IIRC, 194 or 168 bulbs fit nicely in the twist-lock doohickies. It's been a standard dash bulb for many years now.
I dunno why, but I've only had one headlight, 2 clearance lights, a couple HMCSL blubs and I think one dash light burn out in the 12 years I've had my '98. Oh, yeah. The rear tag bulbs have burned out a time or two, and the fixtures have failed, to.
