Additional Notes

The Peterbilt 587 front fog light uses the H3 bulb across all listed model years, spanning 2011-2018.
The H3 is a single-filament halogen bulb, meaning it contains one tungsten filament enclosed within a halogen gas-filled quartz envelope, which produces light through the halogen regenerative cycle.
H3 bulbs operate at 12 volts and 55 watts, placing them in the standard low-wattage halogen range typical of automotive fog light applications.
The H3 uses a PK22s base, which is a single-pin push-on connector. This base type is distinct from the more common two-pin or wedge-style bases found in other halogen families, and substitution with physically incompatible base types is not supported by these specifications.
The H3 is an ECE-rated bulb, meaning it conforms to the Economic Commission for Europe lighting standards, which govern photometric output and construction requirements across European and many worldwide markets.
Despite its ECE origin, the H3 also carries approval for use in the United States and Japan, giving it broad regulatory acceptance across major automotive markets.
