I just picked up a '92 Z28 with Ttops. While replacing the dash speakers I noticed what looks like an empty light bulb socket in the center of the underside of the dash pad and directly above the heater controls. After removing the dash pad, I fished around in the dash for a light bulb pig-tail but did not find one. Is this a courtesy light bulb of some sort? I find it odd to have a hole in the dash but no bulb/pigtail present.

 

From what I've read, this is the mystery light. Seems like most cars have the cut out for it, some cars have the light, some don't. IIRC, it's more of a straight wired light (not something usually found in the aisle at auto parts store) - but it' been a few years since I've looked at mine. They shine so dimly that there's not much use for it really - the thought is that it lit up the ashtray area and maybe the shifter area - but it never did a very good job since most folks don't ever even notice that it's there.

 

I do believe its the ashtray light mine has it but dosent work ,you cant get them from GM it is a one piece unit and as far as I know there is no bulb that could be replaced and the ones that I did find at the wreckers were either broken or didnt work

 

The bulbs are still available at your local parts. Its a very small bulb. I just replaced mine last week. Got the bulb from AutoZone. All it does is shoot a beam of light down towards the ash tray so you can see it at night.

 

Aldaran do you remeber what the bulb part number was from Autozone?

 

I'm kinda doing the same thing but not! I'm replacing the "mystery light" that my car has with a pair of cold cathode tubes that will go to music or stay on/come on with interior lights. ....cutting the bulb from the end of the pigtail, hooking up the 12 volt source from the light set I bought that was designed to plug into ciggarette lighter, but I disassembled it to two wires..... join them up with the pigtail, leave one cathode light <which are 6" each> affixed to the centre console, the other light is going under the vents in the centre of the dash. Dead light bulb solved/upgraded/gayed up to some.

You could merely put ANY 12V lightbulb on the end of the pigtail if you wanted. Just gotta figure out which is +/- !

 

I'll snap some pics of the ashtray light on mine tomorrow. My 86 did not have it, but my 89 does.

Will

 

if you got pictures it would be great it would have to be one of the smallest bulbs known to mankind,at GM dealership they told me its a one piece unit with wire tail attached with no serviceable bulb

 

Here's a pic of the bulb... You can have mine. I replaced it with this. I can give you step by step and photos if you want. Its simple











These can stay on or goto beat of music. They can not dim, however being that they are fluorescent. Doesnt bother me, looks great! Much brighter in person, taken with a cellphone

 

wow very different than mine ,mine is a one piece unit see pics and size compared to the dime

 

lol...good old GM. 17 different bulbs/configs, one car. As i said, use anything you want to, as long as its 12v and you're sure of polarities. F the GM parts unless you're going for Concours award winner stock!

 

It's a very serviceable bulb, we have them at our shop, I'll get some info tomorrow

 

Did you get a chance to get the part number for the bulb

 

forgot all about it, I'll check monday

 

The one that fits my 1988 Camaro is a 74. It is the same mini-bulb used in 4th Generation Camaros to light up the interior door handles at night. My 2000 Camaro has them.
