  1. 1

    Turn off your the engine, engage its emergency break and remove the keys from the ignition. Make sure the headlamp switch is set to "OFF."

  2. 2

    Walk to the back of your Focus and open the luggage compartment. If you're driving a wagon, use a screwdriver to remove the fixings and trim lining the rear of the car.

  3. 3

    Unscrew the three wing nuts holding the taillamp assembly to the car's body. Pull the assembly away from the body until it comes free.

    Find the bulb socket holding the broken bulb. Once you've found it, twist it counterclockwise and remove it from the assembly.

  5. 5

    Pull the old bulb straight out of the socket and replace it with the new bulb.

  6. 6

    Place the bulb socket into the taillamp assembly and turn it clockwise to secure its position.

  7. 7

    Test the new signal light to make sure it works before screwing the assembly back into position and closing the trunk.
