Well, the bulbs are available only from specialty places like Eeuroparts and theSaabSite - They list bulbs for the SID and ACC
For the SID - TSS has the upper ones actually for the later ones which I think are the same as the upper ones in the 97 (
http://www.thesaabsite.com/93/93electrical.htm) - or eEuro has ones listed...(
http://www.eeuroparts.com/productdetail.aspx?searchResults=1&code=9838) which are a different wattage so they may be correct thought I would call Dale to be sure - as his listing is not specific - I just replaced mine a while ago - at the time he had to look them up as there was nothing in his catalog...he tends to add things after they are ordered.
Here is the fun part - they are like $10 each. They are different wattage - 1.1w I think and 1.8w so you cannot interchange the lower bulbs with the upper - one has a grey base and one white. The lower ones for the buttons are slightly more expensive and are grey based (and I am pretty sure they are the 1.1w listed at eEuro but again, I would call to be sure).
Now to replace them - pop out the sid per any of the instructions on this site (or on the TSS link above)...the bulbs are twist ins - so take a small screwdriver - turn the appropriate bulb base (grey plastic circle) - and remove the bulb - replace.
To replace the ACC bulbs - same thing - pop out the unit - and they are the same design bulbs
Sorry to ramble - it is Monday AM...If you need more info than that - let me know
