after unscrewing the black cover thing there should be a wire clip that u can unhook and once u do that the bulb should be out.
its a bit tricky if your car is lowered or if u have the front spoiler coz u can't really poke your head under there to have a good look. best way is to jack it up a little or park on a slope or something as taking it out is ez, putting it back is the real b*tch
