Additional Notes

The Chevrolet Caprice glove box uses two distinct bulb form factors across its model years: the T5 miniature wedge and the T10 miniature wedge. The T5 is a smaller tubular wedge type, while the T10 is a slightly larger wedge format.
The T5 wedge type is the most frequently specified bulb form factor for the Caprice glove box, appearing across model years 1966-1982 and 1983-1992 under three different ANSI part numbers.
The 1891 bulb is an ANSI-standard T5 miniature wedge rated at 12V and 2W. It is the glove box bulb for the Chevrolet Caprice from 1980-1992.
The 1893 bulb is also an ANSI-standard T5 miniature wedge rated at 12V and 2W, sharing the same wattage as the 1891. It serves the 1974-1978 Caprice glove box. Despite identical voltage and wattage ratings, the 1891 and 1893 carry different ANSI designations and are not confirmed as interchangeable by these specifications.
The 1895 bulb is an ANSI-standard T5 miniature wedge rated at 12V and 0.9W, making it the lowest-wattage T5 variant in these specifications. It is specified for the Caprice glove box in 1966-1970, 1972-1973, and 1979.
The 194 bulb is an ANSI-standard T10 miniature wedge rated at 12V and 3.78W. It appears only for the 1971 Caprice glove box, making it an isolated fitment within the broader T5-dominant era of that period.
The 12961 is a Philips-branded T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It is the specified glove box bulb for the Chevrolet Caprice from 2014-2017 and carries the highest wattage of any bulb in these specifications.
The W2.1x9.5d base designation on the 12961 refers to a specific wedge base standard used in European and international bulb classifications, distinguishing it from the ANSI-numbered bulbs specified for earlier Caprice model years.
All bulbs across these specifications operate at 12V, which is consistent with standard automotive electrical systems. Wattage varies from 0.9W to 5W depending on the specific bulb type and model year.
Substituting one ANSI-numbered bulb for another, such as replacing a 1895 with a 1891 or 1893, is not supported by these specifications, as each year carries a distinct part number assignment regardless of shared physical form factors.
