Purpose

Function

Construction

Operation

1. When the headlight relay (LO) turns on, the discharge headlight control module raises the DC voltage from the battery from approx. 12 V to approx. 25,000 V using the igniter, and outputs it to the discharge headlight bulb.

2. After the discharge headlight is illuminated, the discharge headlight control module converts the DC voltage from the battery to AC voltage (approx. 42 V) using the inverter, and outputs it to the discharge headlight bulb.
