Well i think its standard so you jus take the cover off take the plug off unclip the clip (try not to take it off completely as its a nightmare to get back on) slide the bulb out do the opposite to put new one in but please take care insuring you do not touch the glass of the new bulb as the moisture from your hands will cause the bulb to blow when switched on. Hope this helps
