These headlamp units are standard-issue on 2015-2017 WRX Limited models and all 2015-2017 STI models.  They have an LED projector low beam and a halogen reflector high beam, plus an LED-illuminated "boomerang" accent lamp.  These WRX/STI headlights bolt directly into any 2015-2017 WRX, with no additional wiring required.  Note that these lamps have height adjustment motors, but cars not factory-equipped with the lamps will not have the sensors or wiring for automatic adjustment.  You can still adjust them manually.

Set of two lamps, left and right.

Fits all 2015-2017 WRX and STI.
