How to Replace the Dome Light on a Mercedes S-Class

Model: Mercedes Classe S W221, MK 5 - Years 2005-2013
Part: Interior dome light bulb

How do you replace the bulbs in the dome lights located in the roof of the Mercedes? Let's see how to disassemble it. Remove the courtesy handle with a screwdriver. Use a screwdriver to pry between the dome light and the headliner panel (without breaking anything), pull the dome light out of the panel, and disconnect the power connector. Replace the damaged bulb with a new one (same size and voltage). Push the clear dome light back in with your hands until the tabs lock into the plastic. Reinstall the courtesy handle on the roof panel. Test the dome light for proper operation after installation.
