... only three types of bulbs, 3W, 1.5W and 1.2 W but multiples of each.
They don't know much more because this is what the computer shows them:
Item 3: 999.631.304.90 -- glass-base bulb 12V 3W Quantity X
Item 4: 999.631.303.90 -- glass-base bulb 12V 1.5W Quantity X
Item 5: 999.631.302.90 -- glass-base bulb 12V 1.2W Quantity X
Depending on the particular model year there will be different numbers of each in the cluster.
The larger green colored base is the 3.0W, the beige base is the 1.5W and the black base is the 1.2W
You really don't need to replace them all, because some of them will only come on when you turn on the ignition switch as a test.
The bulbs that should be preemptively replaced are the ones that get a lot of use and therefore are likely to burn out sooner:
Turn Signals and dependent on usage High Beam, Cruise Control, E-Brake, etc.
I'm sure you know, but here's a refresher course.
Once you remove the cluster to get access to its innards:
remove the clip from each end
Push open each one of the two connectors with a flat-blade screwdriver
then pry open the plastic tab
now you can open up the cluster
Here you can see where the turn signal bulbs are (only 2 of the green, 3W ones)
The white part is the front half of the cluster, looking at it's insides once it's been opened.
The black part is the rear half of the cluster.
This particular cluster, from 1999 has 11 of the 1.5W bulbs and 12 of the black 1.2W bulbs.
Hope this helps.
Happy Boxstering,
