Additional Notes

The 168 bulb is the most frequently specified license plate bulb for the Dodge Ram 3500 Van, covering model years 1999-2000 and 2002-2003.
The 168 bulb follows the ANSI standard recognized in both the United States and Canada, and is classified as a T10 miniature wedge type operating at 12 volts and 4.9 watts.
The T10 wedge base design means the 168 bulb is inserted directly into a socket without any rotation, relying on friction rather than a locking mechanism to hold it in place.
The 2001 Dodge Ram 3500 Van uses the 67 bulb for the license plate position, which differs from every other model year listed in these specifications.
The 67 bulb also conforms to the ANSI standard for the US and Canada, but uses a BA15s bayonet base rather than a wedge fitting, making it physically incompatible with sockets designed for the 168.
At 8 watts, the 67 bulb draws noticeably more power than the 4.9-watt 168, and both operate on a 12-volt circuit.
The 67 bulb is a single-filament design and is described as a lower wattage variant of the 1156, sharing the same BA15s bayonet base as that bulb type.
Because the 168 and 67 bulbs use entirely different base types, wedge versus bayonet, they are not interchangeable across the model years listed in these specifications.
