The taillights on first-generation Mustangs were notably dim. The lights and their wiring are also prone to rust and fraying over the years. If your 1966 Mustang’s taillights could use a refresh or an upgrade, we’ve got what you need. Pick up a new taillight body, bezel, lens, or full assembly to restore your lights to their original glory. If you just need to replace some hardware, gaskets, and bulbs, we have those as well.
