Mazda RX-7 Map Light Bulb Size

Additional Notes

• The Mazda RX-7 uses the 168 bulb size for the map light across all listed model years from 1988-1995, with the exception of 1992, which is not present in the specifications.
• The 168 bulb is an ANSI-standardized type, meaning its electrical and physical characteristics conform to a defined North American specification used across many vehicle manufacturers.
• This bulb operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of interior courtesy and reading lights.
• The 168 belongs to the T10 miniature wedge family, a form factor in which the base of the bulb itself acts as the connector, with no separate metal pins or bayonet fittings involved.
• The wedge base design of the T10 means the bulb is held in its socket by friction rather than a locking mechanism, allowing for tool-free removal in most applications.
• Because the 168 is an ANSI-standardized wedge bulb, it is broadly interchangeable with other T10 wedge types that share the same voltage and wattage ratings, though socket fit should be confirmed before substitution.
• The consistent use of the 168 bulb across all listed model years of the Mazda RX-7 indicates a stable map light socket specification throughout that production span.
