Chevrolet C60 Instrument Panel Bulb Size

Additional Notes

• The instrument panel bulb specifications for the Chevrolet C60 span the 1960-1988 model years, with five distinct ANSI-standard bulb types used across that period: the 168, 194, 57, 53, and 1895.
• The 1895 is a T5 miniature wedge bulb rated at 12V and 0.9W, making it the lowest-wattage type in these specifications. It appears in the 1962-1966, 1969-1971, 1975, and 1977 model years.
• The 168 and 194 are both T10 miniature wedge bulbs operating at 12V, though they differ in wattage. The 168 draws 4.9W while the 194 draws 3.78W. Despite sharing the same T10 form factor, these two bulb types are not rated identically and are not interchangeable without accounting for the wattage difference.
• The 168 is specified for the 1961, 1968, 1978, 1982, 1985-1986, and 1988 model years, while the 194 is specified for the 1964, 1967, 1972, 1974, 1979, 1983, and 1987 model years.
• The 53 and 57 both use a BA9s bayonet base and operate at 12V, but differ in wattage. The 53 is rated at 2W and the 57 at 1W. The shared base type means physical fitment may be possible between the two, but the wattage difference represents a meaningful electrical distinction.
• The 53 is specified for the 1960, 1973, 1976, 1980-1981 model years, while the 57 appears only in 1984, making it the least frequently specified bulb type across the full range.
• All five bulb types conform to ANSI standards recognized in both the United States and Canada, indicating consistent regulatory compliance across the entire specification range.
• The T5 and T10 designations refer to the tubular bulb envelope width in units of one-eighth of an inch, meaning a T5 bulb is 5/8 inch wide and a T10 is 10/8 inch wide. This physical size difference means T5 and T10 wedge bulbs are not interchangeable regardless of voltage or wattage compatibility.
