Additional Notes

The 194 bulb is the sole glove box bulb type listed across all Lexus RC F model years in these specifications, covering 2021 and 2023-2024.
The 194 designation follows the ANSI standard used in the United States and Canada, classifying it as a miniature wedge bulb in the T10 form factor.
The T10 wedge base is a push-in, pinless design that seats directly into a wedge-style socket, which is a common fitment method for interior lighting applications.
The 194 bulb operates at 12 volts with a power draw of 3.78 watts, consistent with low-current interior illumination use.
The T10 socket type is shared across a wide range of vehicle makes and models, though fitment into a specific housing depends on socket depth and retention clip design, not bulb type alone.
