Isuzu Oasis Map Light Bulb Size

Additional Notes

• The 168 bulb is the map light specification for the Isuzu Oasis across all listed model years, covering 1996-1999.
• The 168 bulb follows the ANSI standard, meaning it conforms to a recognized North American specification used in both the United States and Canada.
• It belongs to the T10 miniature wedge base family, a base type that relies on two angled legs pressed directly into a socket rather than a threaded or bayonet-style mount.
• The bulb operates at 12 volts, consistent with standard automotive electrical systems.
• At 4.9 watts, the 168 produces a relatively low power draw, typical of interior courtesy and map lighting applications.
• The wedge base design of the T10 format means the glass envelope itself acts as the retention mechanism within the socket, with no separate metal base required.
• Because the 168 is an ANSI-standardized bulb, it is produced by multiple manufacturers to the same electrical and physical specification, making cross-brand substitution generally straightforward within that standard.
• The consistent use of the same bulb size across all four model years indicates no mid-cycle change was made to the map light socket specification during the Oasis production run covered by these records.
