I have a device which makes a "ping" noise on a piezo tweeter (one of those 10p sized things you get in wrist watches). Is there any way I can connect this output to some LEDs to flash when it makes the noise?

Why do people point to their wrist when asking for the time, but don't point to their crotch when asking where the bathroom is?
