Features to know about

Reliable Marker for Wider Trailers: Mini Identification Light Bar

When trailers stretch beyond 80" wide, staying visible to other drivers becomes more important than ever. This Peterson Mini Identification Trailer Light Bar takes care of that with three amber incandescent lights across a 16-5/8" long, 1" tall bar. It’s built specifically to serve as a rear identification light, keeping your trailer compliant and easy to spot in low light or at night.

Built to Last on the Road: Durable Powder-Coated White Steel Base

Corrosion and wear can ruin a light bar fast, especially when it’s exposed to moisture or road grime. This one uses a powder-coated white steel base that’s designed to resist rust and keep its finish looking clean. It’s made for long-term reliability and steady performance wherever you tow.

Straightforward Surface Mounting: Single-Wire Design

Installation doesn’t need to be complicated. The surface-mount setup lays flat against the trailer and secures using standard mounting hardware (not included). All it needs is a small wiring hole and two mounting points spaced 16-1/8" center to center. Its single-wire design grounds through the mounting hardware, making wiring simple and clean.

Serviceable and Compliant: Replaceable Bulbs and DOT Approved

Each of the three Peterson 107A lights uses a 194/193 bulb that’s easily replaceable when needed (part 422400 sold separately). The assembly meets DOT requirements, so you can trust it for highway use. It’s a straightforward, dependable setup with a 1-year limited warranty backing it up.

  • Looking to Replace Kaper II 1A-S-1700A Amber Identification Light
    Hey Mandi, I looked up the Kaper II 1A-S-1700A and found that it is an amber identification light that measures 17.45 inches long and 2.2 inches wide. We don't have anything that's an exact match with the Peterson part # 427800 being our most similar option. This measures 16-3/4L x 1-3/8W Inch and instead has three smaller amber clearance lights. Would that work or do you for sure need a solid light?

  • Does The Peterson LED Identification Light Bar M191-3RL Come In Amber?
    Hi Corey! There is an option with incandescent lights with the Peterson Mini Identification Trailer Light Bar - Incandescent - White Steel Base - Amber Lens # 427800, but there does not look to be an amber option available with LEDs. However, you may be able to mount something like the Optronics LED Trailer Clearance or Truck Cab Light - Submersible - 15 Diodes - Triangle - Amber Lens # CBL22AB to your existing bracket. It would need to be wired up, of course, but I think it would work....

  • Color Options for Peterson Mini Identification Trailer Light Bar
    The Peterson Mini Identification Trailer Light Bar is available in both amber as part # 427800 and red as part # 428000. I recommend using the same color that came on the trailer previously but if you wish to change colors, you'll have to look up your local laws and regulations in regards to trailer lighting codes.

  • Amber Light Bar About 16 Inches Long for Trailer Clearance Light
    We don't have an amber colored light that's exactly like the # MCL78RB you referenced. The closest I have is the Peterson Mini Identification Trailer Light Bar item # 427800, which measures 16-5/8" long and mounts on 16-1/8" centers. Note that this is also an incandescent light, not LED.

  • Recommended Clearance Light Bar for Front of Ford E-450 Box Truck
    The lights that are on the "mom's attic" portion of Ford E450 are either incandescent light bars like # MC99AB. We also have the LED option # 427800. These all will work well with the front of the box truck above the cabin. If you have a different style than this, take some dimensions and let me know so I can check compatibility.

  • Is Optronics Sealed, Streamline LED Trailer Third Brake Light Available in Amber
    Optronics does not make an amber version of light # STL80RB but they do have a identification bar # MC99AB that is 17 inches long overall and the mounting holes at 16 inches apart on center. Another option that will match up to your existing mounting holes is the Peterson Mini Identification Trailer Light Bar # 427800. This one is slightly shorter at 16-5/8 inches overall, but will definitely cover up the existing holes that are 16-1/8 inches on center.
