Scion tC Headlight Bulb Size

Scion tC headlight bulbs utilize 9012, 9005, H11, and 9006 sizes depending on beam type and model year, with high beam applications requiring either 9012 or 9005 bulbs and low beam applications requiring 9012, H11, or 9006 bulbs. The replacement chart covers 2005 through 2016 production years with corresponding bulb size specifications.

Additional Notes

The 9012 bulb follows the ANSI standard used in the US and Canada. It is a single-filament enhanced halogen type with a PX22d base, rated at 12V and 55W. The Scion tC uses this bulb for both high and low beam positions in the 2014-2016 model years, making it the only bulb in these specifications to serve a dual-beam role within a single vehicle generation.
The 9005 is a single-filament halogen bulb with a P20d base, rated at 12V and 65W under the ANSI standard. At 65W, it draws more power than the other bulb types listed in these specifications. The Scion tC uses it exclusively in the high beam position for the 2005-2013 model years.
The H11 follows the ECE standard, which governs lighting regulations across Europe and much of the world, though it also carries approval for use in the United States. It is a single-filament halogen bulb with a PGJ19-2 base, rated at 12V and 55W. The Scion tC uses it in the low beam position for the 2009-2013 model years, and the 2008 model year uses it specifically when equipped with projector-type headlamps.
The 9006 is a single-filament halogen bulb with a P22d base, rated at 12V and 55W under the ANSI standard. The Scion tC uses it in the low beam position for the 2005-2007 model years, and the 2008 model year uses it when the vehicle is not equipped with projector-type headlamps.
The 2008 Scion tC low beam fitment is split between two bulb types depending on headlamp configuration. Projector-type headlamps require an H11 bulb, while non-projector headlamps require a 9006. These two bulbs have different base types, PGJ19-2 and P22d respectively, and are not interchangeable.
Although the 9012 and 9006 are both rated at 12V and 55W, they use different base types, PX22d and P22d respectively, and are not interchangeable. The physical base configurations are distinct, and substituting one for the other is not supported by these specifications.
The 9005 and 9006 are both ANSI-standard halogen bulbs sharing a similar base family, but the 9005 uses a P20d base while the 9006 uses a P22d base. Their wattage also differs, with the 9005 rated at 65W and the 9006 at 55W. These differences make them non-interchangeable despite their similar designations.
Across the full model range of the Scion tC, the high beam position uses one of two bulb types: the 9005 for 2005-2013 and the 9012 for 2014-2016. The low beam position uses one of three bulb types across the same span, reflecting a broader range of fitment variation on that side of the headlamp assembly.
