DESCRIPTION AND OPERATION 88-15
Instrument illumination
Dimmer switch
The instrument pack contains 3 bulbs to illuminate the dials. Depending on market the bulbs are illuminated either
from the side lamps feed with no dimmer control or from a PWM dimmer control located on the dashboard. A PWM
dimmer is used so finer control of the instrument illumination can be achieved.
The input is either direct from the side lamp power feed or from the PWM dimmer control. The instrument pack
provides the earth path to illuminate the lamps.
