Additional Notes

The Chevrolet Del Ray uses the 53 bulb for its ignition across both listed model years, 1957-1958.
The 53 bulb follows the ANSI standard, which is the recognized classification system for bulbs in the United States and Canada.
It operates on a 12-volt electrical system and draws 2 watts, placing it in the low-wattage range typical of indicator and instrument panel applications.
The 53 bulb uses a BA9s base, a miniature bayonet fitting with a 9mm cap and a single pin, which physically locks the bulb into its socket with a push-and-twist motion.
As a single-filament bulb, the 53 produces one fixed level of output with no dimming or dual-intensity function.
