Light Switch

Light Switch

Brief description of components

Light switch
The light switch consists of
- Rotary switch for sidelights and low beam (and special equipment Automatic Light Control)
- Two buttons for fog lights and rear fog light
- Potentiometer for dimmer of panel illumination
- Potentiometer for manual headlight beam height control in the case of halogen headlights







S_SL = interior switch for sidelights
S_AL = interior switch for low beam
1 = interior switch closed (after 5 V)
0 = interior switch open

Depending on the vehicle equipment and country variant, different light switches are fitted:
- Switch for vehicles with xenon headlights and automatic headlight beam height control (LWR),
- Switch for vehicles with halogen headlights and manual headlight beam height control (LWR), This switch has a potentiometer for manual headlight beam height control (can be operated using a knurled adjuster).
- Switch for vehicles with Automatic Light Control. The rotary switch has an additional switch position FLC for the Automatic Light Control as well as a light emitting diode.

Power supply: The switch is supplied with 5 volts by the light module.

If the power supply is defective, the light remains ON: the light is automatically switched on if
- the cables to and from the light switch have been cut or
- are switched to ground
- are at 12 V.
- For safety reasons, the light switch can only be switched OFF if there is 5 V at both switch outputs to the light module. If a short circuit means that there is once 5 V and once 12 V, the light can not be switched OFF: low beam and Automatic Light Control remain ON.
- high beam and headlight flasher only run if the steering lever is held
- The indicator only runs if the steering column lever is held. no continuous flashing, no automatic reset.
