For the 2015 Toyota Camry, headlight bulb fitment depends on the factory headlight type. Models with halogen headlights use an H11 bulb for the low beam and 9005 for the high beam. Models with LED headlights use LED assemblies for both the low- and high-beam functions rather than these replaceable halogen bulb sizes. The same distinction applies to the daytime running lights: 9005 with halogen headlights and LED with LED headlights.
Front turn signals and parking lights use 7444NA on halogen-equipped models, while LED-equipped models use LED lighting. Other listed exterior bulbs include 921 reverse lights, 7443R brake and tail lights, 7440A rear turn signals, 168NA front side markers, and 7443A rear side markers. The center stop light is LED. Interior fitment includes a DE3175 dome light, 168 or 917 bulbs for map and interior lights, and 194 or 7441 bulbs for the trunk and vanity lights. License plate lighting may use 168 or 917 bulbs.
