2 ways to do it with the housing IN the car or take the housing out.....I do it with mine in but thats me look behind the headlight there is a black grommet inside there is a black "plug" squeeze the two sides and pull itll come unplugged ok once that is outI just take the black grommet off just pull it off there is a clasp holding the bulb in undo that clasp pull out the bulb, put in new bulb redo clasp put black grommet back on(there is an arrow that shows you UP so put that side UP) plug in the wire housing and tada! turn signals are easier just reach in there and twist the whole housing and take out the bulb put in new bulb twist the housing back into the headlight and tada
