Mazda 6 Headlight Bulb Size

Additional Notes

• The 9005 bulb is the most frequently specified high beam type across the Mazda 6 range, appearing in model years 2011-2017 for halogen-equipped variants. It is an ANSI-standard single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base.
• The H1 bulb served as both the high beam and low beam source in the Mazda 6 for model years 2003-2008 in halogen configurations. Operating at 12V and 55W with a P14.5s base, it is an ECE-standard single-filament halogen type recognized in the US and Japan.
• The D2S bulb is the HID low beam type used in the Mazda 6 from 2006-2013 in HID-equipped variants. It operates at 85V and 35W, uses a P32d-2 base, and requires a separate external ignitor. It is designed exclusively for projector-type housings.
• The D4S bulb replaced the D2S as the HID type for both high and low beam positions in 2014-2015 HID-equipped variants. Unlike the D2S, the D4S is mercury-free, operates at 42V and 35W, and uses a P32d-5 base, making the two types electrically and physically incompatible with each other.
• Model years 2014-2015 of the Mazda 6 present a dual-fitment situation where a single year accommodates either HID or halogen headlamp systems. The HID configuration uses D4S bulbs for both beams, while the halogen configuration uses 9005 for high beam and H11 for low beam.
• The H11 low beam bulb, used in 2016-2017 halogen variants, and the H9 high beam bulb, used in 2009-2010, share the same ECE standard family but carry different base types. H11 uses a PGJ19-2 base at 55W, while H9 uses a PGJ19-5 base at 65W, and the two are not interchangeable despite their physical similarity.
• The H7 bulb served as the halogen low beam type from 2009-2013. It operates at 12V and 55W with a PX26d base and is an ECE-standard type approved in the US and Japan. Its base type differs from the H1 it succeeded in that role, meaning the two are not interchangeable.
