The Diode Dynamics' SmartTap™ is a replacement turn signal flasher module compatible with any vehicle using a CF18 (LM449) Flasher, including most Toyota Models. Programming each mode is simple with the help of the included programming guide and the use of existing vehicle controls.

Tap-to-Signal: One-touch signaling is a convenient way to signal to other drivers when switching lanes. Simply tap the turn signal for a series of signal blinks.

Arrival and Departure Modes: When the lock or unlock button is pressed, the surrounding area will illuminate for better visibility when approaching or leaving the vehicle at night. The lighting time can be adjusted from 10-90 seconds for additional illumination, or disabled if desired. *Not compatible for all vehicle models*

Unique Hazard Functions: The SmartTap™ has built-in strobe, slo-mo and wig-wag hazard functions to help the vehicle stand out when the hazards are on. Apply these functions on their own, together or with the strobe setting for a total of EIGHT unique hazard functions!



SmartTap™ was designed and fully manufactured by Diode Dynamics, in St. Louis, Missouri. It is fully made in USA.
