Autoloc's Self-Cancelling Turn Signal Module Kit is perfect for retrofitting your 1903 Cadillac Model A without self-canceling turn signals. The Self-Canceling Turn Signal Controller allows you to limit the pulse length of your turn signals with ease! With the Autoloc Controller Module you are able to adjust the flasher pulse rate (how fast the flasher blinks). Ideal for push button turn signals.

Turn signal will also automatically turn off when no longer needed. Designed with solid-state electrical components, this controller is meant to last. Detailed instructions and toll free US tech support makes installation a snap.
