Toyota MR2 Spyder Parking Light Bulb Size

Additional Notes

• The 168 bulb is the sole parking light bulb size listed for the Toyota MR2 Spyder across all six model years from 2000-2005, indicating a consistent fitment throughout the vehicle's production run in that period.
• The 168 bulb follows the ANSI standard recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across North American markets.
• This bulb uses a T10 miniature wedge base, a base type that relies on two angled metal contacts on either side of the glass envelope rather than a separate metal cap, allowing it to be inserted and removed without a socket twist.
• The 168 operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
• At 4.9 watts, the 168 draws relatively low power, a characteristic typical of parking light applications where the bulb is intended for visibility rather than primary illumination.
• The T10 wedge form factor is shared by several bulb numbers in the miniature wedge family, meaning physical fit alone does not confirm electrical compatibility. Wattage and voltage ratings must also match the original specification before substitution.
