8. A seatbelt buckle for a vehicle, comprising:
-
a housing; a latch mechanism; a first light source disposed within the housing optically coupled to a first light guide that is configured to illuminate a first portion of the buckle; a pair of apertures proximate a tongue receiving slot, wherein the first light guide directs outputted light through the apertures to illuminate the tongue receiving slot; a diffuser disposed in the pair of apertures and proximate one end portion of the first light guide, wherein the diffuser is configured to direct light outward from the housing; a second light source disposed within the housing and optically coupled to a second light guide that is configured to illuminate a second portion of the buckle; and a luminescent structure configured to emit outputted light in response to excitation by inputted light emitted by the first light source. - View Dependent Claims (9, 10, 11)
