Additional Notes

The Dodge Ram 1500 uses one of two bulb sizes for the license plate position across the 1994-2010 model years: the 194 and the 168.
Both the 194 and the 168 are ANSI-standardized miniature wedge bulbs classified under the T10 form factor, meaning they share the same physical wedge-base housing style.
Despite sharing the T10 form factor, the 194 and the 168 are not electrically identical. The 194 operates at 3.78W while the 168 operates at 4.9W, both on a 12V circuit.
The wattage difference between the two bulbs is a relevant fitment consideration, as substituting one for the other introduces a mismatch with the original circuit load specification for that model year.
The Dodge Ram 1500 (2010) is the only model year in these specifications that calls for the 194 bulb in the license plate position.
The 168 bulb is specified for the Dodge Ram 1500 across the 1994-2009 model years, covering the full span of the remaining entries in these specifications.
Both bulb types carry ANSI standardization recognized in the United States and Canada, indicating conformance to a defined set of performance and dimensional criteria within those markets.
