The 2022 Toyota Prius uses integrated LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not list a replaceable halogen-style bulb number for either beam, and no projector or non-projector headlight variation is specified.
Front fog lights, daytime running lights, front turn signals, brake lights, the center stop light, tail lights, and license plate lights are also LED. The front and rear side markers and parking lights use 2825 bulbs. For rear signaling, the turn signal uses a 7440 bulb.
Inside the Prius, the dome light uses a DE3175 bulb, while the map, trunk, and vanity lights use 168 bulbs. Reverse-light fitment is not listed in the supplied data, so confirm the original bulb before ordering.
