SubiSpeed USDM TR Style Sequential Tail Lights - Subaru WRX / STI 2015+
NOTE: These are compatible with Diode's tail as turn harness. Instead of having an amber turn signal, you would use the inner red LEDs as a brake / turn signal.
NOTE: These are now Plug & Play. They also ship with load resistors to prevent hyperblinking. These units are outside of the casing to aide in preventing condensation build up.
