Turning a Blank Panel Into Real Functionality

The C2R 4th Brake Light Kit replaces the blank trim panel found on many USDM Subaru rear bumpers with a genuine LED pod offering 3-in-1 functionality: a powerful reverse light, a 4th brake light with an optional F1-style flash pattern, and an additional red running light, all while maintaining an OEM appearance. The high-power red function activates anytime you apply the brakes, giving you a genuine 4th brake light where there was previously just an unused panel. The optional F1-style SafetyStrobe brake light flashes three times by default when the brakes are first applied, giving a distinctive look that can be disabled if you'd prefer a more traditional appearance. That's exactly the kind of thoughtful design Diode Dynamics built its reputation on.

A Genuinely Brighter Backup Light Too

Beyond the brake light functionality, the C2R is powered by automotive-grade high-intensity LEDs paired with custom-engineered TIR optics, delivering a dramatic increase in brightness when backing up at night compared to relying on factory reverse lights alone. The additional red running light adds a distinctive touch to the rear of the car while the vehicle is simply running, not just braking or reversing. It's a genuine functional and styling upgrade packed into a space that would otherwise just be blank plastic. For a component this critical, that level of engineering is worth having.
