Warning System Road Reflectors provide enhanced safety in the event of road accidents by giving other drivers an immediate visual signal. The connected beacons can be user activated with a simple twist following a crash or even a simple car stall. Activating one will trigger all the reflectors in a designated vicinity to turn on, thereby warning oncoming traffic to slow down in order to avoid a pile up. The system is particularly useful in blind curves where drivers may not be able to brake in time. Designers: Chung-Tung Lin, Yu-Han Lai
