Features to know about

Bright, Efficient Backup Lighting: ONE Series LED Output

This 6-1/2" oval Optronics ONE Series backup light puts out a strong white beam while using just 0.26 amps at 12.8 volts. With a single LED diode, it’s designed to deliver the brightness of multi-diode lights but with less power draw and heat. The solid-state LED design lasts up to 50 times longer than an incandescent bulb, so you can forget about changing burned-out filaments or dealing with dim backup lights again.

Built to Take on Water: Sonically Sealed and Submersible

If your trailer sees frequent dunking or wet roads, this light is made for it. The housing and lens are sonically sealed into one waterproof unit that keeps out moisture—even during submersion. That sealed construction protects the internal diode and circuit board from corrosion or shorting, keeping the light clear and reliable in harsh conditions.

Tough Construction for Rough Roads: Durable SMT Design

Road shocks and vibration are no problem here. The surface-mount technology (SMT) used in the circuit board gives this light better heat distribution and stronger impact resistance compared to older designs. The polycarbonate lens and housing add even more durability, making it ready for off-road trailers, utility haulers, and heavy use without flickering or failure.

Clean, Simple Installation: Recessed Mount with PL-2 Connection

This recessed-mount light fits into a grommet (A70GB sold separately) for a clean look that sits flush with the surface. The PL-2 connector accepts a standard 2-prong plug (A45CB or A49PB sold separately) for power and ground, while sealing off the unused terminal from dirt and moisture. Once it’s in place, there’s no extra wiring fuss—just plug in and go.

DOT-Compliant and Ready to Work: Certified for Backup Use

When installed as a pair, this model is certified for backup light function in a 2-lamp system. It meets FMVSS 108 and CMVSS 108 standards, so it’s legal and safe for road use anywhere those regulations apply. Reliable lighting that checks every box—bright, efficient, sealed, and compliant.

Perfect replacement for Skeeter trailer

Great customer service



by:

I will use these on my boat trailer. They are just what I was looking for.



by:

Simple, reliable, does what it should. A good value.



by:

Perfect fit. Just what we needed to replace one in our horse trailer! thank you



by:

Exact replacement. Nice white light upgrade over the dirty incandescent light. Crazy fast shipping.



by:

I looked through 10+ stores online and etrailer was the only place that carries what product I needed and they were fast on shipping it out so thanks guys



by:

Works great. Brighter than the original backup lights on my boat trailer.



by:

Perfect fit, well made, bright!



by:

Fit perfect, works great, prompt shipping, no problems. Thanks for having what I needed. Back up light for boat trailer helps a lot when launching your boat in the dark.



by:

I was disappointed in the posting of the progress of my order and the lack of time it took to start processing it but in the end, I did receive in on the day I expected it and
the product was exactly as it was presented in the online description. I used it for incandescent lights in my daughter's horse trailer and they were an exact fit for the mountings in the trailer. My daughter and grandson said "WOW, that is bright" which is what they wanted. Thanks



by:

Found the products I needed to replace my horse trailer's back-up & tail lights. Placed the order easily and received them quickly. Was able to remove the old ones and install the new ones in minutes and now we have turn signals, brakes, tail & back-up lights again -- all working! Will definitely use this site again should we need any other parts.



by:

It was just what I needed fit prefect and works great



by:

I purchased a pair a pair of white grommet mounted LED lights that I installed in my blasting cabinet. The are bright and add the necessary additional light. They are powered by an, old but good, 12V battery that is hooked to a battery maintainer.



by:

I replaced my internal horse trailer lights with these LED’s. They are brighter than the original lights and of course, use less battery.

Perfect performance so far. We are getting ready to upgrade our other horse trailer lights with these same lights.



by:

Nice bright light. Used to backlight the skeeter cutout on my boat trailer.



by:

Not the brightest light, but definitely bright enough for reverse/backup applications. I wish someone made a curved light/lems like this with multiple LEDs, but the only ones I’ve found are the flat lens oval lights, like those seen on industrial vehicles. This is still much better than the old style incandescent lighting that originally came on my trailer.



by:

Perfect fit, easy installation. Used inside the horse area of a living quarters horse trailer.

See what our Experts say about this Optronics Trailer Lights

  • 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...

  • Oval LED Trailer Taillights that are Red and White with More than One Diode
    Hey Brian, for white you could use the part # BUL72CB which has 10 diodes and then for red # STL72RB which is also 10 diodes.

  • Replacement Clear Light for Peterson PM 421
    We do have a wide selection of oval tail lights with similar dimensions but none that match yours exactly. I am also not sure if the clear light you are referring to is a backup light with white bulbs or a tail light with red bulbs. If you can send me a photo of your Peterson PM 421 tail light and confirm its function then I may have a better option for you but according to my research, the ONE LED Trailer Tail Light part # STL002RMB with the PVC Grommet part # A70GB is a direct replacement....

  • Tips for Installing 6-1/2 Inch Oval Trailer Lights and Grommet in Trailer Frame
    PVC Grommet # a70gb and the lights that fit with them have to have a tight fit in the trailer. Try to press them into the hole as evenly on both sides as possible. Using some soapy water on the grommet and trailer will help it to install easier. If your trailer takes the same size backup lights you can use # BUL002CB with wiring # A45CB which also fits that same grommet.

  • How to Upgrade 4-Pole Wiring to Allow Use of Trailer Reverse Lights
    If the reverse light you are adding to your boat trailer is a single-function light like # BUL002CB (not a combination tail and reverse light like # STL68RB) and it has two wires, red and black, it should not matter which one you connect to ground. This is easy enough to check just by briefly connecting the light wires to your vehicle's battery; try it both ways (red to battery positive and red to battery negative) and see if it functions the same way with both wiring options. If it is...

  • Backup Camera with No-Splice Installation in 2014 Ram 1500
    A backup camera system like the Hopkins Smart Hitch # HM50002 does use a T-connector at your truck's existing 7-way trailer socket to connect to its 12V, ground and reverse circuit wiring that operate the camera. When you shift the vehicle into reverse that lighting circuit activates the camera and monitor automatically. If you needed to access the +12V circuit in order to wire in an additional backup light such as # BUL002CB, you could simply tap into the +12V wire on the T-connector...

  • 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.

  • Number of Prongs on Optronics ONE LED Backup Light
    The Optronics ONE LED Backup Light # BUL002CB does have three prongs on the back however only two are used. The 2-wire pigtail to use with the light is # A45CB or if you want a right angle plug use # A49PB. To install the light the PVC grommet is # A70GB.

  • How to Wire White LED Lights with 3 Wires to a 1997 Honda Goldwing
    How you wire up lights such as # BUL002CB or a similar light is going to depend on what function you need the lights to perform. You also have to check the state DOT regulations for motorcycles to determine if you can have white lights on the front of your bike that are not head lights. If you want to be able to turn the lights on and off as needed then you would just need to attach the white ground wire to a bare metal surface. The red wire you could run to a switch such as # PK34513...
