Additional Notes

The Ford F-450 Super Duty license plate position uses two bulb sizes across its model years: the 168 and the 194. Both are ANSI-standardized miniature wedge bulbs of the T10 type, operating on a 12V circuit.
Although the 168 and 194 share the same T10 wedge base and 12V rating, they are not interchangeable. The 168 draws 4.9W while the 194 draws 3.78W, making them electrically distinct despite their physical similarities.
The 168 bulb is the more widely used of the two across the F-450 Super Duty's production span, appearing in the 1999-2010 and 2017-2022 model years.
The 194 bulb applies to the 2011-2016 model years of the Ford F-450 Super Duty for the license plate position.
For the 2017-2019 model years, the 168 bulb size is specified only for vehicles equipped with Halogen Capsule Headlamps, indicating that headlamp configuration is a relevant fitment variable for those years.
The T10 wedge base is a common miniature bulb format used in low-intensity automotive lighting applications such as license plate illumination, instrument panels, and courtesy lights.
Both the 168 and 194 carry ANSI standardization recognized in the United States and Canada, meaning their electrical and physical specifications conform to a defined industry standard in those markets.
