Additional Notes

The 194 bulb is the specified size for the Lexus IS500 glove box across the 2023-2024 model years.
The 194 designation follows the ANSI standard used in the United States and Canada, classifying it as a miniature wedge-base bulb in the T10 form factor.
The T10 wedge base is a push-in, pinless design where the glass envelope itself forms the electrical contact, seating directly into a corresponding socket without requiring a separate locking mechanism.
The 194 bulb operates at 12 volts with a power draw of 3.78 watts, consistent with low-current interior lighting applications.
The T10 socket type is widely shared across interior lighting positions in many vehicles, though fitment in a specific position such as the glove box depends on the physical space and socket orientation present in that application.
