The SmartTap™ is a replacement turn signal flasher module compatible with any vehicle using a CF18 (LM449) Flasher. 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.

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!

    Great Product

    It's a lot of money for something that seems so basic, but it's worth every penny. Tap to turn is great, the hazards are great, and most important of all the arrival and departure lighting is fantastic, especially if you have switchback C-lights. Used in a 2015 Base WRX (Canadian model)

    Awesome product. The programs on the smart tap are convenient and adds a flavor to the rear lights. Eliminated the problem I had when I changed the tail lights. Love it so much I ordered another for my wife’s STI.
