Hey everyone So my blubs in my climate control burnt out. I know they make blubs can swap out. I'm not sure what sizes i need i know there is a long blub and the short one. Looking for options for led to brighten it up a bit. I can't figure it out I'm sure others have upgraded. Thank you for all the help.

The one on the left i think is a pc74 not sure hard to find and wanted to change that to a LED. The one on the right has wires coming from it. so can't really find any info on that. They are not 194. Thank you.

the photo gives no sense of scale. Usually the part number is printed right on the bulb.
No idea if I'm looking at a 1" or 1/4" bulb


Is it this one I get when I search for "chevy instrument panel bulb"?
