Hi i was wondering what the names of the bulbs are which i need to fit on my astra MK4. i want to change my botton fog lights and my headlights. I am aware that the headlights are called H7, but what are the foglights called? by fog lights i mean the lights underneath the headlights. Are they 9005 bulbs i need or H3's? because i have read two different topics which say they are H3's and one topic ses the bulbs i need for my foggies are 9005's!
