A simple explanation can be found in the owner's manual, but assuming you don't have it (like me jeje). Here is what you do
1) Disconnect the bulb from the wiring (there is a little latch you can press and then pull backwards away from light bulb). 2) Twist the safety covering until it comes loose. 3) Pull back both the bulb and the safety covering. 4) Now you'll have the bulb and safety separated from everything, simply replace the bulb (9007 series) and do the backwards process to reinsert the bulb and reattach it to the wiring, and all done.
Try not to touch the bulb with your fingers, the oils on your hands will make the bulb burn out faster. use clean rubber gloves or tissue paper to hold bulb.
