Saturn L200 brake bulbs utilize a 3157 size, while the center high mount stop light requires a PC168 bulb size. The replacement chart covers 2001 to 2003 vehicle production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Saturn L200 uses the 3157 bulb for brake lights across the 2001-2003 model years.
The 3157 is a dual-filament bulb, meaning it serves two brightness levels within a single unit, typically handling both running light and brake light functions simultaneously.
At 12V with a 27W/7W rating, the 3157 draws 27 watts on its high-intensity filament and 7 watts on its low-intensity filament.
The 3157 follows the T25 wedge form factor and conforms to ANSI standards applicable in both the United States and Canada.
The center high mount stop light on the Saturn L200 uses the PC168 bulb across the 2001-2003 model years.
The PC168 is a miniature wedge bulb in the T10 form factor, distinguished by a printed circuit board twist-lock socket rather than a conventional bayonet or wedge base.
The twist-lock socket of the PC168 is associated with instrument cluster applications, which reflects a fitment design oriented toward compact, low-clearance housings.
Despite both the 3157 and PC168 operating at 12V, their socket types are entirely different, and the two bulbs are not interchangeable with each other.
Both bulb types conform to ANSI standards shared between the United States and Canada, indicating consistent part availability across those markets.
The PC168 specification does not include a wattage rating, whereas the 3157 carries a dual-wattage rating of 27W/7W.
