The Chrysler PT Cruiser brake light utilizes 3157 and 2458 bulb sizes according to the provided specifications for the lighting system. Data for the specific components covers the range from 2001 to 2010.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler PT Cruiser uses the 3157 bulb for its brake lights across the entire 2001-2010 model range.
The 3157 is a dual-filament bulb, meaning it serves two brightness levels within a single unit, typically supporting both running light and brake light functions through separate filaments rated at 7W and 27W respectively.
The 3157 follows the T25 wedge form factor and operates on a 12V system, which is standard for passenger vehicles of this era.
The center high mount stop light on the Chrysler PT Cruiser uses the 921 bulb across the full 2001-2010 model range.
The 921 is a single-filament wedge bulb rated at 16W, which reflects its dedicated stop light function rather than a dual-purpose role.
The 921 follows the T15 wedge form factor, making it physically smaller than the T25 3157 used in the main brake light positions.
Both the 3157 and 921 conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances across those markets.
The 3157 and 921 are not interchangeable with each other, as they differ in filament count, wattage, and physical form factor.
