The Switch may be bad. Check the bulbs for the parking lights. Check the fuses / relays for the parking lights.
Check the fuse for the headlights. It is probably open.
Ensure relays and parking brake switch are properly functioning.

The parking lights are turned on when the headlights are on and you pull out on the light switch. The parking lights cannot be turned on by themselves.
The rocker switch on top of the steering column.
behind the battery there are 4 relays it is on the end of the holder it is silver in colour i just replaced one my self
Sounds like the drving light switch is malfunctioning. I would have that replaced or do it yourself then. Good luck. Or see if the parking light switch located on top of your steering column in on.
I would start with replacing the head light switch
