ok, so today i went to SAB to buy a front turn signal, which i know the bulb size is 1156. and i installed, and it doesn't fix, i go in try to return it and ask why it doesn't fix, and i ask some1 at the electric guy and they said my bulb size is 7507, they even said my bulb size is wrong that's why it doesn't fix, i spent 20 minute searching for the bulb size and can't find it. so pissed and the the bulb i brought and went home. any suggestion?
