Additional Notes

The two bulb types specified for the Suzuki Grand Vitara map light across model years 1999-2005 are the 168 and the PC168, both of which are ANSI-standard miniature wedge bulbs classified under the T10 form factor.
Both the 168 and PC168 operate at 12 volts, making them compatible with standard automotive electrical systems.
The 168 bulb carries a rated output of 4.9 watts, placing it in the low-wattage range typical of interior courtesy and map lighting applications.
The PC168 is a variant of the T10 wedge bulb fitted with a printed circuit board twist-lock socket, a design intended specifically for instrument cluster and similar panel-mounted applications.
Despite sharing the same T10 wedge form factor, the 168 and PC168 use different socket interfaces. The 168 uses a standard wedge base, while the PC168 uses a twist-lock printed circuit board socket, meaning the two are not directly interchangeable without a compatible socket housing.
The Suzuki Grand Vitara (1999-2003) uses the 168 bulb for the map light position across all five of those model years.
The 2004-2005 Grand Vitara transitions to the PC168 specification for the map light, reflecting a socket change relative to earlier model years.
