twist and pull

 

look outside your car where your headlights are. Look at where the bulbs are, now visualize the back end of them inside your engine bay. Then look at the wires connecting them. The wires attach to the mount that holds the bulbs. As Iam7head says, twist and pull.

If I were you i'd clean the area of dirt (brackets, wires, etc). And DONT TOUCH THE BULBS WITH YOUR HANDS. This way dirt doesnt get inside the housing, and especially not on the bulb, which can burst if there is oils or dirt on it.
