How do you turn on the dashlights in the 92 Mercedes 190e?

To turn on the dash lights in a 1992 Mercedes 190E, locate the headlight switch on the left side of the dashboard. Rotate the switch to the right until you hear a click, which activates the parking lights and dashboard illumination. If the lights still do not turn on, check the dimmer switch (often integrated with the headlight switch) to adjust the brightness of the dash lights.
