Additional Notes

The Harley-Davidson FXDL Low Rider 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 a tubular glass envelope approximately 5/8 of an inch wide with a wedge-shaped base that seats directly into a socket without a separate metal base or locking pins.
The 198 bulb operates at 12 volts and draws 2 watts, placing it among the lower-wattage bulbs used in automotive applications, consistent with a parking light function rather than a primary illumination role.
The 198 designation follows ANSI standardization recognized in both the United States and Canada, meaning bulbs sold under this number from different manufacturers are expected to conform to the same electrical and physical specifications.
The wedge base design of the T5 form factor means fitment is determined by the physical size of the wedge itself, and substituting a bulb with a differently sized wedge base would result in an improper or failed connection even if the voltage and wattage ratings were otherwise compatible.
