Chevrolet City Express Luggage Compartment Bulb Size

Additional Notes

• The Chevrolet City Express uses the 168 bulb size for the luggage compartment across the 2015-2018 model years.
• The 168 bulb is classified as a miniature wedge type, designated T10, which refers to its tubular wedge-base form factor commonly used in low-current interior lighting positions.
• This bulb operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of cargo and interior illumination applications.
• The 168 designation follows the ANSI standard recognized in both the United States and Canada, meaning the specification applies uniformly across North American markets.
• The T10 wedge base design does not use a separate metal base or pins; instead, the glass envelope itself forms the connection point, which affects physical fitment and interchangeability with other base types.
• Because the 168 is an ANSI-standardized bulb, it is interchangeable with other bulbs sharing the same T10 wedge base and compatible voltage and wattage ratings, provided those substitutes meet the original electrical specifications.
