Custom Dynamics Auto-Cancel Turn Signal Module for 1973-1991 Harley-Davidson Sportster FX FL
Older Harley-Davidson models and custom builds without self-cancelling turn signals get the convenience of automatic cancellation, plus 4-way hazard flashers, without replacing the switchgear or adding external controls. The hardwire connection integrates into the existing turn signal circuit, leaving the cockpit unchanged while modernizing one of the most-overlooked aspects of early motorcycle electrical systems.
