Input voltage drop detection function
If the input voltage of the gas discharge headlight control unit (9-16 V) is less than normal (except for the voltage drop immediately after the headlight is turned on), the control unit switches off the gas discharge headlights for protection purposes.
The gas discharge headlamp control unit switches the headlamps back on when the normal operating voltage is restored.
Input fault detection function
When a deviation from the norm is detected at the system output (open or short circuit in the wiring harness circuit), the control unit switches off the gas discharge headlights.
If the gas discharge headlight control unit has been triggered due to anomalies in the system output, the headlights remain off until the exterior lighting switch is set again to the position corresponding to the headlights being on.
