Celica Forums General Discussion Exterior MTEC HELP

Just installed the MTECH lighting package and realized i need smaller lights to fin the spot in the side of the head lights. I saw in the store i need the m3's or the m7's, but i was wondering if anyone could tell me the difference between the two. (Besides the wattage). Are they made for different spots or just two choices?

u need the m4 for the parking lights...

those m7's are for the front turn signals and the m4 is the parking lights (the small lights on the side of the headlight). Im used to knowing them as 1156 and 194 bulbs
