Optronics BUL111CB Oval Sealed DOT LED Back Up Light Diagram

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.

PL-2 Wiring Connection

Optronics PL-3 Connection

This light has an industry-standard PL-3 connection as pictured above. The light accepts a 2-prong plug (A45CB or A49PB - both sold separately). The plug connects to 2 of the points on the PL-3 connection for power and ground. And the plug covers the unused third point on the connection to seal it against dirt and moisture.

Recessed-Mount Light

Recessed mount light

Recessed-mount trailer lights install underneath a housing or a grommet (A70GB) sold separately. These lights will extend into the mounting surface and require that a hole be cut into your trailer.

6-1/2" x 2-3/8" Oval. Waterproof trailer light is certified for backup light function in a 2-lamp system when a pair of lights is installed. Durable polycarbonate lens and housing. Recessed mount with grommet. Accepts 2-prong plug.


Incredibly bright, great addition to cargo trailer for seeing to reverse.


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.


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!!


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!


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


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.


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.


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.


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


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.


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!


Nice bright back up light, would recommend to anyone looking to replace there old style lights with led lights


As always the employees at etrailer answered all my questions and even offered a better solution to my issue that was less money. everything arrived on time and as promised. it is a pleasure doing business with them


After ups lost half my order the etrailer team corrected the mistake fast and fot me what i needed


Just wanted to say great service, excellent communication about my purchase, and better yet, lights are just what I expected m
Thanks Mark


Very bright. Love the amount of light it gives.


Super bright, not leaking after a year of use would buy again and again!


excellent light can see A good deal of the rear area. So I rate this a five. the shipping was spot on Too!


Everything fit perfectly! Customer service is top notch, delivered on time not one complaint here.

Worked great and very bright.




Very Good quality, Good price

  • 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!

  • 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.

  • Does GloLight LED Backup Light BUL111CB Come as Pair or One Light
    The GloLight LED Backup Light for Truck or Trailer - Submersible - 22 Diodes - Clear Lens # BUL111CB comes as a single light, so just one. For a pair you'd need to enter "2" in the "Quantity" box on the product page of the # BUL111CB.

  • 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.

  • Recommended Extremely Bright Trailer Reverse Light
    I'll do my best to be just as helpful as Rebecca. I do have a few options for you depending on the exact size you'll need. I know you said you aren't worried about being compliant with the DOT but the best options we have both are. The Optronics GloLight LED Backup Light # BUL111CB is a 6-1/2 inch by 2-3/8 inch light that will fit into an opening of 6-7/8 by 2-1/2 inches. It's a clear lens with 22 diodes. All of the different sizes and shapes of GloLights we have get very good reviews...

  • 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.

  • 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...

  • 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.

  • Recommended Oval Lights, Grommets, and Wiring for a BACKRACK Headache Rack for Pickup Truck
    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...

  • 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.

  • 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...

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.
