Additional Notes

The Honda CRX ash tray bulb specification calls for a type 74 across the 1988-1991 model years.
The type 74 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts and drawing 1.4 watts.
The T5 designation refers to the bulb's tubular envelope, with the numeral indicating a width of 5/8 inch expressed in eighths of an inch, making it a notably small form factor suited to interior illumination tasks such as ash tray lighting.
The miniature wedge base on the type 74 means the bulb is retained by the tension of the socket itself rather than by a separate bayonet or screw mechanism, a common construction in low-wattage automotive interior applications.
At 1.4 watts, the type 74 draws minimal current, which is consistent with its role as a small courtesy or indicator light rather than a primary illumination source.
Because the type 74 is an ANSI-standardized part, it is produced by multiple manufacturers to a common specification, meaning physical and electrical interchangeability exists among compliant units bearing that designation.
