Part #: SMY - F1V3 - CLRD - GR. This rear brake light is a beauty! It has 8 red LEDs and a red trapezoid light bar that serves as the daytime running light. The 8 center LEDs can be either a hyper - flashing F1 - style brake light or a solid one, and you can switch between them easily from the driver's seat. There are 2 modes: Mode 1 offers a hyper flash with 15 blinks, and Mode 2 is a steady light with no flashing. You can switch modes using the brake pedal and headlight switch. Key features include the F1 hyper - flashing 8 - LED center, a DRL function where the white light bar turns red when marker lights are on, easy mode switching from the driver's seat (a market first), a wire loom, and high - end plugs for hassle - free installation. It comes with a rear brake light, mounting hardware, and instructions. For 2011 - 2014 WRX and STI sedans, connect the brake wire (red with white stripe in the car's tail light harness) to the blue wire from the RBL, the neutral wire (black in the car's tail light harness) to the black wire from the RBL, and the DRL wire (black with white stripe in the car's tail light harness) to the red wire from the RBL. It's suitable for 2011 - 2014 WRX and STI sedans.

Using your new rear brake light is easy. First, install it following the included instructions. Connect the wires as specified for your 2011 - 2014 WRX or STI sedan. Once installed, you can switch between the two modes from the driver's seat. To change modes, use the brake pedal and headlight switch. When you press the brake pedal, the center 8 LEDs will either hyper - flash 15 times (Mode 1) or stay steady (Mode 2). The daytime running light (DRL) function will make the red light bar light up when you turn on your marker lights. As for maintenance, keep the light clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals as they may damage the light. If you have any issues, refer to the instructions or contact customer support.
