Check your headlight relay, it should click when you turn the switch on and off, if it doesn't replace the relay. if that doesn't work test the headlight switch itself, worst case scenario it will be a bad lighting control module located under the dash to the right of the steering column
How do I test the relay and the switch itself?
Locate the headlight relay and fuse under the hood in the fuse box, have someone feel the relay as you turn on the switch it should click once for on and once when turned off, if it doesn't click and the fuse is good replace the relay. Hopefully that does the trick.
