    Heya'll:
    I asked this question in another post of mine as a follow-up question, but the issue really deserves its own post.

    I have been spoiled by automatic headlamps and keep forgetting to turn off my headlamps. Is there a way to rig up a headlamp warning sound?

    @Jigs-n-fixtures shared MACs Auto Parts 41-73955 Headlamp On Warning Kit https://www.amazon.com/dp/B071LJT7FL/ref=cm_sw_r_cp_tai_Ad.zEb6QK8A7J, but I'm curious if there is a way to set up a circuit that if the headlamps are on and if the automatic cab light comes on, then the transmission's Reverse ding will sound?

    Any input is appreciated. I'm on corona time right now, so I've got the chance to tinker.

    You could do exactly that with a relay as long as you can find the right wires. I'd have the dome light close the relay and the headlights supply voltage. Only down side might be that if you turn on the dome light at night you'd have your beeper going. Often door switches are switched ground, so pay attention to continuity.

    There are a few ways of doing it. And, if you have the wiring schematic to work with. If you don’t you’ll drive yourself nuts trying to figure it out. Sometimes it is far more effective to buy an off the shelf product, than reinventing the wheel.

    If you did a google search you might find the old plans that the magazines like Popular Mechanics during the seventies.

    The easiest thing to do is cross the parking light circuit to the ignition circuit with a peizo buzzer. If both are powered, there is no ground, buzzer quiet. But leave the lights on, then the ignition is off, and the buzzer seeks ground through the ignition circuit. This is exactly how a battery light functions as well.. I've had to do this a time or 2 for people

    $8 for 2 buzzers https://www.amazon.com/Icstation-85dB-Active-Piezo-Electronic/dp/B01LAYWUDO

    The little Piezo buzzers are the handiest thing going as a short finding aid. I kept one in my tool box for years. Just clip it in place of a fuse that is blowing and then go about tracing for the short. It will buzz until the short is eliminated so you don't have to keep an eye on it as you would a test light.

    Oh my God Fred, you just reminded me. My friend Tim and I used that, when we were tracing the electrical problems on my mini truck! He introduced me to it, and your right. What a time saving aid it is! I never knew the name of it other than a buzzer! LOL:) Once again you taught another old dog a new trick! LOL:D
