But isn't the one that's also called the BAU15S the 7507? BA15S = (1156) vs BAU15S = (7507 PY21W) baseMy '93 TT won't fit a regular 1156 (BA15S) bulb. It needs the offset 150 degree pin configuration of the 7507 (BAU15S) base. My brother's '93 n/a Vert uses the standard 1156 (180 degree offset pin configuration bulb base). Still trying to figure out what gives with our cars having this slightly different bulb socket (and why).
