how to change headlight bulb for ford mondeo 2002?

Hi,
Can anyone help, how to change headlight bulb for ford mondeo 2002.
Also half of spedo meter lights (left side/heat gage) goes off again and again... is there any problem with fuse or something else???
this time main headlight bulb gone at passanger side (left side ofcourse), is it related to fuse problem as well (just a thought).
any help would be great. Thanks in advance
