E30 Zone

Hi, I'm trying to install a warning buzzer to alert me when I leave the lights on. I had one installed on my Mazda that used a cheap buzzer from maplin that linked the headlight fuse to the ignition fuse. So when you switched off the engine/ ignition the buzzer would sound.

Now I cant work out which fuse is the ignition, so cant seem to get it to work.

Any ideas? Suggestions?

Cheers, Nathan

This looks like a good start:

One day I'd like to do one too - flattened by small battery twice now

The circuit in the link above will work fine, but substitute parking/side light for headlight, since a) the headlamp switch is earth to operate, and b) you can't leave the headlamps on if you have an E30, since they only work with the ignition on.

I've buggered about with my ignition (to effect a cut off switch and ignition button) so somehow I've bypassed that little feature
