Additional Notes

The 9005 bulb is the most widely used type across Toyota Avalon high beam headlight specifications, covering model years 1995-2018 with the exception of 2008-2010. It is an ANSI-standard single-filament halogen bulb rated at 12V and 65W with a P20d base.
The 9006 bulb holds a similarly dominant position in low beam headlight specifications, appearing across model years 1995-2007 for halogen-equipped trims. It is an ANSI-standard single-filament halogen bulb rated at 12V and 55W with a P22d base.
The Toyota Avalon (2013-2018) uses the 9005 bulb for both high beam and low beam positions on halogen-equipped trims, meaning a single bulb type serves dual functions in those configurations.
Although the 9005 and 9006 share a similar ANSI halogen construction, their bases differ, P20d versus P22d respectively, making them physically non-interchangeable despite their close numerical designation.
The 9011 bulb was used exclusively for high beam headlights on the 2008-2010 Avalon. While it shares the same 12V and 65W rating as the 9005, it uses a PX20d base rather than a P20d base, which means it is not a direct drop-in replacement for the 9005.
For model years 2011-2018, halogen low beam trims transitioned from the 9006 to the H11 (2011-2012) and then to the 9005 (2013-2018). The H11 is an ECE-standard bulb rated at 12V and 55W with a PGJ19-2 base, distinct from both the 9005 and 9006 in base type and wattage.
HID low beam options on the 2005-2007 Avalon use the D2R bulb, which operates at 85V and 35W and requires an external ignitor. It is designed for reflector-type housings and uses a P32d-3 base.
The D4R bulb, used for HID low beams on the 2008-2010 Avalon, is a mercury-free successor to the D2R. It also targets reflector-type housings but uses a P32d-6 base and operates at 42V, making it incompatible with D2R sockets.
The D4S bulb, used for HID low beams on the 2011-2018 Avalon, is also mercury-free and operates at 42V and 35W, but it uses a P32d-5 base and is designed for projector-type housings, distinguishing it from the reflector-oriented D4R despite sharing the same voltage and wattage.
The 2018 Avalon high beam headlight specification includes a halogen capsule condition note, indicating that the 9005 fitment applies only to trims equipped with halogen headlamps rather than to all configurations universally.
