Additional Notes

The H3 bulb is the most frequently specified front fog light bulb across the Chevrolet C-Series Pickup range, covering the 1988-1991 and 1994-1998 model years. It operates on a 12V, 55W rating and uses a PK22s base, conforming to the ECE standard used in Europe and worldwide, though it also carries approval in the US and Japan.
The 1999-2000 model years introduced a split specification, where the required front fog light bulb depends on the headlamp system installed on the vehicle. This makes headlamp type a critical compatibility factor for those years.
On the Chevrolet C-Series Pickup for 1999-2000, vehicles fitted with Halogen Capsule Headlamps use the 894 bulb, while those fitted with Sealed Beam Headlamps use the 880 bulb. These two bulbs are not interchangeable with each other.
The 894 and 880 bulbs both conform to the ANSI standard applicable in the US and Canada. Both are single-filament halogen bulbs operating at 12V, but they differ in wattage and base type. The 894 draws 37.5W and uses a PGJ13 base, while the 880 draws 27W and uses a PG13 base.
The PGJ13 base of the 894 and the PG13 base of the 880 are physically distinct from the PK22s base of the H3, meaning bulbs from the 1988-1998 fitment group are not compatible with the 1999-2000 split-specification fitment group.
The H3 bulb carries a notably higher wattage of 55W compared to the 37.5W of the 894 and the 27W of the 880, reflecting a different design generation and output level for the fog light circuit.
