    I thought the headlights turned on with the key off on *all* Volvos. They're always sleeping with their lights on, like the bogeyman is gonna get 'em.

    Check the wiring harness at driver side front. More then likely you have some wires that rubbed and grounding out.

    Yup on high beam across from you. Or low beam with one of the two lights aimed way up in the sky. Soooo stupid.

    Also, unplug your headlight switch and see if that has any effect.

    My tail lights etc were staying on when switched off - unplugged the switch and they went out. $218 CAD for a new one and all good..... you'd think it was made of platinum though. Stupid OEM parts
