Abstract

A smart functional vehicle component includes a vehicle component, a leather sheet fixed over a surface of the vehicle component, a flexible electronic circuit contacting an A-surface of the leather sheet and including a printed and cured conductive ink, a light source that emits light when electrical power is supplied to the light source, the light source being electrically connected to the circuit, and a pigmented coating arranged over the electronic circuit and over the light source. The pigmented coating inhibits or prevents the circuit and the light source form being visible through the pigmented coating. Light emitted by the light source is visible through the pigmented coating. Light emitted by the light source provides visual indicators that convey information to a vehicle occupant.
