A chrome-housed center high-mount third brake light with white and red LEDs that replaces the factory unit above the rear window.
why this one — At around a hundred dollars this is by far the cheapest way to modernize the back of a GMT900-era Sierra HD, and ANZO own fitment list names Sierra 1500, 2500HD and 3500HD on the one part number. Honest downside: it is a single small lamp, so it does nothing for your main taillights and will look mismatched next to faded factory units.
