The cool thing about Brooking Industries' new Shadow rear lighting system for police utility vehicles is how it mounts. It sticks to the back glass of the tailgate with industrial double-sided tape. Because it's mounted externally and the lights don't have to shine through the tinted glass to be seen, the lights can be more easily seen by motorists and that enhances officer safety. Available for Chevy Tahoe and soon to be available for the Ford P.I. Utility.
