Headlamps wont go on relay problem?

What is your question?

While driving, my high beams were on, the lights went out,(Side lamps, blinkers hazards all sill worked) I franticly jerked the high/low switch on the steering wheel they came back on went out again and now they dont come on. The switch turn the inside lights and side lamps on they are all fine. DOnt know if it needs a relay and where that would be, or if the problem is in the high/low switch on the sterring column and how to replace that thanks
