Using your SMY F1 V2 Hyperflash Rear Brake Light is a breeze. First, follow the installation instructions that come with the package. You'll need to connect the wires as specified for your 2011 - 2014 Subaru WRX or STI sedan. Once installed, you can easily switch between the two modes from your driver's seat.
