Features to know about

Bright and Reliable Backup Visibility: Clear Lens with 1.6 Amp Draw

When you need a dependable backup light that lights the way clearly, this rectangular unit delivers. At 12.8 volts, it draws only 1.6 amps while producing bright, even illumination through its clear lens. The polycarbonate housing and lens keep things durable, so you get consistent performance every time you use it.

No Need for Separate Reflectors: Built-In Red Reflex Design

Keeping your trailer or utility setup compliant and visible is easier when fewer parts are involved. This light’s integrated red reflex reflector does double duty—giving you the required reflection without needing a separate reflector assembly. It keeps things clean and efficient while meeting FMVSS 108 requirements for safety and visibility.

Dependable on Wet Roads and Ramps: Fully Submersible Housing

Water shouldn’t stop you from getting the job done. The housing and lens are sonically sealed into a single waterproof unit, making this backup light submersible and protected against moisture intrusion. Whether it’s heavy rain or launching at the ramp, it stays sealed and ready to perform.

Built-Tough for Long Life: Shock-Proof Socket and Polycarbonate Body

Road vibration can shorten the life of lesser lights, but this one is built to last. A shock-proof socket guards the bulb against jolts, while the polycarbonate lens and housing handle bumps and rough conditions with ease. The result is a long-lasting light that stays reliable over time.

Clean Mounting Setup: Recessed Fit with Standard Connections

Installation stays simple with a recessed mount design that fits into a 5-1/2" long x 3-9/16" tall hole. It works with an industry-standard molded 2-prong plug (sold separately), so wiring connects easily and securely. The matching black PVC grommet (sold separately) completes the clean, finished look once mounted.

Video Transcript for Checking Out the Backup Light with Red Reflex Reflector

Today, we're going to be taking a look at the Optronics backup light with red reflex reflector. This is a rectangular backup light that's designed for trailers and utility trucks. Going around the perimeter of the light, it's going to feature that red reflex reflector. It's built in. That's going to eliminate the need for a separate reflector. The unit does feature a sonically sealed design, so it's going to feature a waterproof housing and lens unit that is submersible.

The bulb that it uses is an incandescent bulb. There's one bulb on this unit, and that sits in a shockproof socket. That's going to guarantee longer bulb life. We're looking at a polycarbonate lens as well as a polycarbonate housing. It's very strong and durable. When you're ready to mount this, it's designed to be a recessed mount installation with a mounting grommet.

Grommet is sold separately and available, here, at etrailer.com. This light will fit into a 5 1/2" long by 3 9/16" tall hole. It's also designed to accept an industry standard two-prong plug. That's sold separately as well and available at etrailer.com. The unit is Department of Transportation compliant.

It meets FMVSS-108 requirements. Taking the overall dimensions of the light itself, measuring edge to edge this direction, it's going to give us a measurement of about 5 5/16" long. Going this direction, it's going to measure about 3 7/16" tall. The overall depth from very front to very back measures about 1 15/16" deep. The power draw at 12.8 volts is 1.6 amps. We're going to go ahead and hook it up to power. That way you can see what it looks up with some power running to it.

This, right here, is our two-prong plug. Now, on the back you're going to notice that it does have three-prong connections. That's just a standard layout that Optronics will put on their lights. This light just needs a ground wire and it needs the wire for the reverse light. There's three connection points, but only a two-prong plug is needed. We're going to use this connection point, here, on this side. Then on this side, we're using the connection point on the bottom. We'll take our plug, fit it in there. Now, the plug creates a nice tight seal around the connection point, so you don't have to worry about moisture or debris getting in there. This is what the light looks like with power running to it. It's a nice bright light. The clear lens in the center allows plenty of light to come through. Then again, around the perimeter you're going to have the red reflex reflector. This is a reverse light, so when you activate the reverse gear, that light will kick on. When you shift out of that gear, it'll go off. That's going to do it for today's look at the Optronics backup light with the red reflex reflector.

See what our Experts say about this Optronics Trailer Lights

  • Is LED Backup Light BUL35CB Much Brighter Than Incandescent BU33CRXLB
    The difference between the lights isn't in the brightness so much as the clarity, so the Optronics LED Backup Light for Truck or Trailer # BUL35CB is not significantly brighter overall than the Backup Light with Red Reflex Reflector # BU33CRXLB. I have added some photos showing the lights on for some reference, though keep in mind it's not a perfect representation due to camera angle, room darkness, etc. but I wanted to show an example of the different kind of light.
