Headlight reminder buzzer add
« on: June 16, 2019, 12:20:56 PM »
Gonna do a small project soon for the hell of it. I recently fixed my seatbelt buzzer, key buzzer and some other little odds and ends for the heck of it which got me thinking about the lack of a headlight warning buzzer. I like driving with at least the parking lights on but have done so and left my lights on at shows enough times that I don’t turn the lights on unless I need them.

My plan is to use an extra buzzer I have around. For its ground, I plan on using the same ground that goes to the key buzzer so the ground circuit will only be closed when the door is open. For the positive side of the buzzer, I’m going to integrate a 5 pin relay so when the ignition is on the circuit from the lights (probably tap into a grey wire or tail light fuse) to the buzzer will be open. Only with the ignition off will the circuit close (pin 87a when the relay is at rest) and send power (from the lights when they’re on) to the positive side of the buzzer. And when the door is open, the ground circuit will close so that when both things happen simultaneously they complete the “loop” for the buzzer to sound.

Probably more work than it’s worth but it should be easy, pretty quick and easy enough to remove if I decide to.

Don’t know how the first link you posted connects and the last link appears to be a diagram showing the door switch and ignition but no product. That’s the key. I’ve seen aftermarket ones that either buzz any time the lights are on and the ignition is off, regardless of door position OR any time the lights are on and the door is open regardless of ignition position. Not sure how the optional buzzer on the 81s are but I wanted it to be like modern cars where the buzzer would only sound when the lights were on, door was open and ignition was off simultaneously. Which is what I accomplished tonight.

The instructions are printed with it. One wire to dash lights, one to fuse panel.
The lower uses a relay to divert the power, could be used with a buzzer or not.
These were just basic examples that may be incorporated.

This is actually a really good idea.  With today's modern cars and their "automatic" on/off, I rarely think about the headlights anymore and can see myself accidentally leaving them on when exiting the car.

An alternative is an automatic shut off circuit so that the lights turn off when you turn the ignition key off, like this product.

Yea that would work too. And be pretty easy to make I’d think. I ended up not tying into the key buzzer directly but found another suitable source.

Short video of it working before I cleaned up the wires underneath. It works exactly how I wanted. It only buzzes when the lights are on, ignition is off and drivers door is open.

It was pretty easy actually. I used a 5 pin relay and an extra seatbelt buzzer I had laying around. A key buzzer or anything similar would work too.

Starting with the relay, pin 86 gets grounded to the chassis wherever you like. Pin 85 is the “trigger” pin that activates the relay. That gets power from any keyed ignition source. I used the Accy blade on my fuse block for that. Pin 30 is the “inlet” if you will. When the relay is activated, whatever is connected to pin 30 passes through to pin 87 or if you have a 5 pin relay like I used whatever is connected to 30 will pass through to pin 87a when the relay is at rest. I tapped into a grey wire (illumination) and ran that to pin 30. Then from pin 87a I ran a wire to one side of the buzzer.

To the other side of the buzzer I tapped into the black wire that feeds into the steering column plug. That wire essentially comes from the drivers side door switch for the dome light. It is the ground that leads to the keyminder contacts in the column so when the drivers door opens it closes the ground circuit.

That’s it. The buzzer now only sounds when the lights are on, ignition is off and the drivers door is open. In this configuration, any time my ignition is on the relay is activated but I don’t even hear it click when I turn the key on/off.

I’m glad I’ve gotten some positive responses. Part of me thought it was a waste of time doing it let alone posting it. Then again it didn’t take long at all. And I haven’t driven the car since but I’m happy that I can use my lights now without worrying about leaving them on.

Interesting idea!  GM offered that in 81, and they did it exactly the same way, but the relay and the buzzer were made into one block.

That's really cool. I'll either do this or the auto on headlights.  I know you spelled it out but could you scribble out a diagram? I think it would be helpful for me and future searches.  It's a great idea.

Really? I knew it was an option on 81 but I couldn’t find any other info on them.

I can’t imagine auto lights would be too difficult to do either. As far as the diagram I can definitely do that if you or someone else are willing to post it. I don’t have a photo hosting account.

Huh, neat.

That was very quick! And that was all done with a relay and minor re-wiring in the fusebox area?

Not even rewiring really. Just tapping into some existing wires. Dash illumination, the ground trigger for the key reminder and keyed ignition power. Plus a ground.

Got your message and thanks. I just sent it. After photobucket screwed everyone around I deleted my account. Before they started allowing photos again with their watermark. I tried another hosting site but it wasn’t very user friendly so I gave up on it.

I saw an old motorcycle one time (before they had auto headlights) that the guy posted a handwritten note taped to the gas tank,
"Lights on Stupid". I thought that was pretty good. LOL

Ha! Hey it probably worked. You know that guy came back to it with a dead battery more than a few times.

No problem Form. And thanks to Aus for posting it.
