Chevrolet B60 Instrument Panel Bulb Size

Additional Notes

• The Chevrolet B60 instrument panel bulb specifications span the 1980-1991 model years, with six distinct bulb types used across that period: 1895, 53, 168, 194, 57, and 1445.
• The 194 bulb is the most frequently recurring type in these specifications, appearing in the 1982-1983 and 1986 model years. It is a T10 miniature wedge bulb rated at 12V and 3.78W, compliant with ANSI standards for the US and Canada.
• The 1895 bulb covers the 1989-1991 model years, making it the only type used across three consecutive years in this dataset. It is a T5 miniature wedge bulb rated at 12V and 0.9W, the lowest wattage among all bulb types listed.
• The 53 bulb appears in the 1980-1981 and 1988 model years. It uses a BA9s bayonet base rather than a wedge base and is rated at 12V and 2W. The BA9s base is a small single-contact bayonet fitting, which is physically distinct from wedge-type bases and not interchangeable with them.
• The 168 bulb, used in the 1987 model year, shares the T10 wedge form factor with the 194 bulb but operates at a higher wattage of 4.9W. Despite the shared base type, the wattage difference means the two are not direct substitutes in applications where power draw is a factor.
• The 1445 bulb, specified for the 1984 model year, shares the BA9s base and 12V, 2W rating with the 53 bulb. However, the two carry different ANSI designations, and fitment interchangeability between them would depend on physical housing tolerances beyond the base type alone.
• The 57 bulb, used in the 1985 model year, also carries a BA9s base but is rated at only 1W, distinguishing it from both the 53 and 1445 bulbs despite the shared base configuration.
• All six bulb types in these specifications are ANSI-standardized for the US and Canadian markets and operate on a 12V system, consistent with standard automotive electrical architecture of that era.
