1. Open the Trunk: Obviously, start by opening your Buick Lucerne's trunk.
2. Locate the Lamp Assembly: The taillamp assembly is usually located on the inside of the trunk lid. Look for a plastic cover or access panel near the tail lamp itself. This panel might be held in place by clips, screws, or a combination of both.
3. Remove the Access Panel: Carefully remove the access panel. You might need a small flat-head screwdriver (or similar tool) to gently pry the panel free. Be gentle to avoid breaking any clips.
4. Disconnect the Bulb: Once the access panel is removed, you should see the bulb socket. There's usually a twist-and-pull mechanism. Twist the socket slightly, and then gently pull it out of its housing.
5. Replace the Bulb: Carefully remove the old bulb (it might be a simple push and pull or a twist). Make sure to match the new bulb to the old one's specifications (wattage and type). Insert the new bulb, making sure it's seated correctly.
6. Reconnect the Bulb: Push the socket back into its place and make sure it's secure. Twist it to lock if necessary.
7. Reinstall the Access Panel: Carefully put the access panel back in place. Ensure all the clips are securely fastened.
8. Test the Lights: Close the trunk and test the new bulb to make sure it's working correctly.
Important Considerations:
* Consult your Owner's Manual: The most reliable information will be in your Lucerne's owner's manual. It will have specific diagrams and instructions for your model year.
* Bulb Type: Note the bulb type before removing it to ensure you buy the correct replacement. You can usually find this information on the old bulb itself or in your owner's manual.
* Tools: You may only need your fingers, but a small flathead screwdriver might be helpful for prying open access panels.
If you're unsure about any step, it's always best to consult a qualified mechanic to avoid damaging your vehicle.
