You put your hand on the light and slide it forwards(or backwards cant remember which way) then pull out the back end of the light the whole holder comes out and you change the bulb and clip it back in. its a capless bulb the whole holder comes out do not seperate the lens from the holder. you could also open the inner wheel arch cover and change it in situ but if your not comfortable with doing that try the first scenario its simple enough.
