A 2026 industry analysis by Depix describes how the exterior "face" of the car has become software: lighting is increasingly built from individually addressable pixels and OLED surfaces instead of fixed bulbs. FORVIA HELLA's RGB rear lamp renders 256 colors and plays welcome and goodbye animations, charging sequences and even a burglar-alarm light show, while Marelli showed OLED flat-lit surfaces at Auto China 2026 and Mercedes' Digital Light headlamps carry a million micro-mirrors each.

Because these light signatures are choreography rather than sculpture, their behavior can also be sold back to owners: Mercedes offers "Digital Light Animations" as a subscription garage light show, and Audi's Functions on Demand charges around $260 to unlock a headlight lighting package on cars already sold. RINA TECHNOLOGY's door welcome lights and dynamic grille lighting bring programmable approach-lighting effects to the global aftermarket.
