Toyota Prius Ash Tray Bulb Size

Additional Notes

• The T5 miniature wedge bulb, designated ANSI type 74, is the specified ash tray bulb for the Toyota Prius across the 2001-2003 model years. It operates at 12 volts with a power draw of 1.4 watts.
• The T5 designation refers to the bulb's tubular envelope width, expressed in eighths of an inch, placing it among the smallest bulb forms used in automotive interior applications. The wedge base design relies on the glass envelope itself being pinched and inserted directly into a socket, with no separate metal base or pins.
• The ANSI type 74 rating indicates the bulb meets standardized North American specifications as defined for the United States and Canadian markets. This standardization means the bulb is produced by multiple manufacturers to identical electrical and physical tolerances.
• At 1.4 watts, the type 74 draws minimal current, which is consistent with its role in a low-priority interior illumination position such as an ash tray. The 12-volt rating aligns with the standard electrical system voltage of conventional passenger vehicles.
• The wedge base format of the type 74 is not universally interchangeable with other T5 bulbs that use different base types, such as the festoon or bayonet configurations, even when envelope size appears similar.
