Additional Notes

The bulb size 53 is an ANSI-standard type recognized in both the United States and Canada, operating at 12 volts with a 2-watt power draw and a single filament.
The 53 bulb uses a BA9s base, which is a miniature bayonet cap with a 9mm body width, commonly found in low-intensity interior lighting applications.
The Chevrolet Del Ray uses the 53 bulb for the ash tray across the 1957-1958 model years.
The single-filament design of the 53 bulb reflects its role as a simple indicator or courtesy light source, with no switching between brightness levels.
The BA9s base type is not interchangeable with other common miniature bases such as the wedge or festoon styles, making base compatibility a relevant factor when sourcing a replacement.
