The FLIK Peacemaker is a lit LED sign that mounts inside a rear window and displays a thumbs up or a thumbs down, triggered from a small remote you keep in reach. The practical version of the pitch is that most road interactions do not have a way to say thanks for letting me merge, and a lit hand gesture reads clearly at night from several car lengths back. It mounts with the included double-sided automotive tape on any smooth interior surface, so it works in a car, truck, SUV or RV. Adjustable brightness keeps it from washing out a rear view mirror behind you. Best fit: commuters, road trip cars, and gift lists for the person who narrates traffic.

Pros

  • Remote trigger means you never take a hand off the wheel to reach it
  • Thumbs up covers the merge-thanks case that headlights and a wave do not
  • Adhesive automotive tape mount works on any smooth interior surface
  • Adjustable brightness so it does not blind the driver behind at night

Cons

  • Check your state and local rules first, since some places restrict illuminated signs in rear windows

Frequently asked questions

Is it legal to use?

Rules on illuminated rear window displays vary by state and locality, so check your local vehicle code before installing.

How is it controlled?

A small wireless remote you keep within reach, so you can trigger it without reaching for the unit itself.

Can I adjust the brightness?

Yes. Brightness is adjustable, which matters at night so you are not glaring at the driver behind you.
