We're going to replace the original turn signal switch in Carol Marini's '68 Mustang hardtop, which has been driven more than 800,000 miles in 45 years.

The turn signal switch on 1994-2004 Mustangs does more than just operate the turn signals on your Mustang. It also controls the windshield wipers and houses the hazard flasher switch.

In this case, that was accomplished by installing a set of Juliano's new teardrop external-mount lights, which are complete with running light/turn signal wiring pigtail and LED bulbs.
