Dodge Caravan License Plate Bulb Size

Additional Notes

• The Dodge Caravan uses the 168 bulb for the license plate position across all model years listed in the specifications, spanning 1984-1993 and 1996-2007.
• The 168 is classified as a T10 miniature wedge bulb under the ANSI standardization system recognized in both the United States and Canada.
• The T10 designation refers to the bulb's tubular shape, with the number indicating its width in units of one-eighth of an inch, placing it in the smaller end of the miniature bulb range.
• The 168 bulb operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
• At 4.9 watts, the 168 bulb draws a low level of power, a characteristic typical of license plate lighting, which is a continuously active position when the vehicle's lights are on.
• The wedge base design of the 168 means the bulb is held in its socket by the tension of the base contacts rather than by a bayonet or screw mechanism, making it a tool-free replacement in most housings.
• Because the 168 is an ANSI-standardized type, it is interchangeable with other bulbs sharing the T10 wedge form factor and the same voltage and wattage ratings, provided the replacement meets those electrical specifications.
• Substituting a bulb with a higher wattage than 4.9W in the license plate socket carries a risk of exceeding the thermal tolerance of the housing, since the socket is designed around the heat output of the original specification.
