Ford Aerostar Ash Tray Bulb Size

Additional Notes

• The Ford Aerostar ash tray bulb position uses one of two ANSI-standardized miniature wedge bulb types across its model years: the 1892 and the 1893.
• Both the 1892 and 1893 are T5 miniature wedge bulbs rated at 12 volts, making them compatible with standard 12-volt automotive electrical systems.
• The primary difference between the two bulb types is wattage. The 1892 is rated at 3 watts, while the 1893 is rated at 2 watts, meaning they are not interchangeable without a wattage mismatch.
• The T5 designation refers to the bulb's tubular envelope, which is 5/8 of an inch wide. The wedge base design eliminates the need for a separate socket, as the base itself forms the electrical contact.
• The Ford Aerostar uses the 1892 bulb for the ash tray across the majority of its production span, covering the 1986-1991 and 1994-1997 model years.
• The 1893 bulb applies specifically to the 1992-1993 model years, representing a lower-wattage fitment for those two years.
• Both bulb types carry ANSI standardization for the US and Canadian markets, indicating conformance to a defined set of performance and physical specifications recognized across those regions.
• Because the 1892 and 1893 share the same T5 wedge base form factor, physical installation is compatible between the two, but the wattage difference means substituting one for the other alters the electrical load on that circuit.
