The Toyota Solara brake light utilizes bulb size 2458 and bulb size 3157 for various lighting applications. Data for the specified components covers the range from 1999 through 2003.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Toyota Solara uses the 3157 bulb across its brake lighting positions for the 1999-2003 model years, making it the dominant bulb type in these specifications.
The 3157 is a dual-filament wedge bulb classified under the T25 body type, rated at 12V with a wattage split of 27W for the high-intensity filament and 7W for the low-intensity filament, conforming to ANSI standards for the US and Canada markets.
The dual-filament design of the 3157 allows a single bulb to serve both brake and tail light functions within the same housing, which is why it appears in combined brake positions.
The Center High Mount Stop Light on the Toyota Solara uses the 921 bulb across all listed model years, 1999-2003, a single-filament wedge bulb classified under the T15 body type, rated at 12V and 16W, also conforming to ANSI standards for the US and Canada.
The 921 and 3157 are not interchangeable despite both being wedge-base bulbs; the T15 and T25 designations indicate different physical sizes, and their wattage and filament configurations differ.
The 2003 Outer Brake position carries a production date qualifier of "To 12/2002," indicating that the 3157 fitment applies only to vehicles produced up to that date within the 2003 model year.
