Additional Notes

The Ford Ranger instrument panel bulb specifications span model years 1983 to 2003, covering three distinct bulb sizes across that range: 161, 194, and 37.
The 194 bulb is the most frequently specified type across the Ford Ranger instrument panel data, appearing in 1983-1988, 1990-1992, 1994, 1996-1999, and 2001-2002.
The 194 is an ANSI-standard miniature wedge bulb rated at 12V and 3.78W, fitting a T10 wedge base, which is a common format in automotive instrument panel applications.
The 161 bulb appears in the Ford Ranger instrument panel for 1993, 1995, 2000, and 2003. Like the 194, it is an ANSI-standard T10 miniature wedge bulb, but it is rated at a lower 1W output.
Although the 161 and 194 share the same T10 wedge base form factor and both operate at 12V, their wattage ratings differ, with the 194 drawing approximately 3.78 times more power than the 161.
Because the 161 and 194 share a T10 wedge base, physical fitment between the two is possible, but substituting one for the other would result in a different light output level than the manufacturer specified for that model year.
The 1989 Ford Ranger instrument panel uses the bulb size 37, which is an ANSI-standard T5 miniature wedge bulb rated at 12V and 1W, making it physically incompatible with the T10 socket used in all other listed model years.
The T5 base of the 37 bulb is smaller than the T10 base of the 161 and 194 bulbs, meaning the 37 cannot be substituted with either of the other two types specified in this data set without a socket mismatch.
