Diode Dynamics C2R 4th brake light kit for 2015–2021 Subaru WRX replaces the blank rear bumper trim panel with a compact LED pod delivering three functions: a high-power reverse light, a high-power red 4th brake light with an optional F1-style flash pattern, and a red running light. It uses custom TIR optics, an OE-style bracket for a flush fit, and a plug-and-play wiring harness for straightforward installation.
