Guide in dark / Non-slip rubber strip

In the power-outage or low-light situation, one can only grope down stairs slowly. It is inconvenient and dangerous.
GGuide in Dark can solve this problem. It looks like an ordinary non-slip rubberstrip, but the built-in LED lights glow when someone steps on it. Meanwhile the signal is transmitted to adjacent two rubberstrips and makes them glow too. This technique provides convenience and safety for pedestrians walking on the low-light stairs. Guide in Dark doesn’t require external power supply to provide energy.It can change the pressure of pedestrians’ steps into electrical energy to provide power for LED lights.
