Additional Notes

The H11 is the most frequently referenced bulb type in these specifications. It is a single-filament halogen bulb operating at 12 volts and 55 watts, built to the ECE standard used across Europe and worldwide, and also approved for use in the United States.
The H11 uses a PGJ19-2 base, a locking-tab connector design that physically distinguishes it from visually similar bulbs such as the H8 and H9, which share the same base family but differ in wattage and are not interchangeable without consequence.
For the Mazda CX-5, the front fog light takes an H11 bulb across the 2013-2015 model years without condition.
The 2016 Mazda CX-5 front fog light also uses the H11, but the specification applies specifically to vehicles equipped with halogen capsule headlamps, indicating that trim or package level is a relevant factor for that year.
