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 60's. The inserts alone increase the brightness of the tail lamps 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. We strongly recommend the use of our special polycarbonate lenses with this kit. Detailed instructions included. Assembly required.
