Additional Notes

The 168 bulb is the sole front side marker bulb type listed for the Toyota Corolla Cross across the 2022-2024 model years.
The 168 bulb follows the ANSI standard recognized in the United States and Canada, placing it within a defined regulatory framework for miniature automotive lighting.
It uses a T10 miniature wedge base, a capless form factor where the glass envelope itself is pressed into the socket, eliminating the need for a separate metal base or pins.
The electrical rating of 12V and 4.9W positions the 168 among low-wattage incandescent bulbs, consistent with side marker applications that require continuous illumination without significant heat output.
The T10 wedge format is shared by several bulb types across different ANSI designations, meaning physical fitment alone does not confirm electrical compatibility. Wattage and voltage ratings must match the socket specification before substitution.
