220 up to 31.08.01 with CODE (612b) xenon headlamp unit
When the low beam lamps are switched on the xenon headlamp control module (E1n1, E2n1) activates the xenon headlamp control module and ignition module (E1n2, E2n2) via the control voltage within a few milliseconds.
A high-voltage surge from the ignition device ignites the xenon lamps, and in doing so an electric arc is formed between the electrodes. When an arc of sufficient stability is detected, the control electronics of the xenon lamp control module (E1n1, E2n1) switches over to power-limiting mode.
A voltage transformer generates the voltage required for reliable xenon lamp operation.
For technical reasons the xenon lamp has a timed startup characteristic. After switch on, 50 % of the luminosity is reached within 1 to 2 seconds and full luminosity is achieved after another approx. 30 seconds.
