Additional Notes

The Hyundai XG350 tail light specifications cover the 2002-2005 model years, with two distinct bulb types used across that range.
The 1157 is an ANSI-standard dual-filament bulb operating at 12V with a 21W high filament and 5W low filament, mounted on a BAY15d bayonet base. It is specified for the 2004-2005 XG350.
The 2357 shares the same 12V operating voltage and BAY15d bayonet base as the 1157 but draws higher wattage at 26.9W and 8W across its two filaments. It is specified for the 2002-2003 XG350.
The BAY15d bayonet base is a two-pin offset base design. The offset pin placement ensures correct filament orientation, which is relevant to proper brake and running light function.
Both the 1157 and 2357 are dual-filament bulbs, meaning a single bulb serves two lighting functions simultaneously, typically combining the brake light and tail light roles in one unit.
The 2357 produces greater output than the 1157 due to its higher wattage rating. Although the two bulbs share the same BAY15d base, substituting one for the other across model years may result in output differences that fall outside original factory specifications.
