This Dummy Needs a Headlight Buzzer

[Gasasaur]

Does an '87 Silverado have a warning buzzer for leaving the headlights on? If it has one, it doesn't work. And after this weekend............I think I need it.

[68Timber]

Napa carries them.

Oem?

[Gasasaur]

I guess my point was missed. I didn't know if the truck was supposed to have a warning or not. Evidently it is and mine doesn't function. Good to know it did originally come with one and I can get it locally. Thanks.

[68Timber]

No sorry, they never had headlight buzzers, not that I'm aware of anyway. Napa has an aftermarket buzzer for a few bucks, I've installed them on both my squares.

[LDO]

I have actually been looking into this. I believe the Silverado models (I have an 85) came wired for all the buzzers (headlights, key & seatbelts). The difference is in the buzzer module itself. You have to pull it and see if you have a 7 pin module or not. The 7 pin is the one that will buzz for key, belts AND lights. The other one (the one I have) has 4 pins and will only buzz for key and belts.

It is located over by the gas pedal.

I plan to go to a junk yard and look for a 7 pin one.

There are several GM PNs to look for:
22535998
22533568
are just two of them. These modules were used in other GM vehicles as well.

There are a few on EBAY but they want too much for them when I can pay a buck to get into the yard and the fella behind the counter will prolly just give it to me or ask for 3 bux.

None of the parts sites I've found carry them anymore.

Now you know everything I know about this.

[Gasasaur]

Well LDO, I don't know if you've done anything else worthwhile with your life, but if nothing else, you are a SBCBG (square body courtesy buzzer guru) in my book.

I wish that would get you a cup of coffee, but I'm afraid it's not in the cards

Thanks for the great help.

UPDATE:
I was wrong about the pin count. My old one is a 6 pin, the one I (we) need is a 7 pin.

Here are pics.

1st pic is my stock 6 pin that has no headlight tone.
2nd pic is a 7 pin unit out of a 97 Silverado.

As soon as I popped it in and turned on my headlights, I got tone!

I installed one of those on my sons truck, works good...

[b454rat]

I had a 79 Malibu that had one, I'd think it be an option in the 80s....

This is a great thread. I asked about this quite some time ago and everyone questioned why? When your daily drivers have had auto cut off for many years, turning the lights off and on is no longer instinctive. If your like me and love the look of park lights at dusk, its easy to leave them on.

Does anyone know what year they added the socket to our trucks? Where exactly is this socket?

[LDO]

over by the gas pedal. it's a panel with a flasher looking thing, this module and another larger module which may be the cruise control.

I can take a pic when i get home tonight unless someone else beats me to it.

I found it, but didnt get any pics. It appears to be multi function with a connector for the "convenience reminder buzzer" and the cruise control module.

I suppose it wouldn't be too difficult to design a little delay module that can turn your lights off automatically.

It would be slightly more difficult (though not impossible by any stretch) to design something like modern cars, that would leave the lights on for an additional 30 seconds or so if you turn them off after you turn off your ignition.

Late 70's and early 80's Caddies had this feature plus they had a really cool headlight chime that sounded like something out of an elevator or hospital. Trouble is, they're a little GM box with multiple inputs that don't easily relegate them to retrofitting into alternate platforms

The linked item should work perfect for a 30 second delay of your headlights. It's a rather powerful little item. I used one in designing a 12v school bell system, but have not used it on a truck yet.

Even though it's labeled for 10 amps, I wouldn't run the headlights through it directly. Instead, wire it up to control a relay.

I realize this is an old post, but I thought someone may still be interested in this.

This is how I have a 22535998 chime module hooked up on my 75 C10 to let me know that my lights are still on.

When I open the door with the head lights or parking lights still on the module will chime. I had to hook this up after coming out of stores to find a dead battery because I forgot to turn the lights off.

Run a wire from the door jamb ground switch to pin 3 and over to pin 6 on chime module.

Run another wire from the top plug on the head light switch to pin 7 on the chime module.
The top pin on the head light switch has 12 volts on it when the parking lights or headlights are on.

By using the door jamb switch as ground for pin 3 & 6 the module does not need 12 volts constant power to make a chime.

Good deal ! .

The fleet mechanics @ work used to ysnk these out without being asked, many of the drivers were pissed off because they'd forget....

I'm old now so what is there for us DEAF guys ? .

Found a 7-pin model on eBay (22533568), wired it up on my 62’ K10 as described and I now have a nice chime for my headlight warning.
Thanks for all the help.

I need one of these also, Hoping there are a few 88-91 suburbans in the wrecker

[wilkin250r]

Honestly, probably the largest cost would be prototype boards for a circuit like that, adding a small microprocessor and a chime wouldn't significantly increase the cost. You can get a simple 14-pin AVR for like $2.00

GM integrated this function into the seatbelt warning buzzer along with the key in the ignition with driver door open buzzer.

The Headlamp warning option is RPO T63.

The "extra wire" in the RPO T63 equipped trucks is from the instrument panel lamps. I believe the ground is from the key inserted switch in the column.

Hello LDO,

Sent you a private message for a dummy buzzer!

Thanks,
Randy

I know this is a super old thread but I know you know wiring better than anyone else on here. Do you know what year c10s that this is a direct plug and play? I am guessing the 1981 and newer squares but it would be nice if it worked on some of the other ones. As usual, thanks for your knowledge in advance.

At least as far back as 1976 the seatbelt and key-in-ignition buzzer could be outfitted with the headlamp warning.
You'd have to add the wire from the parking lamp side of the headlamp switch to the buzzer jack IIRC.
