This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

Napa carries them.

Re: This Dummy Needs a Headlight Buzzer
 

Oem?

Re: This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

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:mm:

Thanks for the great help.

Re: This Dummy Needs a Headlight Buzzer
 

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! :metal:

Re: This Dummy Needs a Headlight Buzzer
 

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

Re: This Dummy Needs a Headlight Buzzer
 

LDO, that right there is an awesome tip! Nothing like being stuck with a dead battery at Wally World of all places. Not speaking of myself of course.... :mm:

Re: This Dummy Needs a Headlight Buzzer
 

I believe I will look into this as well for my 82. I get comfortable with my newer vehicles doing things for me that I am prone to leave the lights on as well . Good info LDO .

Re: This Dummy Needs a Headlight Buzzer
 

I used the wiring harness from a 1989 Suburban when I re-wired my truck. It has a buzzer that comes on when the key is off and the headlights are on. I will have to see if I can find a part number.

Re: This Dummy Needs a Headlight Buzzer
 

Sorry for hijacking your thread Gass but it was such a coincidence that I was working on this myself and none of the older threads really helped much so I couldn't resist.

It seems alot of the earlier 80s trucks could have been wired for it but you will have to check. When you remove the module, you can tell if you have a 'female' receptacle for that 7th pin and that will tell you if you are wired. For my 85 Silverado, it was. I suppose it wouldn't take too much to wire it and make it look stock if you had a wiring diagram.

Best of luck to all. I'm hitting the junkyard this weekend and will try to scoop up as many of these units as I can and plan to send some out. When I was younger, I would prolly have pulled these out and trashed them, now that I am older (wiser?) I want the buzzer! LOL

Re: This Dummy Needs a Headlight Buzzer
 

Sweet, I just checked and while I have the 6 pin module, I can see that there are 7 pins wired in the receptacle. I know what's on my "to do" list!

Just for reference, it's an '87 Silverado.

Hey, I just thought of something. I brought home a 1990 S10 the other day so I can make a bed for my grandson using the bed from the truck. I'm even going to slice the last few inches off the cab and use it for the headboard. Anyway, I wonder if it has a 7 pin buzzer in it that would fit my Silverado? I'll find out today when I get home!

Re: This Dummy Needs a Headlight Buzzer
 

Cool,
it might! If not, I have a feeling I will have a few after Saturday. ;)

Re: This Dummy Needs a Headlight Buzzer
 

You did good Robert!! I just might have to look into this myself, I'll hit you up, when I need one!!

Re: This Dummy Needs a Headlight Buzzer
 

Yeah, we were just talking about it the other day so I figured I would dig deeper. :lol:

Re: This Dummy Needs a Headlight Buzzer
 

Re: This Dummy Needs a Headlight Buzzer
 

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?

Re: This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

I'll second that!

Re: This Dummy Needs a Headlight Buzzer
 

So I take my son to the junkyard and show him what we are after today and what possible year trucks would have it. Explain to him how to remove it and hand him a common screw driver. 10 minutes later, this happens. The kid was running around the yard like he was on an Easter egg hunt!:lol:

Here is the pic of our stash.:lol:

LINKY FOR ONE

Re: This Dummy Needs a Headlight Buzzer
 

I use a relay in the two power feeds, switched with an orange, ignition hot wire, or tap into a free spot in the fuse box.
If you look up how, it's not bad getting the wire out of the light switch plug, and then get another light switch harness to get a length of each wire to run from the relay to your OEM plug, it is reversible. If you ever need your lights with your engine off, turn your key to acc.

Re: This Dummy Needs a Headlight Buzzer
 

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

Re: This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

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

Re: This Dummy Needs a Headlight Buzzer
 

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

Re: This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

Hello LDO,

Sent you a private message for a dummy buzzer!

Thanks,
Randy

Re: This Dummy Needs a Headlight Buzzer
 

I took this route, about 5 minutes start to finish.

Re: This Dummy Needs a Headlight Buzzer
 

Details please.

Re: This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

cool, where did you get those, gm dealer?I got the one from napa, looks different...

Re: This Dummy Needs a Headlight Buzzer
 

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

Re: This Dummy Needs a Headlight Buzzer
 

Ok, hats off to LDO ! He sent me one of the units he gathered from the junk yard. I plugged it in and voila! The sweet sound of a headlight chime was mine. Yes, the same sweet sound that irritated us in our youth and caused so many of these units to be ripped out long ago. Thanks again LDO.

Re: This Dummy Needs a Headlight Buzzer
 

No problem. Glad I could help out.

Re: This Dummy Needs a Headlight Buzzer
 

Thanks again to LDO for the tip about the 7-prong buzzers. Got one at the junkyard this weekend for our ‘84 and it now has the headlight buzzer. No more neighbors stopping to tell us the headlights are still on! :lol:

Re: This Dummy Needs a Headlight Buzzer
 

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.

Re: This Dummy Needs a Headlight Buzzer
 

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.
