If a fluorescent light blinks is the light bulb bad or the ballast?

I have seen it both ways. Usually it is the bulb which is a few bucks. The ballast will cost more and could cost $15-$30 bucks depending on type. If you have another bulb that is working, swap it with the flicker light and see if the problem goes away. If the swapped bulb works, I always put the bad bulb in the fixture where the good bulb came from. If the bad bulb now works, you could have a seating problem with the bulb. If it flickers, replace it.
