent bulbs, so you won’t be chasing replacements or dealing with burnt filaments again.

Built for Wet Conditions: Fully Submersible, Sonically Sealed Housing

If your trailer ever hits the ramp or sees wet roads, this light is made to handle it. The lens and housing are sonically sealed into one waterproof unit that keeps moisture and debris out completely. That means no fogging, no corrosion on the diodes, and no electrical issues after submersion. It’s a dependable choice for anyone who needs a true submersible backup light.

Clean Installations That Fit Exactly Right: Recessed Mount with Grommet

This oval light measures 6-1/2" long x 2-3/8" tall x 1-3/4" deep and fits perfectly into a 6-7/8" x 2-1/2" hole for a clean recessed mount. It works with the A70GB grommet (sold separately) so the fit stays snug and protected. The compact design keeps the light tucked in close so it’s out of the way but still easy to see from behind.

Reliable Connections Every Time: Standard PL-3 Plug Compatibility

No custom wiring needed here. This light accepts the industry-standard 2-prong PL-3 plug—either A45CB for straight wiring or A49PB for right-angle setups (both sold separately). That connection style seals tight against dirt and moisture, keeping your wiring protected while giving consistent power and ground contact wherever you use it.

DOT Compliant and Built to Last: Certified Performance You Can Trust

The GloLight LED Backup Light meets FMVSS 108 requirements in any 360-degree position, so it’s ready for use anywhere DOT compliance is needed. With its durable polycarbonate lens and housing plus a lifetime warranty on the LEDs, this is a solid long-term lighting upgrade that performs every time you put it to work.

Hey Daniel W,
Got my lites today, Friday.
Am very happy with them. Actually they are much better and brighter than the originals and less expensive. Thanks for your help. You've got a customer for life. Oh and by the way, it's nice to be able to actually talk to a person.

Thanks again!

by:

Great Quality and great service. The LEDs are bright and just simply cool looking. They get everyone's attention during the day and really wicked looking at night! I highly recommend etrailer I use them again and again!!



by:

White reverse light for boat trailer. Easy replacement by just unplugging old light and plugging 3 prong wire plug into this light. Very bright.



by:

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.



by:

Excellent quality
Only etrailer provides
you a video demonstration of the product you are purchasing. It's better than walking into an actual store in my opinion. Every detail from instructions to installation pictures is available on site.



by:

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



by:

I installed 2 of these on the back of a 28' gooseneck. They really help when backing at night, not to mention letting other drivers know that you intend to back up.
If I don't keep forgetting, I will get pictures of the lights in the dark.



by:

My backup lights on my 15' box truck had gotten very yellowed and hazed. With these I can easily see behind me when backing up my driveway. The original backup lights were not this bright.



by:

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!



by:

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.

  • Rewiring Boat Trailer for 7-Way to Use LED Lights
    There are a number of things you will need if you want to re-wire your boat trailer to use LED lights and you should start with Junction Box # 3375601100 and 7-Way # HM20041. Keep in mind you will also need Ring Terminals # 44-5310A and Loom Clamps # A0500 For LED lights I highly recommend checking out the LED Trailer Tail Light # STL57RB (Driver's side) and # STL56RB (Passenger's side). These are submersible lights with a total of 40 diodes and have mounting holes that are 2" center to...

  • Recommended 6 Inch Oval LED Backup Light For Brightness
    We have 6-1/2 inch oval LED lights that are very bright, that are typically referred to as 6 inch lights in the trailer industry. I recommend the Optronics GloLight LED Backup Light for Truck or Trailer - Submersible - 22 Diodes, # BUL111CB, because it is a very bright replacement light that that meets the DOT compliant standards. They have a very clean look and are sonically sealed so they can handle all the weather thrown at them. They require a recessed mount # a70gb, and a 2-prong...

    Using the Mighty Cord Wishbone 4-Way Flat Trailer Connector - Trailer End - 25' # A10-4225VP will give you the wiring for the tail lights on each side of your trailer giving you both the running light for each side and then the stop/turn function for each side.

    I'd be more than happy to help! Here is what I found: Red - # STL111RB (x2) Amber - # STL111AB (x2) White - # BUL111CB (x2) PVC Grommet - # a70gb (x6) Pigtail - # A47PB or # A45PB (x6) These lights all match and measure 6-7/16" wide x 2-5/16" tall x 15/16" deep but the grommet will take up the rest of the space that you measured. Just be sure to only connect 1 of the wires for each function depending on how you're wanting it all to operate. I have attached a sample installation video...

  • Trailer Reverse Lights That Do Not Require A Hole For Recessed Mounting
    For white led backup lights with a bracket, you can use the Trailer Light Mounting Bracket # BK70BB with a PVC Grommet # a70gb and the 6-1/2" backup light of your choosing. I recommend the Light Guide LED Truck/Trailer Light # BUL602CRB. These lights both act as a backup light as well as a provide an additional tail light to ensure that the you are clearly seen. You will need a 3-Wire Pigtail # A45PB to connect the light to the wiring on your trailer. We also have either the Hot-Line...

  • Installing Submersible Back-up Lights On A Boat Trailer
    To add additional backup lights like GloLight LED Backup Light for Truck or Trailer - Submersible - 22 Diodes - Oval - Clear Lens - Qty 1 # BUL111CB, you will want to splice into the reverse function wire on your trailer. For a 7-way, this is typically the purple wire, and for a 5 way, it is typically a blue wire. I've attached an article to assist. You will want to check for function before splicing as you can't always trust color. You can use a circuit tester like # PTW2993 for function. I...

  • What are the Brightest 6.5" Oval Lights for my Motorhome
    Because the GloLight LED Backup Light for Truck or Trailer part # BUL111CB slightly diffuses the light around the outside of the light I recommend using the LED Backup Light for Truck or Trailer part # BUL10CB. This will give you a slightly brighter light than the other. To be honest the difference is minimal and I like the looks of the GloLight better but for maximin brightness the second option is the better of the two.

  • Do the Diodes and Ring Light Up Separately on the Optronics GloLight LED Backup Light
    The diodes are actually the only things that light up on the GloLight LED Backup Light # BUL111CB. So when they light up the ring technically lights up (see attached photo). We do have the surface mount version as part # BUL111CFPG!

    The GloLight LED Backup Light for Truck or Trailer # BUL111CB that you mentioned is going to be your best option if you are looking for the brightest backup lights in the oval recessed mount style.

  • Availability of Replacement 6 x 2-1/2 Curved Grommet Mount Taillight to Fit Rear Corner of Trailer
    Although all the oval-style 6 x 2-1/2 grommet mounted reverse lamps we offer are meant to be mounted on a flat surface, we might have a solution that'll work for you. If the lamp isn't sealed and uses a typical replaceable 1156 single function bulb you can replace the bulb with an LED assembly like part # ARC28FR. The bulbs are similar in size to an 1156 bulb, so they'll fit just fine in the existing lamp housing. If your back up lamps use a different bulb, let me know which bulb they...

  • LED Tail Light for Boat Trailer
    There are no white, oval LED tail lights we carry which have a curved face. We do carry the 22 diode GloLight LED Backup Light # BUL111CB which is submersible but you would need to make your own mounting spot as it is a recess mount that also requires Grommet # A70GB and 2-prong plug such as # A49PB.

  • How to Install BUL111CB to Get Just the Outer Ring to Light
    You can use this light # BUL111CB just as you are wanting to. You will just need to connect to the ground and the taillight function. This will just allow the ring to light up. The other connection will be the brake/turn connection which will light up the inside lights and the ring.

    If you are looking for an oval shape, we have the GloLight LED Backup Light for Truck or Trailer - Submersible - 22 Diodes - Oval - Clear Lens - Qty 1 # BUL111CB which is rubber mounted using # A70GB. This light requires pigtail # A45CB or 90 degree # A49PB. If you are looking for a round light, I recommend the 2 inch # UCL50CB. This will use the same pigtail, but will use grommet # A54GB.

  • What Gauge Is The Wiring For The Pigtails That Connect To GloLight LED Backup Light # BUL111CB?
    The Pigtails # A45CB and # A49PB for the GloLight LED Backup Light # BUL111CB both use 18 gauge wiring. The Deka Heat Shrink Butt Connectors # DW05743-5 will allow you to make your wiring connections water tight. For the plugs you will need to use Dielectric Grease # 11755 to keep moisture out of the connectors and prevent wiring shorts.

  • Submersible Back Up Lamp For Launching Boat After Dark
    According to Buyers Products, their # 3371492135 Low Profile LED floodlight is not submersible. If the lamp was submerged it would be damaged. We do however have an alternative. I'd recommend using part # BUL111CB, along with the # A70GB grommet and the # BK70BB bracket. You could mount this setup under the bumper of your Sequoia and since the lamp is fully submersible, you wouldn't need to worry about it being damaged should it go underwater.

  • Trouble Seeing Out of VueSMART RV and Trailer Backup Camera at Night
    The LED lights on the VueSMART RV and Trailer Backup Camera # HM34FR are a common complaint among users. This is due to the very limited amount of light the LED's give off. If the lights were brighter it would cause the image to be difficult to see that close to the camera. Do be sure to check the brightness on your phone or tablet as they will often go dark at night making it even more difficult to see anything in the camera.
