Additional Notes

The Suzuki Vitara uses the 168 bulb size for the map light across the 1999-2003 model years.
The 168 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American industry standard applicable in both the US and Canada.
This bulb follows the T10 form factor, a miniature wedge-base design that seats by friction fit rather than by a twist-lock or bayonet mechanism.
The 168 operates at 12 volts, which is consistent with standard automotive electrical systems.
At 4.9 watts, the 168 is a low-wattage bulb, typical of interior courtesy and map lighting applications where prolonged use and minimal heat output are relevant factors.
The wedge base of the T10 form factor means the bulb's glass envelope and wire leads form the base itself, with no separate metal cap, which affects physical fitment in the socket.
Because the 168 is an ANSI-standardized type, other bulbs sharing the same T10 wedge base and 12V/4.9W rating may be electrically and physically interchangeable, provided they conform to the same standard.
