Three types of headlamp are available; Halogen, Bi-xenon or Adaptive Front lighting System (AFS). All headlamps share a common, clear lens.

The headlamps are located on the bonnet locking platform. Each headlamp is secured at the top to the bonnet locking platform with two screws and at the bottom to the front bumper support bracket with one screw. Headlamp removal is facilitated by removal of the radiator grille and removal of the three headlamp attachment screws.

Headlamp removal is required for replacement of any of the bulbs. The rear of the headlamp unit has removable access covers which allow access to the bulbs.

A large cover, which is rotated counter-clockwise to remove, allows access to the low/high beam bulb on both halogen and xenon headlamps.

A second cover, on the inboard side of the headlamp, can be removed to allow access to the high beam 'fill-in' lamp halogen bulb. The bulb is mounted in a holder with an extended end to aid removal.

A third cover, located on the outboard side of the headlamp, can be removed to give access to the side marker lamp bulb (NAS only), the side lamp bulb and the cornering/static bending lamp bulb (if fitted).

The turn signal indicator bulb is located on the outboard side of the headlamp. The bulb is a push fit into a holder which is secured in the headlamp body by rotating clockwise.

In all markets except NAS, the headlamps have two adjustment screws which allow for the manual setting of the vertical and horizontal beam alignment. A 6 mm Allen key is used to rotate the adjusters to achieve the required setting. The inboard adjuster controls the vertical aiming and the outboard adjuster controls the horizontal aiming.

On NAS vehicles the headlamp is regarded as 'Visual Optically Left' (VOL) aiming. The adjustment screws have to be turned equal amounts to maintain the correlation in the vertical axis only. There is no horizontal adjustment.

Each headlamp has an integral sixteen pin connector which provides inputs and outputs for the various functions of the headlamp assembly. The usage of the pins differs between model variants.

Three breathers are located on the rear of the headlamp housing. The two lower breathers are fitted with 'C' shaped tubes and the upper breather has a 'T' shaped tube. The breather tubes which allow air flow in and out of the headlamp but prevent the ingress of moisture from rain, road spray or washing. If condensation occurs within the headlamp, check that the breather tubes are not blocked with mud etc before further action is taken.
