Additional Notes

The Lincoln Mark LT uses the 906 bulb for the map light across its 2006-2008 model years.
The 906 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The 906 belongs to the T10 miniature wedge family, a form factor defined by a wedge-shaped base that connects directly into a socket without a separate metal cap or pins.
The bulb operates at 12 volts and draws 8 watts, figures consistent with low-current interior lighting applications in passenger vehicles.
The T10 wedge base is a widely produced form factor, and the 906 designation specifically identifies the electrical rating within that family, meaning not all T10 wedge bulbs are interchangeable with the 906 despite sharing the same base type.
