At home the light switches have a dim blue light to be visible in the dark. It seems to be rigged in series with the circuit, so it lights up only when a lightbulb is in the socket. If fluorescent bulbs are installed, they (the bulbs!) will flicker all night long. Also the fluorescent bulbs installed in the bathroom die out very early from the moist. LEDs may be a good solution, but I've yet to find ones that give out enough red tones.
