Car owners who are not mechanics might be able to replace dashboard lights in a Mercedes or other vehicle if they can find out how to remove the trim panel and the instrument cluster. An amateur can find tips on removing the trim panel from the car's manual.
The person performing repair work might need to remove the radio before removing the trim panel. The trim panel likely has some screws holding it in place, and removing these screws lets the panel tilt forward, allowing access to the electrical connections. Replacing the bulbs is generally simple. After unscrewing the old bulbs, the new ones should be easy to screw into place.
