Features to know about

Brighter Light, Less Power Draw: 10-Diode LED Design

Old incandescent lights can’t compete with the clean output of LEDs. This Optronics Double Bullseye light uses 10 efficient diodes that shine bright while drawing just 0.087 amps at 12.8V. The red lens covers white LEDs that deliver consistent light without burning hot or dimming over time. You get reliable visibility that keeps power demand low and never needs bulb changes.

Lasting Durability in Tough Conditions: Polycarbonate Housing and Lens

Cracked lenses and corroded sockets are a thing of the past. The durable polycarbonate housing and snap-on lens resist impact and wear, keeping the light sealed and intact through road spray, vibration, and long hauls. With no brittle filaments or glass bulbs to worry about, it’s built to hold up over years of use.

Clear Visibility from Every Angle: PC-Rated Beam Spread

When safety depends on being seen, this PC-rated light delivers. The design projects light 90 degrees to either side for a full 180 degrees of coverage. Properly mounted, it doubles as both a clearance light and a side marker—bright enough to be visible head-on or from an angle so others can spot your trailer’s edges at night or in low light.

Straightforward Mounting and Wiring: Surface-Mount with Self-Grounding Setup

Installing this light is simple. It mounts flat against the surface using a flange or bracket—no need to cut holes or recess the fixture. The distance between mounting holes is 3 inches center-to-center, making placement easy to line up. The 1-wire design grounds through the mounting hardware itself, so you only connect a single power wire. Clean, quick, and secure every time.

Unique Look That Stands Out: Double Bullseye Design

Beyond its performance, the double bullseye pattern gives this rectangular 4-1/16" x 2-1/8" light a standout look. It’s a small touch that makes your trailer lighting system look sharp while staying functional and road-legal—proof that practical can still look good on the road.

Product is great my customer service rep Katie D was even better. I ordered what I thought I needed she called me to follow up and found out what I ordered was incorrect she found the correct product for me. Looking forward to doing more business.

Fast deliver, high quality product, separate grounding not needed. I replace the broken units on the trailer in minutes,



by:

Works great and fits into the supplied mounting brackets. BK42CB. It would have been helpful to get Brass or Stainless mounting screws with them.

eTrailer always has the parts I need for my trailer projects.

Took some time to wire 3 of the lights, and it worked perfectly. Definitely a lot brighter. Will order these lights again

One year later and still nice and bright. No fading or hazing on the lenses. Perfect replacement for the original lights on my Fruehauf/Jartran cargo trailer.
