Using information gleaned from the Internet instead of an array of sensors, the TrapTap Speed Trap Indicator aims to warn you of red light cameras, speeding traps, and other potential pitfalls. The small circular gadget connects to a companion app over Bluetooth, and lights up red near red light cameras and school zones, blue near police and mobile radar traps, and green near speed zones. The app has a built-in database covering every red light camera and school zone in over 60 countries, and relies on users to double tap the indicator’s single button when they spot a speed trap, thus alerting others to its location. Unlike radar detectors, its 100% legal, and is easy to move from car to car thanks to a reusable, sticky pad on the bottom.
