Additional Notes

The 1445 is the sole bulb type specified for the ash tray position across all listed model years of the Chevrolet Chevelle.
The 1445 bulb follows the ANSI standard, which is the recognized classification system for lamp types in the United States and Canada.
This bulb operates on a 12-volt electrical system, consistent with the standard automotive DC voltage used in passenger vehicles of this era.
At 2 watts, the 1445 is a low-output bulb, which is appropriate for a small interior illumination role such as an ash tray light.
The 1445 uses a BA9s base, a miniature bayonet-style fitting with a 9mm collar and a single locating pin, distinguishing it from double-contact bayonet bases used in other automotive applications.
The single-filament construction of the 1445 means it serves one lighting function only, with no secondary circuit for dimming or signaling.
The Chevrolet Chevelle used the 1445 bulb for the ash tray position consistently across the 1964-1973 model years covered in these specifications.
When sourcing a replacement, the BA9s base type is a fitment-critical detail, as bulbs with visually similar envelopes may carry incompatible bases such as the BA9 or BAX9s, which differ in pin configuration.
