2013-2015 Subaru Crosstrek XV 4th Brake Light Kit

The Diode Dynamics C2R 4th Brake Light Kit is a direct-fit LED lighting upgrade for the Subaru Crosstrek that adds a dedicated fourth brake light to your rear end for improved visibility and following-distance awareness. Mounted in the rear window area using a vehicle-specific bracket, it integrates cleanly without cutting or splicing, giving you a finished, factory-look result.

Beyond braking, this kit pulls triple duty — it also functions as a high-output reverse light and an always-on running light, so you're covered day and night. An optional F1-style sequential flash pattern gives you an extra attention-grabbing signal when braking hard, which is especially useful in slow city traffic or on busy highways.

Custom-engineered TIR optics inside each pod focus the output where it matters, delivering crisp, bright light rather than washed-out glow. If you want a practical safety upgrade that genuinely improves how visible your Crosstrek is to drivers behind you, this kit is a straightforward choice.
