Additional Notes

The Mazda B4000 map light draws from four distinct bulb sizes across its production span: 904, 168, 211-2, 906, and 212-2, reflecting multiple hardware revisions over the years.
The 904 is a T10 miniature wedge bulb rated at 12V and 8W under the ANSI standard, and it is the most frequently specified map light bulb for the Mazda B4000, covering model years 2000-2002 and 2006-2009.
The 906 is also a T10 miniature wedge bulb rated at 12V and 8W, sharing the same wattage and base type as the 904, though the two carry different ANSI designations and are not confirmed as interchangeable within these specifications.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, making it the lowest-wattage option among all bulbs listed, and it applies to the 2003-2005 model years.
The T10 wedge base is the most common base type across the B4000 map light specifications, shared by the 904, 906, and 168 bulbs, though wattage differences among them are a relevant fitment consideration.
The 211-2 is a festoon-style bulb with an SV8.5 base and a 41mm length, rated at 12V and 12W, and it is specified for the 1995, 1997, and 1999 model years.
The 212-2 is also a festoon-style bulb with an SV8.5 base and a 41mm length, rated at 12V and 12W, making its electrical and physical characteristics identical to the 211-2, though the two carry separate ANSI designations.
The 212-2 applies exclusively to the 1994 Mazda B4000, while the 211-2 covers 1995, 1997, and 1999, meaning the two similarly specified festoon bulbs are assigned to different model years without overlap.
The 906 applies to the 1996 and 1998 model years, while surrounding years in that same period use festoon-type bulbs, indicating a non-uniform fitment pattern across mid-1990s production.
Because the T10 wedge bulbs in these specifications differ in wattage (4.9W for the 168 versus 8W for the 904 and 906), substituting one T10 bulb for another across different model years carries a wattage mismatch risk.
