Wiring a headlight buzzer

[hakeem43020]

Hello all, getting tired of leaving my lights on. Is there anyway to wire a relay to get the OEM buzzer to chime when door opens if lights are left on (Like newer cars)? Would something like this work?

Tried it today but the buzzer chimes when the lights are off instead of on and turns off when I switch them on (opposite of what’s expected).

Diagram didn't work but I figured it out after toying with it again today. The buzzer now chimes if the door is open and the headlights are left on like in the e39/e46 etc.

Great,
What did you change?
Does the diagram need to be updated?

Thanks, Roger

The buzzer is ground activated so the first diagram won’t work.

85 & 30 go to the door switch. You’ll have to take the front speakers out to access it (There are a bunch of wires that run there. It’s not in the bunch of wires. It’s in the bundle with two wires taped together. Green/Brown wire I think).
87 to the parking light wire (must be the parking light wire since the headlight wire loses power when the cars off). I took the easy way and spliced into the light bulb (the one left of the knob since it’s easier to access) beside the knob that comes on when you pull it out. That gets 12V as long as it’s on.
86 to the buzzer + wire. If you connect a ground to this wire it should activate the chime.

i also wired an inline fuse on mine just in case.
