Xenon headlamp, location/function - GF82.10-P-2001A

WARNING: This page does not describe the selected car, but rather 42 other vehicles, including the 1999 Mercedes-Benz S600, 1999 Mercedes-Benz S500, 1999 Mercedes-Benz S420, 1999 Mercedes-Benz S320, and 1999 Mercedes-Benz CL600. However, it is still accessible from the selected car via links, so may be relevant.

MODELS 129, 140, 202, 208, 210, 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.
