Additional Notes

The Hyundai Excel uses the ANSI 37 bulb for the seat belt warning light across all listed model years, spanning 1987-1994.
The 37 bulb is a miniature wedge type, classified under the T5 designation, which refers to a tubular glass envelope with a width of 5/8 of an inch.
The wedge base design means the bulb is held in place by the socket gripping the base of the glass itself, with no separate metal base or pins involved.
The 37 bulb operates at 12 volts and draws 1 watt, placing it among the lower-output bulbs used in instrument and warning light applications.
The ANSI 37 designation is recognized across both the United States and Canada, indicating standardized physical and electrical characteristics within those markets.
At 1 watt, the bulb produces minimal heat output, which is consistent with its role as a low-duty indicator light rather than an illumination source.
The T5 wedge form factor is widely used in dashboard and warning light sockets, though fitment still depends on socket compatibility specific to the application.
