The Stovebolt Site Forums The Shop Area The Electrical Bay Headlight Buzzer

I was chatting with tclederman (Tim) the other day, and he said wouldn't it be nice to have a buzzer that would sound if you had left the headlights on? I thought it would, as I have run down the battery numerous times over the years by doing this.

Anyway, I thought about it a bit and came up with a simple relay circuit that would sound a buzzer if the headlights were on and the ignition was off.

Here is a link to the circuit diagram.

Basically the way it works is that a buzzer is wired through a relay with power for the buzzer taken from the headlight side of the headlight switch. The relay is operated by the ignition switch such that if the ignition is on, the buzzer is disconnected. If the ignition is off and the headlights are on, power will flow to the buzzer.

Enjoy.

I'm offline for the next 3 days, but I'll make a better diagram when I get back.

Having something like that connected to my dome light would have saved me a considerable amount of hassle in the past.

Been there; done that.

I don't know if they still do but they use to make something like that. I had a 72 chevy impala in the '80's my now ex use to leave the lights on all the time, found a head light buzzer at the local parts house, no more dead batterys

I used a circuit similar to that to power a loud buzzer connected to the turn signals for a customer who couldn't hear the click of the flasher. He would drive for miles with the turn signal on at times, and he got tired of his wife fussing about it!

Kurt,
What relay are you using? Is it 6V?
Thanks,
