Additional Notes

The Freightliner FL106 uses the 194 bulb for the roof marker position across all listed model years, spanning 1994-2003.
The 194 is a miniature wedge-type bulb, classified under the T10 designation, which refers to its tubular glass envelope size expressed in eighths of an inch.
The bulb operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of marker and clearance lighting applications.
The 194 bulb conforms to ANSI standards recognized in both the United States and Canada, meaning it meets a defined set of electrical and physical tolerances rather than being a proprietary specification.
The wedge base design of the 194 eliminates a separate metal base, as the glass envelope itself is pinched at the bottom to form the electrical contacts, which is a common construction method for marker light sockets.
The T10 wedge format is shared by several bulb numbers in the same family, including the 168 and 2825, though those variants differ in wattage and are not interchangeable without verifying socket and circuit compatibility.
