Another new and unique product from Scott Drake. Scott's goal was to provide the classic Mustang with sequential turn signals like the T-birds and Shelby's of the '60s. The inserts alone increase the brightness of the taillamps by 200%. Our sequential light systems come complete with control modules, an electronic variable flasher, and 2 dedicated three bulb inserts, ready to install in your taillamp housings. All required electrical connectors are provided. This deluxe kit comes with special polycarbonate lenses. We installed the three bulb inserts into our taillamp housings to make installation just that much easier. Detailed instructions included. Assembly required.
