Ford Ranger Glove Box Bulb Size

Additional Notes

• The Ford Ranger glove box uses the 194 bulb across the 1989-2004 and 2008-2011 model years, making it the more widely used of the two bulb types found in these specifications.
• The 194 is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12 volts and 3.78 watts.
• The T10 wedge base is a push-in connector type with no separate socket pins, relying on two angled metal tabs on the base to make electrical contact within the housing.
• The 1891 bulb is specified for the Ford Ranger glove box across the 1983-1988 model years.
• The 1891 is an ANSI-standard miniature wedge bulb in the T5 form factor, rated at 12 volts and 2 watts, drawing notably less power than the 194.
• The T5 wedge base follows the same general wedge-style contact design as the T10 but is physically smaller, meaning the 194 and 1891 are not interchangeable despite sharing the same base style.
• Both the 194 and 1891 are classified under ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances for each type.
• The shift from the 1891 to the 194 between the 1988 and 1989 model years represents a change in both bulb size and wattage for the glove box position.
