Simon -
The Durasparks are reliable, unless you do something silly, like leave the ignition on the "On" postion for a long time with the engine OFF.
(Note: This behavior is bad for other ignition parts too, like oil filled coils, which have been known to burst when overheated.)
I did that because I don't have any buzzers hooked up in my car (Ignition or Seat Belt).
I am actually looking for a simple circuit that gives me an "Ingition Buzzer" that gives me buzzing when the engine is OFF, but ignition is ON, that:
1. Is simple
2. Ties into existing L Wiring without disabling other functionality
3. Looks clean
4. Is inexpensive
Just the challenge for someone like JFB!
