Additional Notes

The Hyundai Elantra uses the ANSI 37 bulb for the seat belt warning light across the 1992-1995 model years.
The 37 bulb is a T5 miniature wedge type, which refers to its tubular glass envelope measuring 5/8 of an inch in width and its wedge-shaped base that connects directly into the socket without a separate metal base.
The 37 bulb operates at 12 volts and draws 1 watt, placing it among the lower-wattage bulbs used in automotive instrument and warning light applications.
The ANSI 37 designation indicates the bulb meets standardized specifications recognized in both the United States and Canada, meaning replacements sourced from either market are electrically and physically equivalent.
The wedge base design of the T5 bulb means the filament leads are bent along the sides of the glass to form the retention mechanism, eliminating the need for a separate bayonet or screw base.
Because all four listed model years share the same bulb size, a single replacement part number applies uniformly to the 1992-1995 Elantra seat belt warning circuit.
