Chevrolet Express brake bulb sizes include 3157, 2458, and 2057, while the center high mount stop light uses a 912 bulb size. The replacement chart covers vehicle production years from 1996 to 2022 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 3157 is the most widely used brake bulb across the Chevrolet Express range, appearing in 2006-2022 models universally and in 2500/3500/4500 trims from 2003-2005 and 2008-2014. It is a dual-filament T25 wedge bulb rated at 12V with a high-beam filament of 27W and a low-beam filament of 7W, conforming to ANSI standards for the US and Canada.
The 912 wedge bulb serves as the center high mount stop light across the entire model range from 1996-2022 without variation by trim level. It is a T15 wedge type rated at 12V and 12W, and it is a variant of the 921 bulb.
The 2057 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with filaments of 26.9W and 8W. It is noted as a brighter variant of the 1157 and was the brake bulb used across all Express trims from 1996-2002.
The 2458 bulb is specified exclusively for the Express 1500 trim in brake light applications. It applies to model years 2003-2014, with the exception of 2006 and 2007, during which all trims used the 3157.
In 2013-2014, the Chevrolet Express carries two distinct brake bulb specifications depending on trim: the 1500 uses the 2458, while the 2500, 3500, and 4500 use the 3157. These two bulbs are not interchangeable due to differing base types and wattage ratings.
The 3157 and 2057 are both dual-filament bulbs, but they use different base configurations. The 3157 uses a wedge base while the 2057 uses a BAY15d bayonet base, making them physically incompatible with each other despite serving the same brake light function across different model years.
From 2015-2022, the Express standardized on a single brake bulb, the 3157, across all trim levels, eliminating the trim-specific split that existed in earlier model years.
The 912 and 3157 are both wedge-type bulbs, but they differ significantly in wattage and physical size. The 912 is a T15 rated at 12W, while the 3157 is a T25 rated at 27W/7W. They serve different lighting positions and are not interchangeable.
