Additional Notes

The 1893 is the specified radio display bulb for the Ford Ranger across the 1983-1987 model years.
The 1893 bulb follows the ANSI standard, meaning it conforms to a recognized North American specification used in both the United States and Canada.
It is a T5 miniature wedge bulb, a form factor defined by a tubular glass envelope roughly 5/8 of an inch wide with a wedge-shaped base that seats directly into a socket without a separate metal base or pins.
The wedge base design means the bulb is held in place by the socket walls themselves, making it interchangeable only with sockets designed specifically for that base type.
The 1893 operates at 12 volts, which is consistent with standard automotive electrical systems.
At 2 watts, the 1893 draws very low current, a characteristic typical of instrument and display illumination bulbs rather than exterior lighting.
The T5 wedge form factor is a widely used category, though not all T5 wedge bulbs share identical voltage and wattage ratings, so substitutions require matching all three specifications to avoid socket damage or premature failure.
