Ford F-450 Super Duty Map Light Bulb Size

Additional Notes

• The Ford F-450 Super Duty uses the 906 bulb size for its map light across the 2011-2016 model years.
• The 906 is a miniature wedge-type bulb, classified under the T10 form factor, which refers to a tubular bulb body approximately 10 millimeters wide at its widest point.
• The wedge base design means the bulb is held in place by the socket gripping the glass envelope directly, with no separate metal base or pins involved.
• The 906 bulb 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 light applications.
• The 906 designation follows ANSI standardization, meaning it is a recognized specification in both the United States and Canada, and bulbs from different manufacturers carrying this number share the same electrical and physical characteristics.
• Because the 906 is an ANSI-standardized wedge bulb, aftermarket and OEM replacements from various manufacturers are generally interchangeable as long as the 906 designation is confirmed on the packaging.
• The T10 wedge form factor is shared by several other ANSI bulb numbers, so substituting a visually similar T10 bulb with a different designation risks a mismatch in wattage or voltage rating.
