The Diode Dynamics Stage 1 kit for Subaru Legacy (2015–2019) converts incandescent tail lights to operate as turn signals while upgrading to LED for a modern look. Using OEM connectors, the plug-and-play installation requires minimal effort and the kit can also repurpose the old turn-signal socket as an additional backup light where applicable, increasing reversing visibility with vehicle-specific hardware included.
