1157 and 1156 have different sockets, and are totally different. The 1157 has 2 filaments, while the 1156 has one filament. Yes you could shave off the knobs at the sides to make a 1157 fit a 1156 socket (and vice versa) but I'm not sure how good it will work... for corners, I know on JDM 5gen, they come with 1156 harnesses as opposed to USDM 1157 harnesses. If you look at your manual, or your original bulbs that came with the car, they aren't 1157/1156, they have different numbers: **57, like 4057 but 1157 should work. There are some german bulbs that look like they fit, but the pegs on the side won't let you.
