## Abstract

A vehicle lighting system includes first and second lighting devices. The first lighting device has a first opening, and the second lighting device has a second opening. The first opening provides access to a first installation space on the first lighting device, and the second opening provides access to a second installation space on the second lighting device. The first and second installation spaces are essentially mirror images of one another. A first fan unit is located at the first opening and a second fan unit is located at the second opening. The first and second fan units are essentially mirror images of one another.

## Claims
