Additional Notes

The Harley-Davidson FXDWG Dyna Wide Glide uses the 198 bulb for its parking light across the 1993-1998 model years.
The 198 is classified as a T5 miniature wedge bulb, a form factor defined by its tubular glass envelope with a wedge-shaped base that seats directly into a socket without a separate metal base or pins.
The bulb operates at 12 volts and draws 2 watts, placing it among the lower-wattage miniature bulbs used in automotive and motorcycle lighting applications.
The 198 carries ANSI standardization, meaning its physical and electrical characteristics conform to a defined specification recognized across the United States and Canada.
The wedge base design of the T5 form factor means fitment depends on socket compatibility with that specific base type; bulbs sharing the same wattage but using a different base style are not interchangeable.
