Additional Notes

The Mazda B2300 dome light specifications cover model years 1995-1997 and 2001-2009, with bulb requirements varying across that span.
The 912 bulb is the sole dome light specification for the Mazda B2300 across the 2003-2009 model years, making it the most consistently specified bulb type in these listings.
The 912 is a T15 wedge-base bulb rated at 12V and 12W, and it is classified as a variant of the 921 bulb under the ANSI standard used in the US and Canada.
The 211-2 is a festoon-style bulb with an SV8.5 base and a 41mm length, rated at 12V and 12W, and it also follows the ANSI standard for the US and Canadian markets.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, which is a notably lower wattage than either the 912 or the 211-2.
For the 2001-2002 model years, the correct dome light bulb depends on whether the vehicle was built with a map light. Vehicles with a map light take the 211-2, while those without take the 168.
The fitment split in 2001-2002 means the 912 and the 211-2 are not interchangeable for those years, as each corresponds to a distinct factory configuration.
The 1995-1997 model years share a single dome light specification, the 211-2, with no conditional fitment noted.
Although the 912 and the 211-2 share the same 12V and 12W ratings, they use different base types, a wedge base versus an SV8.5 festoon base, which makes them physically incompatible with each other's sockets.
