hey guys, im looking for the turnsignal bulbs on the front of my car. mine got messed up so im lookin for a replacement bulb. do u guys know what part # it is and where i can get it? im thinkin radioshack? or will i have to go to a dealer. sorry if i sound really noob. but i already searched and havent found anything.
btw, is it normal for my clicker to click fast all of a sudden. ever since the bulb for my right turnsignal got messed, my car blinks crazy fast on the right but all normal on the left.
