Chevrolet C50 Instrument Panel Bulb Size

Additional Notes

• The instrument panel bulb specifications for the Chevrolet C50 span the 1960-1988 model years, covering five distinct ANSI-standard bulb types across that range.
• The 168 bulb is the most frequently specified type across the C50's instrument panel history, appearing in thirteen model years. It is a T10 miniature wedge bulb rated at 12V and 4.9W.
• The 1895 bulb is the second most common type in these specifications, used in nine model years. It is a T5 miniature wedge bulb rated at 12V and 0.9W, drawing notably less power than the 168.
• Although both the 168 and 194 share the T10 wedge form factor, their wattage ratings differ: the 168 draws 4.9W while the 194 draws 3.78W. The 194 is specified for the 1962 and 1982-1984 model years, and these two bulb types are not rated identically despite their physical similarities.
• The 53 and 57 bulbs both use a BA9s bayonet base rather than a wedge base, distinguishing them from the other three types in these specifications. The 53 is rated at 12V and 2W, while the 57 is rated at 12V and 1W.
• The 53 bulb appears in the 1960, 1972, 1976, and 1981 model years, and the 57 bulb is specified exclusively for the 1988 model year.
• All five bulb types in these specifications conform to ANSI standards recognized in both the United States and Canada, and all operate on a 12V electrical system.
• The instrument panel bulb specification for the C50 changed multiple times across consecutive model years, indicating that a single replacement type does not apply uniformly across the full production range.
