Re: Audible buzzer

Just returning from a business trip and digest-reading about audible
buzzers: 

I own a 1972 TR6 featuring a two terminal flasher unit. I bought a buzzer
intended as "you're leaving your car with lights on"-indicator and
connected it in parallel with the flasher unit. (A buzzer can be polarity
sensitive, so take care of proper connection if you're trying this at
home.) It sounds only when left or right turn signal indicators are used,
not when the hazard switch is used. The voltage over the flasher unit is
zero with turn lights on or no turn signal selected. Flasher voltage equals
battery voltage with a turn signal selected but turn lights off. The
current through the buzzer is that low that it does not affect turn signal
operation.
Works great!
