specified limits, vehicle speed sensor switch will send signal to
ECU and on receiving this signal, ECU sends the signal to the
all connected lamps and all connected lamps start blinking.
4) In all the cases, manual over ride by switching ON and OFF, hazard switch, the auto hazard function will get disable.
5) Normal working of hazard switch and lamps connected to the same will remain as it is.
