Jaguar has taken the decision to remove front fog lights from all there new products (hence both the XF and revised XK do not have them). As some have mentioned, one of the reasons for this is that cars fitted with xenon headlights do not require additional light from another source. However the misuse of fog lights by some drivers, which can lead to dazzling of other road users, is another reason. The major cause of accidents in the fog is cars failing to break in time and rear-ending the car in front, that's why rear fog lights are so important.
