Here's a general guide. Always consult your owner's manual for the most accurate and vehicle-specific instructions:
1. Locate the License Plate Light Assembly: The assembly is located on the inside of the trunk lid, above the license plate.
2. Access the Bulb: This is the tricky part and differs slightly between model years. Look closely at the assembly. You'll likely find:
* Small access panel: Some models have a small removable panel, often held in place by clips or screws. Use a flathead screwdriver to carefully pry this open.
* Direct access: In other models, you might have direct access to the bulb socket.
3. Remove the Old Bulb: Once you have access to the bulb socket, carefully twist the bulb counterclockwise to remove it. Be gentle; the socket is fragile.
4. Install the New Bulb: Insert the new bulb (make sure it's the correct type – check your owner's manual), and twist it clockwise to secure it.
5. Reassemble: Replace the access panel (if applicable) and ensure it's securely closed.
Important Considerations:
* Bulb Type: Use the correct bulb type. Your owner's manual will specify the correct wattage and type. Auto parts stores will have these readily available.
* Gloves: It's a good idea to wear gloves to avoid getting grease or dirt on the new bulb.
* Careful Handling: Be careful not to drop the bulb or damage the socket.
* Test: After reassembly, test the new bulb to ensure it works.
