Which bulbs are good for the GMT400 dashes?

If it were me I would use these. They throw light 360 degrees so minimal hotspots, and I doubt anything bigger would fit. Pretty sure I've seen people use these without issue.

Those are what I'm using in both my '91 and '98 dashes. I've tried several other options from SuperBright, but those are by far the best I've used.

6 for the primary gauge illumination.
