Optronics BUL002 Series LED Oval 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-2 Connection

This light has an industry-standard PL-2 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-2 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.

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

- BUL002CB

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.

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

- BUL002CB

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.

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

- BUL002CB

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.

- BUL002CB

Review from a similar ONE in Trailer Lights

LED light was a perfect fit and easy install. In attached photo LED is on right and incandescent on left in photo (daylight photo was darkened to show lights better). The photo doesn't show it clearly, but both my wife and I believe it is slightly brighter than the incandescent bulb. I have had some trouble in the past with the incandescent bulb not making contact. This should not be a problem with the LED bulb.

My Son picked up the trailer today to use and the tail lights were working fine. Very bright.

Review from a similar ONE in Trailer Lights

I just got a new tracker boat & trailer and I did not notice the taillight light was cracked (it still worked). This light cost more then most, but the quality is evident immediately and a perfect match from the old one. It was a 5 min. replacement.

Review from a similar ONE in Trailer Lights

So i have a 94 Jayco pop up that one of the tail lights got smashed. The company that made those lights is no longer around. After some searching on etrailer.com I decided on these LED lights. Price was right. My only real complaint is that these lights come with nothing. No screws, no instructions, no seals. So when I pulled my old lights and found that they had 4 wires and these lights had 3, time to do some research. None of the wire colors matched up. Not the trailer wires, not the old lights etc. On etrailer there is a video describing the lights in detail. Watch it. He goes over what color wire does what on the new light. I hooked the trailer up to the car to figure out the old lights wiring scheme. I was able to figure it out from there, though you cannot wire both sides up the same, if you do when you put the turn singles on they both flash. I had to leave the brake light wire disconnected on one side. Brake lights still work without it. I used plumbers putty to create a seal. That is also what they used on the originals and I used the original screws to make new holes and mount the lights. All in all it worked out but instructions would have been greatly appreciated!. I am sure etrailer would have jumped in to assist if I asked but it was not needed. Pictures posted. Old lights on bumper for reference.

Review from a similar ONE in Trailer Lights

Product and service brilliant. One the big things in service have been sorted, eg. good product, value for money (not cheapest) delivered in good condition in a predicted timeframe, it's the little things like an email with tracking url that has ALL the information you need... WITHOUT HAVE TO TYPE IN A TRACKING NUMBER , NAME, ZIP ETC. And same with review, click on a url in an email and enter your comments with pictures .....SIMPLE. so many other companies just make these types of things too complicated and onerous for the customer to provide feedback. Also each person in the process is named! Brilliant, personal and just nice. I wish you guys were responsible for all of my transactions for all the things I buy online. Thank you to all of you at etrailer fantastic job.

Ask the Experts about this Optronics Trailer Lights

  • 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...

  • 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.

  • 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 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...

  • 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...

  • 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.

  • 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....

  • 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...
