Cluster illumination uses #194 bulbs, but the little funky looking ones are actually LED's, that's why they're soldered to the PC board. They are serviceable individually, Radio Shack should have them.... cheap.

Well it is 2014 and a add on to this thread. I did the junk yard swap. Found out when I took the original out and plugged it back in the Light worked. Then when I sarted the engine the Service light would not reapear when working the key thru the positions. I put the junk yard one one Hey the light is on until I fully turned key to run. Damn put original back on. Now what to look for 02, ECM? Disconect battery and resart ECM? And for anyone asking You can't use a "Non-Tach" in a "Tach" and visavers. It leaves out Selector positions and odometer. Mine also left off gas gauge.
