Warning Lights Manhole (For the prevention of safety accidents at night and in a flooded city, Manhole + Hazard lights signal + Solar cells)
When a manhole cover is separated from its initial place, its round frame starts emitting alarming lights.
This can stop pedestrians from stepping and falling into the manhole 'inside' especially at night and in flood.
While a construction is going on, or our city is flooded, manhole-related accidents happen more often than ever.
This is because of poor safety precautions all over the nation.
