Beyond decoration: Interior lighting evolves into a key tool for safety, comfort and personalization in vehicles

Evolving from simple decorative features, ambient lighting systems now contribute to safety warnings, comfort-oriented functions and highly personalized in-cabin experiences across vehicle segments.

For several decades, vehicle interior lighting consisted mainly of a few lamps serving basic functions, such as assisting drivers and passengers when entering or exiting the vehicle or illuminating the cabin at night. Automakers primarily offered dome lamps and map lamps as standard equipment in all vehicles. Dome lamps, typically mounted in the center of the headliner, diffused light throughout the cabin, while map lamps, usually integrated into the front overhead console near the rearview mirror, provided focused, directional light for reading or searching for items in the front seats. In addition, some premium vehicles also featured rear reading lamps embedded in the headliner above the rear seats.
