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
