Piezo buzzer for LED flasher?
I have built the flasher found here; https://www.instructables.com/id/LED-Flasher-automotive-or-motorcycle/
It works great with the LED turn signal bulbs on my bike I would like to hook up a piezo buzzer to the flasher that buzzes when either the right or left signal light is on (motorcycle flasher reminder buzzer). What would be the easiest way to do it? The flasher runs constantly when the key is on, only powering the turn signals when the turn switch is activated right or left. The buzzer won't work when hooked up to the B+ and load terminals like it was on the mechanical flasher with incandescent bulbs. I figure the problem is that the incandescent bulbs provided the ground for the buzzer though the filaments. Does this sound right? Thanks. Sorry about the long diatribe.
