Mazda CX-5 Service & Repair Manual: Discharge Headlight Bulb

Purpose, Function

Construction

Operation

1. When high DC voltage (approx. 25,000 V) from the discharge headlight control module is input to the electrodes, the insulation between the electrodes is broken down and electrical current flows between the electrodes.

2. When electrical current flows between the electrodes of the discharge headlight bulb, the xenon gas is energized and emits light.

3. When the xenon gas emits light, temperature inside the discharge headlight bulb rises, the metallic iodide vaporizes/separates, and the metallic element discharges and emits light.
