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 Taillights by 200%. Drake's sequential light systems come complete with control modules, an electronic variable flasher and 2 dedicated three bulb inserts, ready to install in your taillight housings. All required electrical connectors are provided. We strongly recommend the use of Drake's special polycarbonate lenses with this kit. Detailed instructions included. Assembly required.
