Additional Notes

The T5 miniature wedge is the bulb type specified for the automatic transmission indicator in the Chevrolet Aveo across the 2009-2011 model years.
The T5 designation refers to the tubular glass envelope, with the number indicating a width of five-eighths of an inch.
Bulb number 37 operates at 12 volts and draws 1 watt, placing it among the lower-wattage bulbs used in instrument panel indicator applications.
The wedge base design means the bulb is held in its socket by the tension of the base contacts alone, with no separate metal bayonet or screw fitting involved.
Bulb number 37 carries ANSI standardization applicable to both the United States and Canada, meaning the specification conforms to a recognized North American industry standard.
The wedge base format is common in instrument cluster and indicator applications because it allows direct insertion and removal without rotating the bulb.
