Hi:
I reread everything and based on the fact that they would work when you hit under the steering wheel, I would say either the switch is bad or there is a loose connection in the steering column. Also, if you could craw under the dash an look where the headlight switch is located, check to make sure the plug to the switch is tight.
Let me know what you find.
