For the 2019 Subaru WRX, headlight bulb fitment depends on the factory headlight configuration. High beams use either a 9005 bulb or an integrated LED setup. Low beams are LED on vehicles equipped with LED headlights; models with halogen headlights use an H11 low-beam bulb.
Fog-light fitment also varies. The supplied options include H11 LED and H16 LED replacements, while WRXs with LED headlights use LED fog lighting. Confirm the original housing and connector before ordering.
