This Diode Dynamics tail-as-turn plus backup module kit converts Subaru WRX/STi tail lights to act as turn signals for 2015–2021 models, using OEM tail light connectors for plug-and-play installation. The Stage 2 option includes bulbs to repurpose the old turn-signal socket as an additional backup light, increasing rear visibility when reversing while delivering a cleaner, more modern rear-light appearance without complex wiring.
