For the 2004 Toyota Prius, headlight bulb fitment depends on the headlight type. Models with halogen headlights use a 9003 bulb for both low beam and high beam. Models equipped with HID headlights use a D2R bulb for both functions. Confirm the headlight configuration before ordering, since 9003 and D2R bulbs are not interchangeable.
Other notable fitments include an amber 7440A bulb for both the front and rear turn signals, and a 7440 bulb for the reverse lights. The brake lights and center stop light are listed as LED. Parking lights, front side markers, and tail lights use either 2825 or 98, depending on the installed configuration.
