i just bought a 2006 Mazda 3 hatchback from a buddy. I went to change the bulbs today and found something strange. The bulb I pulled out of the car was a 9003 (3 prong connector). The bulb I’m being told goes in it is a H7 but that only has 2 connectors. The 9003 bulb does not fit in the socket correctly. My lights don’t shine out in front of me only towards the ground. I’m at a loss and looking for help. Any clue as to why the bulb suggested by the auto store doesn’t match the connector in the car?
