Toyota Venza inner tail light uses a 194 bulb size while the outer tail light requires a 7443 bulb size for proper illumination. The replacement chart covers 2009 through 2012 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 Toyota Venza uses two distinct bulb types across its tail light system for the 2009-2012 model years: the 194 for the inner tail light position and the 7443 for the outer tail light position.
The 194 bulb is an ANSI-standard miniature wedge type with a T10 form factor, rated at 12V and 3.78W. Its low wattage reflects its role as an indicator or marker light rather than a primary stop or turn signal source.
The 7443 is an ANSI-standard dual-filament wedge bulb with a T20 form factor, rated at 12V with a 21W/5W output. The dual-filament design allows a single bulb to serve two functions, typically combining a brighter stop or turn signal filament with a dimmer running light filament.
The T10 and T20 designations refer to the tubular glass envelope width of the respective bulbs, with T10 being narrower than T20. These two types are physically incompatible with each other's sockets due to differing wedge base sizes.
Both the 194 and 7443 conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances within those markets.
The 194 bulb specification remains consistent across all four model years in the inner tail light position, and the 7443 specification remains consistent across all four model years in the outer tail light position, with no variation by year within the listed range.
Because the 7443 is a dual-filament bulb and the 194 is a single-filament bulb, the two are not interchangeable, and substituting one for the other would result in either electrical incompatibility or loss of a required lighting function.
