Additional Notes

The Toyota Van uses the 194 bulb for its parking lights across the 1986-1989 model years.
The 194 is classified as a miniature wedge bulb, designated T10 in the international bulb sizing system, where "T" refers to the tubular shape and "10" indicates the width in eighths of an inch.
The 194 operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of parking and marker light applications.
The 194 conforms to ANSI standards as recognized in both the United States and Canada, meaning it meets a defined set of electrical and physical specifications shared across those markets.
The wedge base design of the 194 requires no separate metal base or bayonet pins; the glass envelope itself acts as the retaining element when inserted into a compatible socket.
Because the 194 is an ANSI-standardized type, it is produced by multiple manufacturers and is widely interchangeable at the bulb level, provided the replacement unit carries the same 194 designation.
