Additional Notes

The 1895 bulb is the most frequently specified type across the Chevrolet Chevelle instrument panel fitments, appearing in the 1964-1966 and 1969 model years. It is an ANSI-standard miniature wedge bulb with a T5 form factor, rated at 12V and 0.9W, making it the lowest-wattage bulb among all types listed in these specifications.
The 1445 bulb is the second most common type, specified for the 1967-1968 and 1973 Chevrolet Chevelle. Unlike the wedge-base bulbs used in other years, the 1445 uses a BA9s bayonet-style base, which is a physically distinct socket type and is not interchangeable with wedge-base bulbs without a socket adapter.
The T10 wedge form factor is shared by both the 168 and 194 bulbs, specified for the 1972 and 1970 model years respectively. Although these two bulbs share the same physical base and housing profile, they differ in wattage: the 168 draws 4.9W while the 194 draws 3.78W. Substituting one for the other may affect illumination intensity and circuit load.
All four bulb types listed across these specifications are ANSI-standard bulbs recognized in both the United States and Canada, meaning they conform to a shared North American standardization rather than regional or proprietary specifications.
The 1895 and the T10-based 168 and 194 bulbs all use wedge-style bases, but the T5 form factor of the 1895 is narrower than the T10 form factor of the 168 and 194. These two wedge sizes are not physically interchangeable, as the socket width differs between T5 and T10 housings.
The 1973 model year returns to the 1445 BA9s-base bulb after the 1970 and 1972 model years used T10 wedge-base types, reflecting that no single bulb type was carried forward consistently across all years in these specifications.
