Pontiac Montana License Plate Bulb Size

Additional Notes

• The Pontiac Montana uses two bulb types for its license plate light across its model years: the 194 and the 168, both of which are ANSI-standardized miniature wedge bulbs classified under the T10 form factor.
• Both the 194 and 168 bulbs operate at 12 volts, making them compatible with standard automotive electrical systems.
• The 168 bulb draws 4.9 watts, while the 194 draws 3.78 watts, meaning the two types differ in power consumption despite sharing the same T10 wedge form factor.
• Because the 194 and 168 share the T10 wedge base, they are physically interchangeable in terms of socket fit, but their wattage difference means they are not electrically identical replacements for one another.
• The 168 bulb is the specified fitment for the Pontiac Montana from 1999-2004, as well as for 2005 models equipped with 2 headlamps.
• The 194 bulb applies to the 2006 Montana and to 2005 models equipped with 4 headlamps, indicating that the headlamp configuration on 2005 vehicles is a determining factor in license plate bulb selection.
• The 2005 model year is the only year in these specifications where two distinct license plate bulb sizes are listed, with fitment dependent on whether the vehicle has a 2-headlamp or 4-headlamp arrangement.
• Both bulb types carry ANSI standardization recognized in both the United States and Canada, reflecting a shared North American automotive lighting standard.
