Additional Notes

The bulb size 37 is an ANSI-standardized type used in the United States and Canada, classified as a miniature wedge bulb with a T5 tubular envelope rating.
The T5 designation refers to the bulb's tubular shape, with the numeric value indicating a width of five-eighths of an inch.
The bulb size 37 operates at 12 volts and draws 1 watt, placing it among the lowest-power indicator bulbs in automotive applications.
The Hyundai Excel uses bulb size 37 for the high beam indicator across all documented model years from 1987-1994, reflecting an uninterrupted fitment consistency throughout the vehicle's production run in that period.
The miniature wedge base of the 37 bulb requires no separate socket retainer, as the wedge-shaped glass pinch at the base holds the bulb in place through friction contact with the housing.
