Lights On Buzzer

I was wondering, how do you fit a little piezo buzzer that sounds when you’ve left your lights on but switched off/keys out?

I’m getting old and forgetful and keep missing the little green sidelight tell tale - my name is in my shirt just in case.

Any Sparky Boffins with an idiots guide?

Shirley a simple relay and buzzer will do it?

Quite probably, but Electrics are wizardry to the likes of me!

Just off the top of my head

I got one from vehicle wiring products years ago which came with simple wiring instructions.
Triggered by the door switches .

I’m useless at electric string and wiggly amps, but as @Scooby22 says a simple relay energised by the ignition will suffice. I suspect you just need to track down the correct wiring to butcher

It looks like hieroglyphics to me, unless there is a numpty picture with colours and a nurse on standby it will end in tears. I’ll put the buzzer I have back in the box marked ‘nice ideas’ and move on to hammer/spanner opportunities
