Additional Notes

The Ford Windstar uses the 168 bulb for the license plate position across all model years listed, spanning 1995-2003.
The 168 bulb is classified as a miniature wedge type, designated T10 in the international bulb sizing system, where "T" refers to the tubular glass envelope shape and "10" indicates the width in eighths of an inch.
The wedge base design means the 168 bulb has no metal contact pins; instead, the glass envelope itself acts as the base, with wire leads folded against the sides to make electrical contact when inserted into the socket.
The 168 bulb operates at 12 volts and draws 4.9 watts, placing it among the lower-wattage bulbs in the T10 wedge family, which also includes the closely related 194 (3.78W) and 161 (3.0W) types.
The 168 bulb conforms to ANSI standards recognized in both the United States and Canada, indicating a standardized physical and electrical specification shared across many vehicle manufacturers in North American markets.
Because the T10 wedge family contains multiple bulbs with identical physical bases but different wattage ratings, substituting a higher-wattage T10 variant in place of the 168 could exceed the socket's designed thermal and electrical tolerances in the Ford Windstar license plate housing.
