Lexus RC300 Glove Box Bulb Size

Additional Notes

• The 194 bulb is the sole glove box bulb type listed across all model years of the Lexus RC300 covered in these specifications (2021-2024).
• 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 acts as the retention mechanism within the socket.
• 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 many interior lighting positions in various vehicles, though fitment in a specific socket does not guarantee interchangeability with other positions in the same vehicle.
