For the 2014 Toyota Avalon, high-beam headlights use a 9005 bulb. Low-beam fitment depends on the headlight system: models with halogen headlights use 9005, while models with HID headlights use D4S. The daytime running light also follows this distinction, using 9005 with halogen headlights and an LED assembly with HID headlights.
Fog-light listings include H11 LED and H16 LED applications, so verify the existing socket and assembly before ordering. The front turn signal and parking light use 7444NA, while the front side marker uses 168NA. Reverse lights and rear turn signals use 921 bulbs.
Several rear lighting functions are LED, including the brake lights, center stop light, tail lights, and rear side markers. Interior and utility fitments include 168 or 917 for courtesy and other interior locations, 194 or 7441 for dome and trunk lights, 2886X for map lights, and 7065 for vanity lights. License-plate lighting is listed as 168 or 917.
