When I have the headlights set to come on auto then turn the car off they automatically go off in about 30 seconds. The same happens when I turn the headlights to the on position because they sometimes don't automatically come on when I want them to. My question is, when I manually turn the headlights on, they turn the car off, the headlights automatically go off in about 30 seconds, just like when I have the headlights in the auto position, does this wear down the battery? If I want the headlights on all the time can I simply keep them turned to the on position with no problems?
