Additional Notes

The Chevrolet Blazer front fog light specifications cover model years 1993-2003, with three distinct bulb types used across that span: H3, 880, and 881.
The H3 bulb follows the ECE standard, which governs lighting regulations in Europe and many other markets worldwide, though it also carries approval in the US and Japan. It uses a PK22s base and operates at 12V with a 55W output.
The 880 and 881 bulbs both follow the ANSI standard, which applies to the US and Canada. Both operate at 12V and 27W, roughly half the wattage of the H3 used in earlier model years.
The 880 and 881 bulbs are distinguished by their base types. The 880 uses a PG13 base, while the 881 uses a PGJ13 base. These two base types are not interchangeable, despite the bulbs sharing identical voltage and wattage ratings.
The Chevrolet Blazer (1993-1996) front fog lights use the H3 bulb. The specification shifts to the 880 for 1997-1999 and then to the 881 for 2000-2003, meaning three separate bulb types were used across the full production run covered by these specifications.
The base type change between the 880 and 881 is a critical fitment detail. Although both bulbs are rated at 12V and 27W, the differing base designs mean a bulb from one group will not physically seat correctly in a housing designed for the other.
