The turn-signal bulbs on a 2003 Jaguar S-Type are located in the outer-headlamp case. The bulbs can be accessed and replaced without removing the headlamp case, which makes the process simpler than in some other vehicles. There is no specific replacement schedule for these turn-signal bulbs. Instead, they should be replaced as they burn out. It's a good idea to keep replacement bulbs in your glove compartment in case one burns out at an inconvenient time.

  1. 1

    Open the bonnet. Locate the four fasteners on the plastic shroud at the front of the engine compartment. Twist the fasteners by hand, counterclockwise. The fasteners do not come all the way out.

  2. 2

    Lift the plastic shroud and set it down for safekeeping. This provides you with access the headlamp cases. The turn-signal bulbs are located within the outer case on either side, directly above the circular headlight-bulb cover.

  3. 3

    Reach behind the headlamp case. You'll be able to see the turn-signal bulb by looking at the rear of the case. Turn the socket counterclockwise to detach it. Pull it straight out.

  4. 4

    Gently pull the bulb from the socket. Insert the new bulb into the socket. Make sure you wear gloves, or wrap the new bulb with a paper towel. Touching the glass causes damage to the bulb.

  5. 5

    Insert the socket into place. Line up the small notches on the socket with the notches on the case. The socket only inserts one way. Turn the socket clockwise.

  6. 6

    Place the plastic shroud back in place. Turn the four fasteners to secure the shroud.
