ok im confused i just took out my guage cluster, too see if i could replace some bulbs to make my culster light up blue at night instead of the stock dull greenish color. (figured i would just replace some bulbs with blue ones). now i am REALLY confused the stock bulbs already have a little blue rubber thing over them,so it should already light up blue but its the normal dull greenish color. um...im confused what do i do to make it light up blue?
