The head light bulb just rotates counter clockwise to disengage it from its lamp. If it is a low beam Xennon HID light there is usually a cover to be removed first and the lamps operate on high voltage and are more difficult to change. Autozone have some popular workshop manuals for free on line once you register (for free) on their website .There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. or try and get an online repair manual subscription.
