Additional Notes

The Chevrolet C-Series Pickup uses three distinct cornering bulb types across the 1993-2000 model years: the 2456, 3156, and 2356, all of which conform to ANSI standards recognized in both the United States and Canada.
The 3156 is the most frequently specified bulb across this range, appearing in the 1993-1995 and 1999 model years. It is a single-filament wedge bulb in the T25 form factor, rated at 12V and 27W.
The 2456 is a festoon-type bulb rated at 12V and is designated for specialty applications. It is specified for the 1997-1998 and 2000 model years.
The 2356 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V. It is specified exclusively for the 1996 model year.
The 3156 uses a wedge base, while the 2356 uses a BAY15d bayonet base and the 2456 uses a festoon mounting. These three bulb types are physically incompatible with one another due to their differing base designs.
The 1999 Chevrolet C-Series Pickup requires the 3156, while the adjacent 1998 and 2000 model years require the 2456. These years are not interchangeable in bulb fitment despite their proximity in the production range.
The dual-filament construction of the 2356 distinguishes it functionally from the single-filament 3156, as a dual-filament bulb supports two independent brightness levels within a single housing.
