ABSTRACT:
A retrofit optical assembly is provided for automotive headlamps that includes a multi-planar mirror that cooperates with a tapered end of a light guide to reduce glare. In an asymmetric parabolic reflective surface arrangement, the multi-planar mirror is offset from the longitudinal axis of the light guide to equalize the magnification and image size. This also has the beneficial effect of reducing the amount of light loss outside of the parabola.
