odometer light and radio

If one has a bad ground, it could be using the other for a circuit connection. Usually it's the dash light with the bad ground. Could also be a bad headlight switch- do the parking lights also stay on with the others?

no every thing else ok but the alarm (which i dissconeected the horn from it) goes off while driving and i hear the directional (tick) alot iam thinking that has something to do with it ....

problem solved ..when i put it in park positio i had to hear a click and everything is fine
