My newly purchased Saabaru has some odd lighting characteristics. It has daytime running lights, which come on anytime the car is on and the handbrake is down. These daytime running lights are literally just the headlights, with no tail lights on and the headlights themselves only ever so slightly dimmer than normal. When the headlights actually are in the on position, turning off the key and removing it immediately shut down all interior and exterior lights. No parking lights, no gauges, nothing is left illuminated. My question is, since it doesn’t appear that having the headlights in the on position while the car is off actually lights anything up, am I OK to just leave them in the on position all the time?
