I do have an Autozone, but I'm looking into that bulb recommended by the link at that other forum "scoobymods". He recommends a slightly yellow tinted part "Narva All Weather".
As I do a lot of fog driving I like the idea of a slightly yellowier light. I'm sure you want to be as far from yellow as possible.
Anyway I send off an email to this Dan guy that is linked in the forum to inquire.....
