When you are with a group of people in the dark but only have one emergency flashlight, it is often difficult to take care of both the front and the back. Therefore, designer Junwon Yang designed a bidirectional emergency flashlight. This design can illuminate in both forward and backward directions. The rear lighting is directed at a 45-degree angle towards the ground, which helps those following behind to see the road conditions clearly in the pitch-black environment. It's a very clever design that effectively takes care of both the front and the back.
