Additional Notes

The 906 bulb is the glove box bulb size for the Cadillac CTS across all years listed in the specifications, covering 2008-2013 and 2016-2019.
The 906 is an ANSI-standardized bulb type, meaning its physical and electrical characteristics follow a defined North American standard recognized in both the United States and Canada.
This bulb follows the T10 miniature wedge form factor, which uses a wedge-shaped base that seats 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 illumination applications such as glove box lighting.
The T10 wedge base is a widely produced form factor, and the 906 designation specifically defines the wattage and voltage within that base category, so not all T10 bulbs are interchangeable with the 906.
