Pontiac Aztek Map Light Bulb Size

Additional Notes

• The Pontiac Aztek uses the 906 bulb for the map light across all listed model years, spanning 2001-2005.
• The 906 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the US and Canada.
• This bulb follows the T10 miniature wedge form factor, which refers to a small wedge-shaped base that connects directly into a socket without a separate metal cap or pins.
• The 906 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
• At 8 watts, the 906 draws a relatively low amount of power, which is typical for interior courtesy and reading light applications.
• The wedge base design of the T10 bulb means it is held in place by the tension of the socket itself rather than by a bayonet or screw mechanism.
• Because the 906 is an ANSI-designated bulb, it is produced by multiple manufacturers to the same standardized output and base specifications, which generally allows for cross-brand substitution within the same ANSI number.
• The single bulb size listed across the entire 2001-2005 production run indicates no mid-cycle change was made to the map light socket or bulb specification for the Aztek during that period.
