If you just have a broken lense,you can pop off the old unit with a largish screw driver.
open the bonnet,un plug the light...the lamp is clipped on in 4 places,put your screw driver behind the bowl part of the lamp and prize forwards not too hard tho and the light should pop off,then the new one,offer it up to the mounting with the 4 balls on then just give it a tap with your hand not too hard so ya dont break it....plug it in...job done !!
