Additional Notes

The Buick Enclave map light uses the 168 bulb across all listed model years from 2008-2018.
The 168 is a miniature wedge-base bulb built to the T10 form factor, which refers to its tubular shape measured in eighths of an inch.
The wedge base design means the bulb is held in place by the socket contacts gripping the glass base directly, with no separate metal cap or pins involved.
The 168 bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
At 4.9 watts, the 168 is a low-wattage bulb, which is typical for interior courtesy and map lighting applications where prolonged use without engine load is common.
The 168 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined specification for electrical and physical characteristics.
Because the T10 wedge base is a widely shared form factor, several bulb numbers beyond the 168 share the same physical base, though wattage and voltage ratings may differ and substitution without verifying those values risks incorrect fitment.
