Additional Notes

The 1889 bulb is the map light specification for the Sterling 827 across the 1989-1991 model years.
The 1889 is classified as a T5 miniature wedge bulb, where "T5" denotes a tubular glass envelope with a width of 5/8 of an inch.
The wedge base design means the bulb is held in place by the socket gripping the glass base directly, with no separate metal base or pins involved.
The 1889 operates at 12 volts and 2 watts, placing it among the lower-wattage miniature bulbs used in interior lighting applications.
The 1889 carries ANSI standardization for the United States and Canada, meaning its physical and electrical characteristics conform to a defined industry specification rather than a proprietary standard.
