My light has 2 or 4 bulbs 2 of them flash on and off 3 times then nothing else but one does it then the other why?
When they turn on do they blink and take a second to warm up? If so they are florescent. These bulbs often have ballasts in the fixtures that go bad after time. If they aren't florescent and the problem continues after replacing the bulbs you could have a wiring issue.
