Toyota Matrix Headlight Bulb Size

Additional Notes

• The Toyota Matrix uses the 9005 bulb for high beam headlights across all model years from 2003-2013, and the 9006 bulb for low beam headlights across that same production span.
• Both the 9005 and 9006 are ANSI-standardized halogen bulb types recognized in the United States and Canada, meaning they conform to a defined set of electrical and physical specifications rather than being proprietary fitments.
• The 9005 is a single-filament halogen bulb rated at 12 volts and 65 watts, mounted on a P20d base. The higher wattage reflects its role in producing the stronger output required for high beam operation.
• The 9006 is also a single-filament halogen bulb rated at 12 volts but draws 55 watts, and it uses a P22d base. The lower wattage corresponds to the reduced output used for low beam illumination.
• Although the 9005 and 9006 share a similar appearance, their bases differ: the P20d base on the 9005 and the P22d base on the 9006 are not interchangeable. Physically, the locking tabs on each bulb are positioned differently, which prevents cross-installation between the two positions.
• Because both bulb types are single-filament designs, each serves only one lighting function. A dual-filament bulb, by contrast, would handle both high and low beam duties from a single unit, which is not the case here.
• The consistent use of 9005 and 9006 across all eleven model years of the Toyota Matrix means that replacement bulbs sourced for any year within the 2003-2013 range are electrically and physically equivalent to those required by any other year in that range.
