For the 2018 Subaru Crosstrek, headlight bulb fitment depends on the factory headlight setup. Low-beam lighting uses an LED unit or an H11 bulb, while high-beam lighting uses an LED unit or a 9005 bulb. Confirm whether the vehicle has halogen or LED headlights before ordering replacement bulbs.
Daytime running light fitment follows the same distinction: halogen-headlight models use 9005 bulbs, while models with LED headlights use LED lighting. Fog lights are listed with H11 LED or H16 LED fitment.
Other useful replacement details include 7444NA front turn signals, 7440A rear turn signals, and 7440 reverse lights. Brake lights and the center stop light are LED. Tail lights and license plate lights may use 168 or 917 bulbs, while front and rear side markers use 168NA bulbs. Interior fitment includes DE3175 bulbs for the dome and map lights, and a DE3022 bulb for the trunk light.
