Abstract
A molded component assembly includes a printed circuit board with a first face and an oppositely facing second face. Multiple light emitting diodes are mounted on a first portion of the first face. Multiple electronics components are mounted on a second portion of the first face. A light guide of a light translucent polymeric material is positioned over the light emitting diodes and the electronic components. The light guide includes: a contact surface directly contacting the first portion of the first face except at locations of the light emitting diodes; a cavity created in the contact surface, the electronics components located within the cavity when the contact surface directly contacts the first portion of the first face; and a through hole extending through a body of the light guide and opening into the cavity.
