Additional Notes

The two bulb types specified for the Jeep Grand Cherokee license plate position are the 7440 and the 168, both of which conform to ANSI standards recognized in the United States and Canada.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W, placing it in the low-wattage category typical of license plate and courtesy lighting applications.
The 7440 is a T20 single-filament wedge bulb rated at 12V and 21W, a significantly higher wattage than the 168, which reflects a different electrical load requirement.
The single-filament construction of the 7440 means it serves one lighting function only, as opposed to dual-filament bulbs that handle two functions such as running and brake light within a single housing.
The Jeep Grand Cherokee (2014-2016) uses the 7440 for the license plate position, while model years 1993-2011 use the 168, indicating a change in bulb specification between these two production periods.
The T10 and T20 designations refer to the tubular envelope size of each bulb, with T10 being the smaller of the two formats represented in these specifications.
Because the 7440 and 168 use different wedge base sizes (T20 versus T10), the two bulb types are not interchangeable with each other.
The 1993-2011 model years share a single consistent bulb specification, making the 168 the dominant bulb type across the Grand Cherokee license plate fitment data provided.
