  1. The lamp light source is by the arch discharge by applying high voltage into the xenon gas-filled bulb instead of the halogen bulb filament.
  2. Sight becomes more natural and brighter because the amount of light are gained adequately and the color of light is sunshine-like white.
  3. The xenon bulb drops the amount of light, repeats blinking, and illuminates in red if the bulb reaches the service life.

Scheme 208: ILLUMINATION PRINCIPLE
Scheme 208: ILLUMINATION PRINCIPLE
  1. Discharging starts in high voltage pulse between bulb electrodes.
  2. Xenon gas is activated by current between electrodes. Pale light is emitted.
  3. The luminous tube (bulb) temperature elevates. Evaporated halide is activated by discharge. The color of light changes into white. NOTE: Brightness and the color of light may change slightly immediately after the headlamp turned ON until the xenon bulb becomes stable. This is not malfunction. Illumination time lag may occur between right and left. This is not malfunction.
