The Toyota Venza side marker requires a 194 bulb size for proper installation and function within the lighting assembly. Data for the specified component covers the range from 2023 to 2024.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Toyota Venza uses the 168 bulb for the front side marker position across the 2009-2012 model years, while the rear side marker position uses the 7443 bulb across the same span.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, conforming to ANSI standards applicable in both the United States and Canada.
The 7443 is a T20 dual-filament wedge bulb rated at 12V with a 21W/5W output, also conforming to ANSI standards for the US and Canadian markets.
The dual-filament construction of the 7443 means it contains two separate filaments within a single envelope, allowing it to serve two distinct brightness levels from one housing.
The T10 and T20 designations refer to the outer width of the bulb envelope, with T10 indicating a narrower profile than T20. These two bulb types are not interchangeable with each other.
The significant wattage difference between the 168 (4.9W) and the 7443 (21W/5W) reflects their respective roles, with the rear position drawing considerably more power to meet visibility requirements.
Both bulb types use a wedge base rather than a bayonet or screw base, meaning they are secured by friction fit within the socket rather than by a locking mechanism.
