Additional Notes

The T10 miniature wedge is the bulb format used in the Suzuki SX4 license plate position, appearing across both recorded model years for this application.
The 168 designation follows ANSI standards as applied in the United States and Canada, placing it within a regulated specification framework for miniature automotive lighting.
At 12 volts and 4.9 watts, the 168 bulb operates on the standard automotive electrical system voltage while drawing a relatively low wattage typical of license plate illumination.
The T10 designation refers to the bulb's tubular envelope, with the number indicating a width of 10 eighths of an inch, a sizing convention common to miniature wedge bulbs.
The wedge base design means the bulb is held in its socket by the tension of the base itself rather than by a separate bayonet or screw mechanism, which affects how it is seated and removed.
The 168 and the closely related 194 are both T10 wedge bulbs, though they differ in wattage. Substituting one for the other without confirming socket and circuit compatibility may result in incorrect light output or electrical load.
