Additional Notes

The 194 bulb is the trunk bulb size for the Toyota GR Corolla across the 2023-2024 model years.
The 194 is a T10 miniature wedge bulb, which refers to its wedge-shaped base that holds the bulb in place without a separate socket or pins.
This bulb operates at 12 volts and draws 3.78 watts, placing it in the low-power range typical of interior and cargo lighting applications.
The 194 designation follows the ANSI standard, meaning the specification applies uniformly across the US and Canadian markets.
