Optronics BUL12 Series Fleet Count 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-2 Connection

This light has an industry-standard PL-2 connection as pictured above. The light accepts a 2-prong plug (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.

Video Transcript for Optronics Trailer Lights - Tail Lights - BUL12CB Review

Today we're going to be taking a look at the LED back up light from Optronics. This is designed for trailers and utility trucks. This is certified for the back up light function and a 2 lamp system. When a pair of lights is installed, your second light is sold separately. The unit's going to be sonically sealed. It's got a water proof housing and lens unit so it can be submersed in water.

LEDs are going to make great replacements for incandescent lights. They're going to last much longer. They're going to be more efficient. They're going to burn brighter. You don't have to worry about replacing bulbs and you don't have to worry about burned out filaments.

The unit's going to feature a polycarbonite lens and housing. It's going to contain white LEDs with a nice clear lens. This is designed to be a recessed mount with a mounting grommet. Your grommet is sold separately. If you're in need of one, you can find them here at etrailer.com.

Here on the back side, we'll see that it will accept an industry standard 2 prong plug. Your plug is sold separately as well. If you're in need, you can find them here at etrailer.com. On the back you are going to notice a 3 pin connection. Now since this is a back up light, it just needs a ground and power connection. Optronics puts the 3 pin connector on most of their lights even though it may only require a 2 prong plug.

As you'll see later when we hook it up to power, a 2 prong plug will cover up all 3 connection points for a sealed design. The unit is Department of Transportation compliant. It meets FMVSS108 requirements. Taking a look at the dimensions, the overall length is going to give us a measurement of about 6 1/2". The overall height, that's going to measure about 2 1/4". The depth, measuring to the plug is going to measure about 1 3/4" and then just this portion here is going to measure 1" in depth. It's going to contain 6 LEDs or 6 diodes. The power draw is 0.260 amps at 12.8 volts and Optronics is going to put a lifetime warranty on the LEDs. We're going to go hook it up to our external power source. We'll also be able to turn off our overhead lights. Take our 2 prong plug, fit it into the ports here at the back. You can see that it creates a nice sealed design. You can see that the lights sends out a really nice consistent signal. Again, it's going to contain 6 LEDs, white LEDs with a clear lens and the multi diode design is really going to help optimize our light output. That's going to do it for today's look at the Optronics LED back up light for trucks or trailers.

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.

Ask the Experts about this Optronics Trailer Lights

  • How To Prevent Water From Getting Between Oval Trailer Light and Grommet
    The 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.

  • 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...

  • Reverse or Utility Lights to See When Backing Up Cargo Trailer
    If 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...

  • Is There a Class II Trailer Hitch Receiver Available for a 2008 Chrysler Sebring Convertible
    The 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.
