For the 2012 Toyota Prius, headlight fitment depends on the factory headlight type. Models with halogen headlights use an H11 low-beam bulb, while models with LED headlights use an integrated LED low-beam system. The high-beam bulb is 9005, and the daytime running light also uses 9005.
Other notable exterior fitments include 7440A bulbs for the front and rear turn signals, plus a 7440 reverse-light bulb. The brake lights, center stop light, tail lights, and rear side markers are LED.
- License plate, parking, and front side-marker locations may use either 2825 or 98.
- The dome light uses DE3175, while the trunk light uses DE3022.
- Interior and map lights may use 168 or 917.
- Vanity lights may use 194 or 7441.
Verify whether the Prius has halogen or LED headlights before ordering a low-beam replacement.
