Additional Notes

The Hyundai Sonata seat belt warning bulb is the type 37 across all listed model years, spanning 1989-2001.
The type 37 bulb follows the ANSI standard, which is the recognized specification framework used in the United States and Canada for miniature automotive bulbs.
This bulb belongs to the T5 form factor, a miniature wedge-base design commonly used in instrument panel and warning indicator applications where space is limited.
The type 37 operates at 12 volts and draws 1 watt, placing it among the lowest-power bulbs used in automotive warning systems.
The wedge base of the T5 type 37 is retained by friction rather than a bayonet or screw mechanism, meaning it is seated and removed by direct insertion and extraction without rotation.
Because the type 37 specification remained unchanged across the entire 1989-2001 range for the Sonata seat belt warning position, bulbs sourced for any year within that span are interchangeable with one another in this application.
