I have a lighted switch in my bedroom (little green light comes on when the switch is off to make finding it in the dark easier). When I turn my light off, the light is flicker-y for 30 seconds to a minute, then stays off all together. Is this a sign there is something unsafe? Should I have it replaced?

I don't suspect that it is unsafe, particularly if there is no burning smell and you do not hear any sizzling.

More than likely the pilot light in the switch is getting ready to go "toes up" and the switch should be replaced.

Thanks. Bought a new switch today.
