YOU HAVE TO REMOVE THE COVERING FOR THE BACK OF THE MAIN COVER OF ALL LIGHTS. THIS IS INSIDE THE BOOT AND JUST LOOKS LIKE A CUT OUT,WITH THIS REMOVED YOU SHOULD SEE THE REAR OF THE LAMPHOLER AND A SMALL SPRING CLIP AT THE BOTTOM. THIS NEEDS TO BE PUSHED UPWARDS TO RELEASE,YOU THEN NEED TO PULL THE LIGHT COVER SLIGHTLY DOWN AND OUTWARDS FROM OUTSIDE THE CAR.
THE WHOLE UNIT WILL COME OUT AND YOU THEN NEED TO SQUEEZE THE TWO PLASTIC TABS TOGETHER TO REMOVE THE LAMP HOLDERS.
