Chevrolet Corvette Ash Tray Bulb Size

Additional Notes

• The 1445 and 53 bulbs share identical electrical ratings of 12V and 2W, and both use a BA9s base, making them the dominant bulb types across the Chevrolet Corvette ash tray specifications from 1955 through 1984.
• The BA9s base is a miniature bayonet-style cap with a 9mm body, commonly used in small indicator and courtesy lighting applications where low power draw is a priority.
• The 51 bulb, specified for the 1953-1954 Corvette, uses a BA15s single-contact bayonet base rather than the BA9s base found on the 53 and 1445 bulbs, making it physically incompatible with the sockets used in later model years.
• All three bulb types, the 1445, 53, and 51, are rated at 12V and 2W, confirming a consistent low-wattage design across the entire range of ash tray lighting in these specifications.
• The 1445 bulb is specified for the 1964-1976 and 1984 Corvette, representing the widest span of any single bulb type in these specifications.
• The 53 bulb is specified for the 1955-1963 Corvette, and while it shares the same base type and electrical ratings as the 1445, the two are distinct ANSI part numbers and are not guaranteed to be interchangeable without confirming physical fit.
• All three bulb types carry ANSI standard designations applicable to both the United States and Canada, indicating standardized production specifications rather than regional variants.
• The single-filament construction of all three bulb types is consistent with a simple on/off illumination function, as ash tray lighting does not require variable brightness or dual-intensity operation.
