A light assembly for motor vehicles includes a body made of a light-transmitting material. The light-transmitting material preferably includes a front light-emitting surface, and a plurality of rear surface portions that provide for inward reflection of light from a plurality of LEDs or other light sources. The reflective surface portions may be in the form of truncated parabolas having flat upper, lower, and/or side surfaces to reduce the overall height and/or width of the light assembly. The reflective surfaces can be oriented at off-axis relative to a vehicle axis to provide a specific beam intensity and direction.
