Red Flag Lamp / Rescue,Lamp,Prompt

Red Flag Lamp

In our daily life,some cars often stop emergently in the highway because of vehicle fault. At this time, we need to place a warning sign behind the car about 100m-200m. However, the process of placing the warning sign is dangerous. So, combining shadow-casting technique, we design a king of red flag lamp to solve this problem. We can put it on the roof or the trunk lid. When the lamp is open, the words, "slow, be careful", can project on the ground to warn drivers to slow down and detour.
