Okay, thanks. It turns out that those are turn-signal bulbs, not wedge-base marker lamps (e.g. like #194), what you'd use in the side-marker lens.
You can find a really comprehensive listing of bulbs at http://www.4apc.net/parts_html/light_bulbs.htm
but I couldn't turn up a mirror-finished 194 bulb there.
I can't believe they don't exist _somewhere_...
Remember that LED versions won't work in this application because the current needs to flow _either_ way through the bulb in a GM front side marker so that it can work in conjunction with the turn signals. You _can_ use LEDs in repeater lamps, those little fender-mount lights that blink only with turn signals, since current only ever goes through them one way.
