Additional Notes

The Hyundai XG350 front fog light position lists two bulb sizes across the 2002-2005 model years: the 9006 and the H3. Both are single-filament halogen bulbs rated at 12V and 55W, making them electrically equivalent in output.
The 9006 follows the ANSI standard used in the United States and Canada. It uses a P22d base, which is a push-and-twist locking connector specific to that standard and not physically interchangeable with European-style bases.
The H3 follows the ECE standard used in Europe and worldwide, with a PK22s base. Unlike the 9006, the H3 holds regulatory approval in the US and Japan in addition to ECE-regulated markets.
Although the 9006 and H3 share the same voltage and wattage ratings, their bases differ. The P22d base of the 9006 and the PK22s base of the H3 are not compatible with each other, meaning one cannot be substituted for the other without a corresponding socket change.
For the 2003 model year, the H3 fitment carries a production date qualifier, applying only to units built through February 1, 2003. The 9006 listing for 2003 carries no such date restriction.
The presence of two listed bulb sizes for the same fog light position across the same model years indicates that the XG350 was produced with different socket configurations depending on the market or production variant.
