Additional Notes

The Hyundai Scoupe uses the ANSI 37 bulb for the check engine light across all listed model years, spanning 1991-1995.
The 37 bulb is a T5 miniature wedge type, which refers to its tubular glass envelope with a width of 5/8 inch and a wedge-style base that connects directly without a separate metal socket pin.
This bulb operates at 12 volts and draws only 1 watt, placing it among the lowest-power bulbs used in automotive instrument panel applications.
The ANSI 37 designation confirms the bulb meets a standardized specification recognized in both the United States and Canada, meaning it is not a proprietary or region-specific part.
The wedge base design of the T5 37 bulb means it is held in place by tension from the socket walls rather than by a bayonet or screw mechanism, which is a common trait in instrument cluster and warning light applications.
Because the 37 bulb shares the T5 wedge form factor with several other ANSI-numbered bulbs, substitution with visually similar bulbs of different wattage or voltage ratings would result in incorrect electrical load for this circuit.
