Abstract
A vehicle lighting system comprising a light source for generating light illumination, a liquid lens optically aligned with the light source to receive the light illumination and generate an output beam, and a controller configured to control electric power supplied to the liquid lens. The controller applies a first voltage to the liquid lens to generate a first output beam having a first beam size and generates a second voltage to the liquid lens to generate a second output beam having a wider second beam size.
