Additional Notes

The Chevrolet Equinox front fog light uses two distinct bulb types across its model years: the H11 from 2005-2015 and the H8 from 2016-2021.
The H8 bulb operates at 12 volts and 35 watts, making it a lower-wattage halogen unit compared to the H11, which runs at 12 volts and 55 watts.
Both the H8 and H11 are single-filament halogen bulbs, meaning each bulb controls only one lighting function rather than switching between two beam modes.
The H8 uses a PGJ19-1 base, while the H11 uses a PGJ19-2 base. These two base types are physically distinct and are not interchangeable with each other.
The Chevrolet Equinox (2016-2021) requires the H8 bulb specifically. Installing an H11 in its place is not a direct fit due to the differing base configurations.
Both bulb types conform to ECE standards, which govern lighting equipment across Europe and many other markets worldwide, and both carry approval for use in the United States as well.
The 20-watt difference between the H8 and H11 reflects a meaningful gap in power draw, with the H11 consuming more energy per hour of operation.
The shared PGJ19 base family between the H8 and H11 indicates a close physical relationship, but the differing suffix numbers (PGJ19-1 versus PGJ19-2) denote a key structural variation that prevents cross-fitting.
