Features to know about
Better Backup Visibility: Bright 6-Diode LED Output
Backing up in the dark is no fun when your lights barely cut through the night. This Optronics LED backup light packs 6 bright white diodes behind a clear lens, certified for backup function in a 2-lamp system when a pair is installed. It’s more efficient than incandescent lights, drawing only 0.26 amps at 12.8 volts while delivering a clean, even beam that helps you see exactly what’s behind you. With LEDs rated to last about 50 times longer than standard bulbs, you get consistent performance with no fragile filaments or bulb changes to worry about.
Worry-Free in Wet Conditions: Fully Submersible and Sealed Design
Water and electricity don’t mix, but this light is built to take on wet environments without flinching. The housing and lens are sonically sealed into one waterproof unit, keeping moisture out so the diodes and circuit board stay protected. Whether it’s rain, road spray, or full submersion, this rugged light keeps working reliably without fogging or shorting out.
Built Tough for Everyday Use: Durable Polycarbonate Construction
Trailer lights take abuse from vibration and debris, so durability matters. Both the housing and lens are made from tough polycarbonate that resists cracks and chips. That means this oval light can handle rough roads and repeated use without losing clarity or performance. It’s also DOT compliant and meets FMVSS 108 requirements in any 360-degree position for dependable safety.
Clean Look and Easy Mounting: Recessed Fit with Standard Plug
A clean install makes all the difference. This 6-1/2" long by 2-1/4" tall light fits into a 6.85" x 2.5" cutout for a flush, recessed look when used with the compatible grommet (A70GB – sold separately). The industry-standard PL-2 connection accepts a simple PL-2 prong harness (sold separately) for power and ground, sealing off the unused third point against dirt and moisture. Once it’s snapped in place, the light sits secure and tidy—ready for years of service without loose fittings or messy wiring.

I called and spoke with Lisa D for a special order product that E-trailer needed to order directly from the manufacturer and have it added to their website, and Lisa D kept me updated every step of the way. She got the products order and shipped with a very quick turn around time, which was great b/c I couldn't find any company that could assist me with ordering the lights that i wanted. Very pleased with E-Trailer and Lisa D.

Ordered new LED clearance lights, taillights and clear interior lights to replace the non LED versions. They were shipped immediately with a confirmation. They were exactly as illustrated and what we needed for our horse trailer. Also came at a nice price!!
Would recommend shopping on their site

Added these lights to rear bumper (ranchhand) of my truck. Perfect fit and throw a lot of light. I use them in no and low light situations for hooking up the tow bar for towing my Jeep and for backing up.

These lights are awesome. We originally installed them on one of our heavy duty utility trailers and now we are adding them to our flatbed utility truck as well. Nice and bright, sleek design, easy wiring, and great flush mount fit all add up to a really terriffic product!!

Yes, I ordered six BUL12CB led lights, but I received six MCL 131RC210B side marker lights which I did not order. I just send an email to etrailer to find out what can be done about this. I don't want to have to pay a return fee and I wanted these lights by 9-14-2022 for an upcoming horse show.

Really like how much these light up the tack room. Much brighter than the incandescent lights (which burnt out because they overheated). Plus, they use less power from my horse trailer battery. Now, I plan to replace the incandescent lights in the horse end of the trailer.

See what our Experts say about this Optronics Trailer Lights
- Is the Optronics LED Backup Light BUL12CB Only Able to Be Used as a Reverse Light? Hey Brady, welcome back! The Optronics LED Backup Light item # BUL12CB is designed to just be a backup light but you can wire it to any circuit you want. If you wire it to a reverse circuit it will only get power when your tow vehicle's in reverse. If you wire it to a running light circuit it'll be on the entire time your lights are. Please note that it is illegal almost everywhere to have rear-facing white lights on while driving forward on public roads. I found this out the hard way...
view full answer... - What is the Candela Output of Optronics 6-1/2 Inch Incandescent and LED Tail Lights?I do recommend you move to LED lights as they are going to last much longer than the incandescent lights on your horse trailer. As far as light output, Optronics generally measures their lights in candelas instead of lumens though at a distance of 1 foot candela is equal to lumens so you should have a good idea of how bright the lights are. I contacted Optronics and the representative was able to give me the candelas of each of the lights you were asking about. The incandescent # BU70CB...
view full answer... - Recommended Replacement Back Up Lights For a 2003 Ranger Trail Boat TrailerFor your 2003 Ranger Trail Boat Trailer I recommend upgrading to the larger Optronics LED Backup Light # BUL12CB. These lights are submersible and have a clear lens with 6 bright LED's to improve visibility when backing up over your stock lights. These lights will require a cutout 6.85" long by 2.5" tall. A Grommet # a70gb is used to hold the light in place and they are wired with a Pigtail # A86PB. This will make it easier to replace lights in the future if they become damage.
view full answer... - How To Prevent Water From Getting Between Oval Trailer Light and GrommetThe Optronics LED Backup Light for Truck or Trailer part # BUL12CB is submersible yes but the fit inside the PVC Grommet part # a70gb is not water tight. Therefore, water could indeed get between the light and grommet but the grommet is not really designed to keep water out but rather just to hold the light in place. However, if you were to add gasket maker like part # LT37467 around the light and inside the grommet that would then give you your best chance of keeping water out.
view full answer... - Reverse or Utility Lights to See When Backing Up Cargo TrailerIf your trailer has a 7-Way connector and the vehicle side has the center pin active when the vehicle is in reverse then you can install backup lights on the trailer and wire them to the center pin. You can use 2 of backup light # BUL12CB 2 of grommet # a70gb 2 of bracket # BK70BB And 2 of pigtail # A49PB If you do not have a 7-Way but just a 4-Way instead you could wire a utility light such as # TLL48FB in with the running light wire on the trailer and have the utility light run on a...
view full answer... - Oval LED Reverse Lights with Grommet for Flatbed TrailerWe have exactly what you are looking for in terms of an LED reverse light that fits with a grommet for your flatbed trailer. The Optronics LED Backup Light for Truck or Trailer - 6 Diodes # BUL12CB or the same light with 10 Diodes # BUL10CB can be mounted to your trailer with PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB and you will just need a 2-wire pigtail for the lights. For this you can use 2-Wire Pigtail # A45CB or Right Angle 2-Wire Pigtail # A49PB. I have added links...

- Is There a Class II Trailer Hitch Receiver Available for a 2008 Chrysler Sebring ConvertibleThe only trailer hitch receiver option for your 2008 Chrysler Sebring Convertible is the Draw-Tite Sportframe # 24871, which is only a Class I hitch. Due to the design of your Sebring, there are no Class II options available. This trailer hitch has a Gross Trailer Weight (GTW) of 2,000 lbs and a Tongue Weight (TW) of 200 lbs. I checked an online version of a manual for you Sebring and if had the same weight capacities that this hitch has, but you will want to check your copy of the owner's...
view full answer... - Recommended Clear/Frosted LED Replacement Backup Light Equivalent to Optronics ST70RBFor backup lights for your horse trailer I recommend the # BUL12CB Optronics LED Backup Light for Truck or Trailer - Submersible - 6 Diodes - Oval - Clear Lens. This has the same dimensions as the # ST70RB at 6-1/2" long and 2-1/4" tall. The depth is less at 1-3/4" since it is an LED and not incandescent. If you want to replace the grommet when you replace the lights, I recommend the #a70gb PVC Grommet for 6-1/2" Oval Trailer Tail Lights. I have attached a video review for your reference.
