The facelift B5 light unit looks like the same unit thats used in the very first link in this thread (which i think is an A3?).
For confirmation, ETKA says the main bulbs are N0177234 "K-12v10W" and the reading lights are N90034901 "T4W-12v5w"
The rear light uses the same bulbs as the reading lights up front. The sunvisor lamps again look the same as the A3 in the first link N0177252
Boot on an avant uses N90841101 "12w6W" and the saloons use a pair of the aforementioned N0177252's
