I need to change one of my corner bulbs, not sure which one? turn signals light it up, but the driver side orange bulb on the corner doesn't work when the headlights are on and I cant figure out how to get to it. one "how to" says to undo 3 screws and pull the headlight out. another says to take off the front bumper to get it out! help! dont wanna take the bumper off If i dont need to!
