I've seen people looking for those 6v bulbs and have resorted to paying $3 for a turn signal bulb and $4 for a taillight bulb... Well, go to your local autozone or advance auto etc and look for Sylvania 1129 for turn signal (single element) and Sylvania 1154 for tail lights (dual element). Get 2 bulbs for what your dealer will charge you for one of the same bulb.
I'm a wealth of useless knowledge and grand ideas... all ya gotta do is ask =P
