Features to know about

Brighter and More Reliable at Night: 10-Diode LED Backup Light

This 6-7/16" oval backup light uses 10 white LEDs behind a clear lens to throw a strong, even beam that helps when backing up or hooking up in the dark. It’s certified for use as a backup light in a 2-lamp system, meeting DOT, FMVSS 108, and CMVSS 108 standards so you know it’s road-legal and dependable. The LEDs last up to 50 times longer than incandescent bulbs, drawing just 0.26 amps at 12.8 volts for bright performance with very little power demand.

Built for the Wettest Conditions: Fully Submersible and Sealed

Water intrusion can ruin a light fast, but this one is built to handle it. The housing and clear lens are sonically sealed together into a single waterproof unit, so it’s safe for use on trailers that get dunked or splashed. No moisture gets in to corrode the diodes or short out the circuit board, making it ideal anywhere water is part of the job.

Simple, Secure Mounting: Recessed Fit with Standard Connections

The recessed design sits neatly in place using a grommet (sold separately) for a tight seal against the mounting surface. It accepts an industry-standard 2-prong plug (sold separately), making wiring quick and straightforward—no custom connectors or adapters needed.

Tough Against Wear and Tear: Durable Polycarbonate Construction

The light’s lens and housing are both made of polycarbonate for solid impact resistance and long life. There are no filaments to break or bulbs to replace—just clean, consistent light output every time you switch into reverse. A lifetime LED warranty backs that durability for peace of mind over years of use.

Excellent to deal with and fast shipping



by:

Product looks great, just wish I had known it needs a wire harness instead of just having the wires already installed.



by:

Finding and purchasing products from etrailer.com has always been easy. I have purchased many times from etrailer.com.
Parts arrive on time and never had a problem.
Good job.



by:

Delivery was quicker than expected. The answer to the review by the staff was extremely helpful in deciding which light would work for my intended use. Have bookmarked etrailer for all future purchasing.



by:

Was just what I was looking for. They had the red lights at our local store but I couldn't find the back-up lights so I went on line and found e-trailer. Realized I could have gotten everything from them and will keep them on my fav list.



by:

I made this purchase for my son's boat trailer. I ordered on the Monday before Thanksgiving and it arrived the day before. Everything arrived as expected and well packed. He can't wait to get this installed!

Thank you for the reply.You are correct the light has a three prong socket on the back but this light only uses one function. You need a ground connection and the reverse signal connection. The 2 prong plug I recommended will actually cover up that third slot so you dont have to worry about it getting dirty or damaged.



by:

Product worked fine. Only took a couple of minutes to replace my old trailer lights. Lights are much brighter than my old bulb type lights.



by:

Huge difference in brightness from these back up lights compared to those which came on my Ranch Hand Legend rear bumper. Product was as described and arrived sooner then I expected.



by:

etrailer.com had everything I needed to complete my trailer build, and at the right prices. The products are quality, with competitive pricing. etrailer.com delivered as promised, it was our local delivery that delayed sending the product out to my home, but one call to Pat, and the issue was immediately resolved, and I had the product that night! Great product, Great customer service!



by:

Etrailer.com is my "Go To" site for trailer lighting and parts. Always reasonable prices.



by:

These provide a lot more light than the bulb type lights. Connections on the back match what was on the trailer. I replaced the rubber grommets at the same time as they are not very expensive.



by:

Product well made and was as advertised. Led lights will be used in my Ranch Hand bumper.
Easy to install. I already have the mounting base and wiring.



by:

I ordered LED trailer running lights - were very easy to put in - not quite as bright as I would have liked, but did may a noticeable difference.



by:

Installed as an interior light in my horse trailer. Works great, although it was slightly bigger than the previous light and was a bit difficult to install. High output with very little power draw. Just plug in, no electrical work. Received very quickly.



by:

Very bright look great direct fit plug n play



by:

The lights are great, however, you should probably sell as a kit to include the mounting brackets and wiring harness. I had to make a second order to complete the installation on my truck.



by:

Adding backup lights to my boat trailer.



by:

I can't believe the difference in the looks of my Damon Outlaw Toy Hauler after adding the new LED taillights, not to mention how much safer it will be with the added visibility. The rear of the coach looks brand new with the old faded lights removed and replaced with your lights. Everything was just plug and play. Well worth the cost. Thanks, Michael

I get compliments on the way the motorhome looks all the time. The transformation was really worthwhile, and the back of the coach is MUCH MORE visible poor weather than it used to be. I am completely satisfied!



by:

Replaced your OEM lights with up to date clarity and the same fit with no hassle!



by:

Great and perfect replacement for the backup lights in my headache rack.



by:

the light fixture works very good except when used in the bracket, it leaves the back exposed to being hit by road debris. There is no cover on the light fixture. Therefore i went to a local fabricator and he made a fixture out of 2x4 steel tubing. The gasket fit perfectly but when i went to us the 2 wire pigtail, it was at the wrong angle for the light. I purchased another one locally. just wanted you to know that i could only use the light and the gasket.

Thank you for your prompt service.



by:

Product exactly as needed. Existing lamps last about 8 to 10 weeks as docking lights on my motorhome; there are four - one at each wheel. These lamps fit perfectly and are much brighter. My expectation is that these lamps will last more than a year(?) We'll see.

So far these lights have exceeded my every expectation! Absolutely no problems whatsoever. Thank you for making a quality product that I can depend on



by:

I purchased these Submersible LED bulbs for my boat trailer for two reasons. The first is so road traffic is aware of my intentions of backing up and the second is to make it easier to back my trailer into my driveway at night. The only thing that I find disappointing about this product, is that the wires are not sealed. You have to plug a pigtail in to power the bulb. Although they say it is watertight, I still plan on sealing the plug with some marine grade silicone sealant. Otherwise I am very satisfied with the way these bulbs light up my path of travel.



by:

Nice lights. I have the 36 diode oval LED lights mounted on a flatbed truck as reverse lights and they are not near as bright as these 10 diode lights. I have the 10 diode lights mounted inside a 6ftx20ft stock trailer on a toggle switch. There is one at the front and one at the back. They give off plenty of light to load and unload horses and cattle in the dark. I would buy these again for the next trailer I rebuild. The team at etrailer.com is top notch as well. Your order will ship the same day and arrive in a timely manner. If it does not they will tell you why. Great people to do business with.

  • 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...

  • Looking for Way to Mount Optronics Backup Light # BUL10CB on Ranger Trail Boat Trailer
    In order to mount the Optronics Backup Light, # BUL10CB, on your Ranger Trail Boat Trailer, I recommend using the Rubber Grommet, # a70gb, and Trailer Light Mounting Bracket, # BK70BB. A wiring harness, part # A49PB for a right angle plug and part # A45CB for a straight plug, will also be needed for the Optronics Backup Light, # BUL10CB. I have included a few short videos for you to check out.

  • Where to Gain Input For a Backup Light For a 2019 Chevrolet Equinox?
    You may be able to get a connection for a backup light in the rear fuse panel on your 2019 Chevy Equinox. I do see there is a circuit for the trailer reverse lights is F8 and K2 positions according to your owners manual. Do understand you may or may not have these circuits wired on your fuse panel and may need to get the signal from the wiring going into the tail light.

  • LED Reverse Light Recommendation for 2005 Toyota Prius
    Since you have a Prius I would strongly recommend going with an LED reverse light that will draw considerably less than the Halogen part # PL-807. For that you'd want the LED light part # BUL10CB with the bracket # BK70BB and the grommet # A70GB and you'd have a setup that draws only .28 of an amp per light. You'll also need a wiring pigtail like the part # A49PB. This could be ran to the reverse light circuit of your vehicle without overdrawing it.

  • How to Provide Power to Trailer Reverse Lights
    To connect back up lights you need to have a 7-way trailer connector on both your trailer and tow vehicle. On a 7-way the reverse lights are powered by the center pin. To connect reverse lights to the trailer's 7-way you can use 16 gauge wire # 16-1-1, or 14 gauge # DW07550-1 if you have a longer trailer. Both are sold by the foot. If you need reverse lights a couple of popular options are the Optronics LED Backup Light # BUL10CB for an LED that uses a 2-wire pigtail # A45CB to connect....

    You have a good plan! You are correct that once you have a functional 7-way connector and the Tekonsha Prodigy P3 # 90195 installed in your truck that you will not need any other wiring on the truck. Going with a junction box like the # 38656 to install the 7-way connector is the best way as it gives you a very nice location to make all of the wiring connections. All you will need to do is run the # 10-2-1 like you mentioned from the brake output post on the junction box to one wire...

  • Recommendation for Submersible LED Backup Lights on a Boat Trailer
    I can help you add reverse lights to your trailer. Yes, It is important to pay attention to DOT compliance when adding lights on your boat trailer. Compliance will be met if you use the Optronics # BUL10CB light as your backup light. The # BUL72CB is purposed for a utility light and will not meet the criteria for reverse lights on the roadway. In order to add reverse lights to your trailer would would need to have a 7-Way on the trailer and a 7-Way on the vehicle. On the vehicle side,...

  • Comparing Brightness Ratings of Optronics LED Tail Lights
    The Optronics LED Backup Light # BUL22CB is brighter than backup light # BUL10CB although I would not describe it as significant, though that can be subjective. Optronics measures the brightness of their lights using candelas and the # BUL10CB has a candela rating of 125, while the # BUL22CB has a candela rating of 160. There is also the backup light # BUL52CB which has a candela rating of 175. The reason I would not classify the brightness as significantly higher is because these lights...

  • Recommended Wiring And Waterproof Lights For 2000 Ranger 620 VDS Boat Trailer
    To completely rewire the trailer you will need to start with a 7-way trailer side wiring harness like part # H20044. You will then need a junction box like part # 38656 to attach to the trailer. You will run the # H20044 harness into the junction box and run the wiring for the brakes and lights off of the posts in the junction box. You will need the appropriate size wire for the lights and for brakes if you have them on the trailer. You will want to run 10 gauge wire like part # 10-1-1...

  • Do Trailer Reverse Lights Require Two or Three Wires to be Powered
    Reverse lights like the part # STL211RCB only need power and ground to function. You would not need three wires ran to the light assembly. Power would need to come from the reverse light circuit of the tow vehicle but you can ground the lights to the trailer frame or using wire to run back to ground of the trailer wiring. The version of the light I would recommend instead though is the part # BUL10CB since this is just a reverse light. For pigtail harnesses you'd want either the # A45CB...

  • How Much Amperage Is Required to Add Reverse Lights to Trailer
    If the tow vehicle has a trailer reverse light circuit separate for trailer wiring then you'd be limited by the amperage rating of the fuse that protects it. If you are tapping into the reverse light circuit of your vehicle for the light then it comes down to the amperage rating of the fuse that protects the circuit as well as the amperage rating of the lights and how many amps are left over between those two numbers.

  • Connecting New Reverse Lights Wiring At Trailer Electrical Connector For a Dump Trailer
    As long as your trailer has a 7-way you will more than likely have a Junction Box # 3375601101 that all the wiring from the 7-way will go into and connect to the trailer wiring. You will need to locate this box and find the wire for the reverse light circuit. This will typically be either the purple wire or yellow wire if your harness does not have a purple wire. A Test Light # PTW2993 can be used to verify that you are connecting to the correct wire. If your trailer uses a 6-way connector...

  • 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 Optronics Assembly for Adding Backup Lights to Sprinter

  • Reverse Light Wire Color on a 1996 Chevrolet K1500 Pickup to Allow Connection of Back Up Light
    The best way to confirm which wire activates your vehicle reverse lights is to remove one taillight assembly and visually identify which lead goes to the reverse light bulb. To remove the taillight, open the tailgate and locate and remove the two taillight retaining screws. This will allow you to pull out the taillight assembly for access to the wiring. Then, for safety sake, it will be useful to have a helper turn the ignition to the on position without starting the vehicle. Then place...

  • Difference in Brightness Between # BUL10CB Backup Light and # BUL72CB Utility Light
    Both the # BUL10CB and the # BUL72CB are 10 diode lamps, and therefore neither lamp would really be brighter than the other. The main difference between the two is how the light is focused. Because the # BUL10CB lamp is DOT compliant as a back-up light, the light would be more diffused over a wider area. By contrast, the # BUL72CB which is NOT certified as a back up light would have the light more focused on a smaller area. Each lamp would output a similar amount of light, but the # BUL72CB...

    I recommend using LED back up light # BUL10CB which is actually DOT approved as a backup light. With it I recommend grommet # a70gb, mounting bracket # BK70BB, and wiring harness # A49PB. On the wiring harness the white wire is the ground and will attach to a clean, bare metal surface. The red wire is for power and would need to be spliced into a reverse light wire behind a tail light on your 2015 Subaru Forester.

    Optronics light # BUL78CB is a utility light so it is not DOT approved to be used as anything other than that.

At a distance of 1 foot, the candela output is equal to the output in lumens. The next brightest 6-1/2 inch oval light would be the part # BUL22CB which has an output of 160 candela.
