If this is the bulb you bought, it's the wrong one. You need 2 contacts on the bottom, and the pins on the sides of the socket need to be even. The bulb you bought shows the pins to be off-set. The package you show says it is 1156 compatible but that makes no sense.....It looks like it would be 1157 compatible (2 filament, off set tabs used in brake/taillight systems).
