Additional Notes

The 198 bulb is the brake bulb size for the Harley-Davidson FXDS-Conv Dyna Convertible across the 1994-1998 model years.
The 198 bulb follows the ANSI standard, which is the recognized specification system for miniature bulbs in the United States and Canada.
It belongs to the T5 form factor, a miniature wedge-base bulb type that uses a tapered plastic base inserted directly into a socket without a separate metal base or locking mechanism.
The 198 bulb operates at 12 volts, consistent with the standard electrical system voltage found in most production motorcycles.
At a rated output of 2 watts, the 198 is a low-wattage bulb, reflecting its role as a small indicator or auxiliary light rather than a primary illumination source.
The wedge-base design of the T5 type means fitment depends on socket compatibility with that specific base style, and substitution with bulbs using bayonet or screw bases would not be interchangeable.
