Mazda B2300 Map Light Bulb Size

The Mazda B2300 map light utilizes bulb sizes 904, 168, 211-2, and 212-2 depending on the specific version of the vehicle. Available data covers a range from 1994 through 2009 for the components listed.

Additional Notes

The Mazda B2300 map light draws from three distinct bulb types across its model years: the 904, 168, and 211-2/212-2 series, all conforming to ANSI standards applicable in the US and Canada.
The 904 bulb is the most frequently specified type for the Mazda B2300 map light, appearing across the 2001-2002 and 2006-2009 model years.
The 904 is a T10 miniature wedge bulb rated at 12V and 8W. The T10 designation refers to a tubular envelope roughly 10/8 of an inch wide, with a wedge-style base that requires no separate socket locking mechanism.
The 168 bulb is also a T10 miniature wedge type but is rated at a lower 4.9W, making it electrically distinct from the 904 despite sharing the same base form factor. It is specified for the 2003-2005 model years.
Because the 904 and 168 share the T10 wedge base, one may physically fit where the other is specified, but their wattage difference means they are not confirmed interchangeable replacements per these specifications.
The 1995-1997 model years use the 211-2, a festoon-style bulb with an SV8.5 base rated at 12V and 12W. Festoon bulbs are cylindrical lamps held in place by spring-loaded end caps rather than a socket, and the SV8.5 designation refers to the base contact style.
The 1994 model year is specified with the 212-2, which shares the same 41mm festoon length, SV8.5 base, 12V rating, and 12W output as the 211-2. Despite near-identical published specifications, the two carry separate ANSI designations and are not listed as interchangeable within these specifications.
The transition from the festoon-type 211-2 to the wedge-type 904 between the 1997 and 2001 model years reflects a change in the physical bulb format required for the map light housing across those generations.
At 12W, the festoon bulbs specified for the 1994-1997 B2300 draw notably more power than either the 904 at 8W or the 168 at 4.9W, which is relevant when considering socket and wiring compatibility.
Fitment accuracy depends on matching both the bulb number and the model year, as the B2300 map light specification changes across multiple points in its production run and no single bulb type covers all years.
