For models with later models you pop the bonnet, then turn the cover on the back of the headlight a quarter-turn anti-clockwise. Put on gloves, then pull the headlight and wiring out. Use a flat-head screwdriver to remove the H7 globe from the plug and mounting ring. Place mounting ring on new headlight bulb, push until it clicks, then refit. Older models are simpler. Pop the bonnet then pull the wiring plug away from the back of the headlight. Spin the cover anti-clockwise and then pull the H7 Halogen globe out with the cover. Do not touch the globe with your bare hands as it will shorten the lifespan of the new globe. Because of this, and the tight confines of the work space you should wear gloves when doing this job.
