I dont know how to get my light to work?

I have a 98 Lincoln Continental and i had a Dim out on my head lights and i changed the bulb already and it still doesnt work. Is there a trick to make it work? Idk i just thought i%26#039;d ask and see if theres anyone out there that can help me.|||Might want to check the contacts where the bulb goes, they may need to be cleaned. Also you may want to check the fuse.|||If it doesn%26#039;t light at all, check your fuse and check the wiring to see if its disconnected or faulty somewhere.
