Why would all the lights in a 92 Dodge Spirit work except for the headlights which were just replaced?

The problem could be one of two things. The most comon problem is the multi-function switch, (the swotch that turns your brights on and your signals, and your wipers when the contacts get worn out the headlights may not work,) Also doge had some serious problems with ignition switches, not to be confused with the tumbler this is what the tumbler mounts in.
