Additional Notes

The H11 is a single-filament halogen bulb operating at 12 volts and 55 watts, built to the ECE standard recognized across Europe and worldwide, with approval also extended to the United States market.
The H11 uses a PGJ19-2 base, a proprietary locking connector that is not interchangeable with other common halogen bases such as H8 or H9, even though those bulbs share a physically similar housing profile.
The Toyota Yaris iA specifies the H11 bulb for the front fog light position across the 2017-2018 model years.
