1157 bulbs have TWO elements and TWO contacts on the base, and the TWO pins are offset from each other.
Everything you have posted indicates/shows 1156 characteristics. If you don't believe me, go to your nearest auto parts store and try to buy a 1157 bulb with single element, single contact on the base, and directly opposed pins.
Why would you want a 1157 double element bulb in your vanity? Plan on hooking up your coach turn signals and letting the DW know ahead of time you are going to make a turn?
