Answer 1

if it started out nice and bright and then started going dim and is now out , i'd suspect a ground problem. unless it's some kind of fluoresent bulb, bulbs don't go bad gradually. check your ground wire and or tapping on the tach (not to hard). other wise take it apart and make sure bulb is tight in it's socket. still not working ? try a new bulb. you can check the old bulb if you have a continuity tester. also look at the filament with a magnifying glass.
