For the 2016 Toyota Avalon, headlight bulb fitment depends on the factory headlight system. Avalons with halogen headlights use a 9005 bulb for both the low beam and high beam. Models with HID headlights use D4S for the low beam; the supplied fitment data does not list a separate HID high-beam bulb. Vehicles equipped with LED headlights use integrated LED lighting for both low and high beams.
- Halogen daytime running lights use 9005; LED-headlight models use LED daytime running lights.
- Front turn signals and parking lights use 7444NA.
- Front side markers are 168NA with halogen headlights and LED with LED headlights.
- Reverse and rear turn signals use 921.
- Brake, center stop, tail, rear side-marker, and license-plate lighting are LED.
- Interior fitments include 194 or 7441 dome and trunk bulbs, 168 or 917 interior bulbs, 2886X map lights, and 7065 vanity lights.
Check the vehicle’s headlight type before ordering, particularly when replacing low-beam or high-beam components.
