Additional Notes

The 893 bulb is the sole fog light bulb type listed for the Ford Aerostar across the 1993-1997 model years, appearing in the front fog light position throughout that entire span.
The 893 is a single-filament halogen bulb, meaning it serves one lighting function only and contains a tungsten filament enclosed within a halogen gas-filled envelope, which allows for a higher operating temperature and greater luminous efficiency compared to standard incandescent bulbs.
The bulb operates at 12 volts and draws 37.5 watts, placing it in a relatively low-wattage category for halogen fog lighting applications.
The 893 uses a PGJ19 base, a prefocus-type connector designed to seat the bulb at a fixed focal point within the reflector housing, which is critical for maintaining the precise beam pattern required in fog light applications.
The 893 conforms to ANSI standards as recognized in both the United States and Canada, indicating it meets a defined set of electrical and photometric performance criteria applicable across North American markets.
Because the same bulb size is specified across all five listed model years without variation, the front fog light housing design of the Ford Aerostar (1993-1997) is consistent with a single, unchanged bulb fitment throughout that production period.
The PGJ19 base is not universally interchangeable with other prefocus base types such as PG18 or PGJ13, and substituting a bulb with a different base type would result in incorrect fitment within the housing.
