Usually in the driving handbook, it tells you. Please correct me if I am wrong. I believe that headlights are turned on in the early hours of the morning and at dusk time (late afternoons and evenings)
Your headlights turn off when you turn the high beams on because you have a defective switch. You need to have a mechanic replace the high beams switch. It is a simple replacement.
It depends upon driving condition (not time)
There are a couple of different times when you'd turn off your headlights. You'd turn off your headlights when the car is off for example.
you dont,
headlights and dash lights in 2001 sunfire wont turn on.
Your headlights need to be adjusted, you do this by popping your hood and adjusting them by the screws on the top or bottom of the headlight, most of the time you will need a screwdriver to do this.
Headlights not working
do the headlights come on automatically or manually, if manually turn off
30 mins. before sundown
Perhaps you need to check a fuse.
i would assume you need to turn your headlights off as they are the most common reason for the beeping after you turn off the car. My headlights are off and the car is still beeping
If your headlights wont come up when you turn the lights on then you will have to "turn" them up manually.......look under your front end for the box that controls your flip up headlights and find where you need to turn/crank to get them to come up manually. Remember though, they will be up permanently unless you crank them up and then back down all the time.
