For the 2013 Subaru Impreza, the high-beam headlight uses a 9005 bulb. Low-beam fitment depends on the headlight configuration: base models with halogen headlights use H11, while base models with HID headlights use D2R. The WRX STI Limited uses a D2S low-beam bulb, so confirm the headlight type and trim before ordering.
Other fitment varies by body style and equipment. Front turn signals use 7440A, while the WRX Limited uses 1157A. Rear turn signals use 7440A. Reverse lights use 921, with 7440 listed for the wagon. Rear brake and tail-light fitment may be LED or, on sedans with halogen headlights, 7443R.
