Raxiom 05-09 Ford Mustang Sequential Tail Light Kit (Plug-and-Play)Finish off the classic retro styling of your S197 Mustang with a set of Raxiom sequential taillights. Sequential taillights were used on the Shelby Mustangs from 1968 to 1970 and now you can have them for your modern pony from Raxiom. When activated, the turn signals or hazard lights will sequence from the center light out and repeat until switched off. When the brakes are applied, the tail lights will sequence once and then stay lit during braking.
