How do you replace a bulb in the headlight mount of a 94' Toyota Corolla?

Just did this today. First you have to remove the plastic air vent thing above the headlight(drivers side)-its atached to the metal frame. When removed you reach down to the back of the head light and unscrew and pull out the socket. Remove and replace the bulb then return the socket to the head light and screw it back in place. Its tricky due to the awkward position of your hands. Dont forget to replace the air vent thing. (sorry for the non-tech nature of the terminology)
