Its the same principle as a welding arc. when the bulb goes out the philament breaks into two pieces. When they split apart, before they get too far apart, the electricity jumps the gap causing a bright flash. After that the current cant make the leap so the bulb is dead.

The bulb burns out because the filament breaks. Current cannot stop instantly, so an arc will form at the point of the break, and once started will follow the ends of the filament as they fall. This is the flash you see.

Because 9 times out of 10 the light goes out when you are turning it on. The sudden rush of electrons causes the light to come on for a split second, but the heat change breaks the filament causing it to go right back out.

The light is produced as electricity passes through the filament . The resistance to electrical flow thought that filament is what generates light energy. For that brief moment at breakage, the resistance to current flow increases dramatically and the light output increases in relation to the increased resistance.

because chuck norris is so fast that he runs to your light bulb and breaks it in a flash

Because of the arc of current as the element breaks ...

when a lightbulb goes out the filament basically bursts, thus creating the small flicker or explosion if you will that occurs.

Because the fillament bursts.
