Additional Notes

The 921 bulb is the cornering bulb size for the Toyota Tacoma across the 2021-2023 model years.
The 921 follows the ANSI standard, which is the classification system used in the United States and Canada for automotive lighting components.
It is a wedge-type bulb, designated T15, where the T indicates a tubular glass envelope and the 15 refers to the width in eighths of an inch.
The 921 operates at 12 volts and draws 16 watts, placing it in the low-wattage range typical of auxiliary lighting functions such as cornering lamps.
The wedge base design means the bulb is held in its socket by the tension of the base contacts rather than by a bayonet or screw mechanism, which affects how it is seated and removed.
