Headlights go out...

I have a problem with my 99 Dakota Club Cab.
While driving I switch the headlights from high to low beams and the lights go out. Does anyone know if this problem lies in the light switch or the high beam selector switch?

sounds like the switch to me.

I also have the same problem with my 99 club cab - This didnt start happening until i took it in for service at a dodge dealer shop though
