Provided is a vehicle lamp including: a light source; and a light guide extending in a predetermined extension direction and configured to guide therethrough a light from the light source such that the light is incident from a rear surface and emitted from a front surface. The light guide includes a guide element including a front incident surface formed in a portion of the rear surface facing the light source; a side incident surface formed on a side of the front incident surface on the rear surface, and a reflecting surface formed on a side of the side incident surface on the rear surface and configured to totally reflect the light incident from the side incident surface toward the front surface. A joint portion between the front incident surface and the side incident surface is formed as a curved surface.

Vehicle light assembly having a colored appearance in an unlit state

A vehicle light assembly is provided that exhibits a colored appearance when in an unlit state. The vehicle light assembly comprises: a housing; one or more light sources mounted in the housing; and a light guide configured to receive light from the one or more light sources and project the light outwardly from the light guide. The light guide includes a first segment proximate to the one or more light sources and a second segment distal from the one or more light source, such that the light from the one or more light sources passes through the first segment of the light guide before passing through the second segment of the light guide. Of note, the first segment is comprised of a colorless material; whereas, at least a portion of the second segment is comprised of a colored material.

OPTICAL ELEMENT AND CORRESPONDING VEHICLE LAMP AND VEHICLE
