Additional Notes

The Chevrolet Lumina APV uses the 906 bulb for the map light across all model years from 1990 to 1996.
The 906 is an ANSI-standardized bulb, 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, a base type that relies on two angled plastic legs to friction-fit into a socket rather than using a metal screw or bayonet base.
The 906 operates at 12 volts, which is consistent with standard automotive electrical systems.
At 8 watts, the 906 draws a relatively low amount of power, typical of interior courtesy and reading lamp applications.
The wedge base design of the T10 means that fitment depends on socket compatibility with that specific base style, and bulbs with bayonet or festoon bases are not interchangeable with this application.
