Additional Notes

The 194 bulb is the sole front side marker bulb size listed for the Toyota MR2 Spyder across the 2000-2005 model years, making it a consistent fitment throughout the entire production run covered by these specifications.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical requirements shared across North American markets.
This bulb uses a T10 miniature wedge base, a small single-contact base type that is retained by friction within its socket rather than by a bayonet or screw mechanism.
The 194 operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs found in automotive lighting applications, consistent with the limited illumination demands of a side marker position.
The T10 wedge format is shared by a number of other bulb types, which means physical fitment alone does not confirm electrical compatibility. Voltage and wattage ratings must also correspond to the socket's specifications before a substitute bulb is used.
