Whenever asked what road humps are designed for, we will refer to its important functions in reducing traffic accidents by requiring the drivers to slow down. But how do they work in the night? I mean, there’s only dim light on the road and the drivers couldn’t always notice the road humps from far away, and as a result these speed breakers won’t work that effective as we’ve expected.
Fortunately some designers have thought of that question earlier and they’ve teamed up with the ‘Self-powered Safe Hump’ which is equipped with LED bulbs and therefore gives off light in the dark. Moreover, all the energy needed by the system is converted from the mechanical energy generated when the car passes by.
