Additional Notes

The Freightliner FS65 uses the 1895 bulb for parking lights across the 1996-2008 model years, with the sole exception of the 1997 Cab Over Engine configuration, which takes the 198 bulb instead.
Both the 1895 and 198 are ANSI-standardized miniature wedge bulbs sharing the T5 form factor and a 12-volt operating voltage, making them physically similar but electrically distinct.
The key electrical difference between the two bulbs is wattage: the 1895 is rated at 0.9W, while the 198 is rated at 2W, meaning the two are not interchangeable despite their shared T5 wedge base.
The T5 wedge base is a pinless design in which the glass envelope itself acts as the retention mechanism when inserted into the socket, a common construction in low-wattage automotive parking light applications.
The 1997 FS65 Cab Over Engine configuration is the only model year in the specification set that calls for the higher-wattage 198 bulb, while the 1996 Cab Over Engine configuration uses the standard 1895.
