Lighting the lamp

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.

There is normally a 3 second delay between activation with the light switch or ignition on and the lamp coming on.

As with normal headlights, the lamps remain off while the starter motor is cranking and come on once the engine is running.
Each time voltage is supplied to the ballast, 3 one-second attempts are made to light the lamp.
