Light Bulbs in circle

In a circle are $n \geq 2$ light bulbs numbered $1$ through $n$, all initially on. At time $t = 1, 2, 3, \ldots$ you examine bulb number $t$, counting around the circle (so after bulb $n$ comes bulb $1$ again). If it is on, you change the state of the next bulb around the circle, bulb $t + 1$ (bulb $1$ if $t$ is bulb $n$); i.e., you turn it off if it's on, and on if it's off. If the examined bulb is off, you do nothing. If you continue around the ring in this manner, will there be a point when all the bulbs are on again?
