Take charge of your MINI's driver-controlled lighting and signaling with the Standard Ignition Multi-Function Switch (MPN CBS-1639). This combination unit bundles three jobs into one assembly — headlight on/off, high/low beam (dimmer) selection, and turn-signal actuation — and drops in as a direct-fit replacement for the 2005-2008 MINI Cooper (All).
- Three switches in one: combines the headlight switch, dimmer switch, and turn signal switch into a single service part.
- Headlight & dimmer control: switches the headlights and selects between low and high beam.
- Turn-signal function: actuates the left/right turn signals for the driver.
Because it is one integrated assembly, a fault in any of the three circuits can call for replacing the whole switch. Signs this part may need replacing include headlights, high/low beams, or turn signals that respond intermittently or not at all when you operate the control. Because those symptoms can also stem from wiring, bulbs, relays, or the signal flasher, diagnose the cause first; if the multi-function switch is at fault, this replaces it.
Listed under three catalog names — Headlight Dimmer Switch / Headlight Switch / Turn Signal Switch — for the same combination part.
Manufacturer part number CBS-1639 (also CBS1639).
