1. Electrical Control: The hazard light activation lever sends an electrical signal to the car's electronic control unit (ECU) responsible for managing the car's electrical components.
2. Relay Activation: The ECU then triggers the hazard light relay, which is essentially an electromechanical switch.
3. Power Distribution: The hazard light relay routes power from the car's electrical system to the front and rear hazard lights.
4. Dashboard Indicator Illumination: The ECU also activates the hazard light indicator on the car's dashboard, indicating to the driver that the hazard lights are turned on.
5. Simultaneous Activation: The power supply sent by the relay switches between the left and right indicator circuit, resulting in the alternating blinking of the front and rear hazard lights.
6. Alternating Current (AC) Supply: The hazard lights use AC current rather than DC current used by other electrical components in the car. The ECU provides this AC current to ensure the lights flash.
7. Continuous Operation: Once activated, the hazard lights will continue to flash until they are manually turned off by pressing the hazard light lever again.
Overall, the process involves a combination of electrical activation, relay operation, and distribution of power to the front and rear hazard lights, resulting in their alternating blinking and providing a visible warning signal to other road users.
