A chime sounds nice
Thomaspin has a description on his website of how he spliced a Radio Shack buzzer into each of his turn signal flashers. Being as when the air is blowing and/or the radio is on I can't hear the clicker, this sounds like a great idea. A chime would sound even better.
How big is the chime?
