Additional Notes

The 198 bulb is the tail light bulb type specified for the Freightliner XB Line across the 1995-1997 model years.
The 198 bulb follows the ANSI standard, which is the recognized specification authority for lighting components in the United States and Canada.
This bulb uses a miniature wedge base, classified under the T5 designation. The T5 designation refers to a tubular bulb with a width of 5/8 inch, fitted with a wedge-style base that seats directly into a socket without a separate metal cap or pins.
The 198 bulb operates at 12 volts with a power draw of 2 watts, placing it among the lower-output bulbs used in automotive lighting applications.
