Mazda B2500 Dome Light Bulb Size

Additional Notes

• The 211-2 is the dominant bulb type across the Mazda B2500 dome light specifications, appearing in the 1998-2000 model years without condition and in the 2001 model year for vehicles equipped with a map light.
• The 211-2 is a festoon-style bulb with an SV8.5 base and a 41mm length, operating at 12 volts and 12 watts under the ANSI standard applicable to the US and Canadian markets.
• The SV8.5 base designation refers to a cylindrical festoon format where the bulb makes contact at both ends rather than through a keyed or wedge-style socket, which is a physically distinct mounting method from the 168 bulb used in the same vehicle.
• The 2001 Mazda B2500 is the only model year in these specifications where dome light bulb fitment varies by trim or equipment level, with the 211-2 assigned to map light-equipped vehicles and the 168 assigned to those without a map light.
• The 168 is a T10 miniature wedge bulb operating at 12 volts and 4.9 watts, which represents a significantly lower wattage than the 211-2, reflecting its use in a lower-output lighting position on non-map light 2001 B2500 vehicles.
• The 211-2 and 168 are not interchangeable, as they differ in base type, physical form, wattage, and socket compatibility, making the presence or absence of a map light a critical factor in determining the correct fitment for 2001 B2500 dome light replacement.
• Both the 211-2 and 168 conform to ANSI standards recognized in the United States and Canada, classifying them as standardized bulb types rather than proprietary or manufacturer-specific components.
