Additional Notes

The Ram 1500 uses the 194 bulb size for the license plate position across the 2011-2019 model years.
The 194 bulb is a T10 miniature wedge type, which refers to its wedge-shaped base that holds the bulb in place without a separate metal connector or socket pins.
This bulb operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The 194 designation follows ANSI standards recognized in both the United States and Canada, meaning the specification is consistent across North American markets.
T10 wedge bulbs are widely produced in both incandescent and LED formats, and the wedge base design allows direct physical substitution between these technologies in most applications.
Because the 194 is an ANSI-standardized bulb, it is interchangeable with other bulbs sharing the same T10 wedge base and compatible voltage rating, provided wattage and fitment requirements are met.
