Upgrade your Subaru with the SmartTap™, a plug-and-play replacement for your factory turn signal flasher relay—engineered to deliver much more than just blinking lights. Powered by an embedded microcontroller and custom software, the SmartTap™ adds advanced functionality and user-programmable features to take your lighting to the next level.

Features:

• Tap-to-Signal: Enjoy one-touch signaling for effortless lane changes. Simply tap the turn signal and your lights will blink automatically. The number of blinks is fully programmable—tailor it to your exact driving preference.
• Custom Hazard Modes: Stand out in emergency situations with eight unique hazard light patterns, including strobe, slow-motion (slo-mo), and wig-wag effects. Use them individually or in combination for maximum visibility and impact.
• Arrival & Departure Lighting: Improve nighttime safety and style. When locking or unlocking your Subaru, the SmartTap™ keeps your turn signals glowing for up to 90 seconds (programmable), helping illuminate your path as you enter or exit the vehicle.
• Easy Installation: No wiring or splicing—just plug it in. The SmartTap™ is designed specifically for the WRX / STI for true plug-and-play functionality.
