Additional Notes

The Scion tC uses the ANSI 74 bulb for the ash tray across the 2005-2010 model years.
The 74 is classified as a miniature wedge bulb, corresponding to the T5 designation, which refers to a tubular bulb with a 5/8-inch body width.
The 74 bulb operates at 12 volts and draws 1.4 watts, placing it among the lowest-wattage bulbs found in automotive interior applications.
The wedge base design means the bulb is held in place by tension from the socket contacts rather than a bayonet or screw mechanism, making it tool-free to remove in most applications.
The 74 bulb is an ANSI-standardized type recognized in both the United States and Canada, meaning fitment follows a consistent specification across North American markets.
The T5 form factor is shared by several ANSI bulb numbers, so substitution with other T5-bodied bulbs requires confirming that voltage and wattage ratings match the 74 specification before use.
