摘要:
A pointer for an instrument cluster assembly of a motor vehicle is provided. The pointer includes a pointer arm and a light distributor formed of light conducting material. The pointer arm has a proximal end and a distal end. The light distributor is disposed at the proximal end. The light distributor has a light receiving side and a light reflecting surface. The light distributor is configured to receive rays through the light receiving side. The light reflecting surface is configured to reflect rays into the pointer arm. The light receiving side has an inner portion and an outer portion. The inner portion is disposed closer to the distal end of the pointer arm than the outer portion is with respect to the distal end. Angled surfaces are disposed on the inner portion. The angled surfaces are configured to refract rays toward the light reflecting surface.
