Tools You'll Likely Need:
* Phillips head screwdriver (likely a #2)
* Possibly a trim tool (plastic pry tool to avoid scratching)
* New tail/brake light bulbs (ensure you get the correct wattage and type; check your owner's manual)
Procedure:
1. Open the rear tailgate: Fully open the rear tailgate of your station wagon.
2. Locate the light assemblies: The taillights are integrated into the tailgate itself. You'll see the lenses on either side.
3. Remove the inner trim panel (if necessary): Some models might have a small access panel or inner trim panel covering the light bulb sockets. If present, gently pry this off using a trim tool. Start at one corner and work your way around. Be careful not to break the clips.
4. Access the bulb sockets: Once the inner trim is removed (if applicable), you should be able to see the light bulb sockets behind the lenses.
5. Remove the old bulb(s): Gently twist the old bulb(s) counterclockwise to remove them from their sockets. They might be a bit snug. Be careful not to break the filaments or damage the socket.
6. Install the new bulb(s): Insert the new bulbs into the sockets and gently twist them clockwise until they are securely fastened. Ensure they are seated correctly.
7. Reassemble: If you removed an inner trim panel, carefully snap it back into place.
8. Test the lights: Close the tailgate and test the lights to ensure they are working correctly (brake lights, turn signals, reverse lights, and tail lights).
Important Considerations:
* Bulb types: The 2003 Ford Focus uses specific types of bulbs. Check your owner's manual or the bulb itself for the correct replacement. Getting the wrong bulb can lead to issues.
* Safety: Always turn off the ignition and disconnect the negative battery terminal before working on the lights to prevent accidental shocks.
* Grounding: If the new lights don't work, ensure the bulb is properly seated and that there's a good ground connection.
If you're uncomfortable with this process, it's best to take your vehicle to a qualified mechanic. They have the tools and experience to do the job safely and efficiently. Incorrectly installing the bulbs could lead to further electrical issues.
