Additional Notes

The Freightliner MB Line uses the 198 bulb for its tail light across the 1995-1997 model years, specifically in the Cab Over Engine configuration.
The 198 bulb follows the ANSI standard, which governs bulb specifications across the United States and Canada, ensuring consistent performance and interchangeability within that standardized framework.
This bulb belongs to the T5 form factor, a miniature wedge type. The wedge base design means the bulb is held in place by the socket gripping the glass envelope directly, with no separate metal base or pins.
The 198 operates at 12 volts and draws 2 watts, placing it among the lower-output bulbs used in automotive lighting. At this wattage, it is suited to indicator or marker functions rather than high-intensity illumination.
The Cab Over Engine designation in the fitment data indicates that these specifications apply to that specific cab configuration of the MB Line, and fitment outside of that configuration is not supported by the provided data.
