I can't seem to find 7440 in amber from any reputable brand (sylvania, GE, etc). Do any other single-filament sizes work w/ the 7440 socket and the bumper turn signals for a 5th gen accord?

Also, what are some bulbs that have the same base/fit as 168 (and besides 194)? I'm trying to find some brighter corner bulbs... so far 906/912/916/921 all fit in the inner parking light of the corner lamp, but are all too big to fit on in the spot for the turn signal corner (what i really need)... so are there any other sizes that fit the corner lamp that draw more than 5w?
