I recently changed my headlights and a few days after I changed them I noticed that my dash lights would not come on. The dome light will not come on when I open the door but will work by switching it on manually. Also the alarms for lights left on and door ajar don't work. I know the dash lights are working becase my ebrake light comes on as well as various other lights but not lights for the tach and spedometer. I need help I am already tired of driving with no idea how fast I am going at night.
