Abstract (en)
The part (4) has a zone (8) with variable light transmission coefficient, where the part is arranged to be visible from an outer side of a lighting and/or signaling device i.e. retractable headlight (1), when the part is assembled on the device. The zone partially covers an inner face (12) and an outer face (13) to define another zone (9) that is different from the former zone, where the latter zone has constant light transmission coefficient. Variability of transmission coefficient of the former zone is determined by an electrochromic device (11) that is fixed on the inner face. The part is made of a transparent or translucent element such as glass.
