Instrument-cluster lighting

The speedometer and the tachometer are illuminated by slit light between the dial face and

the graduated dial. The brightness of the dial-face, needle and display illumination (dim-

ming) is determined by the LSZ light switch center. The lights ON signal is transmitted from

the LSZ light switch center to the instrument cluster (via the K bus). The dimming signal is

also transmitted via the K bus. The LSZ evaluates the following input signals to control dim-

ming:

• Dimmer (knurl in light switch center)

• Photoelectric cell for ambient brightness (in light switch center)

Because the dimming signal is sent via the K bus, there is no need for terminal 58g.
