The Volkswagen Tiguan fog light utilizes 9006 and H8 bulb sizes for the front lighting assembly. Data for the specified vehicle covers the period from 2009 through 2022.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volkswagen Tiguan front fog light position uses two distinct bulb types across its model years: the 9006 and the H8, both single-filament halogen bulbs operating at 12 volts.
The 9006 bulb follows the ANSI standard, which governs bulb specifications in the United States and Canada. It draws 55 watts and uses a P22d base.
The H8 bulb follows the ECE standard, the regulatory framework used across Europe and much of the world. It draws 35 watts and uses a PGJ19-1 base, though it also carries approval for use in the United States.
Despite both the 9006 and H8 being single-filament halogen bulbs at 12 volts, their wattage and base types differ, making them physically and electrically non-interchangeable.
The Volkswagen Tiguan front fog light used the 9006 bulb from 2009-2017, with the exception of 2018-2021, when the H8 replaced it. The 9006 returned for the 2022 model year.
The H8 bulb, at 35 watts, draws notably less power than the 9006 at 55 watts, a difference relevant to the electrical load placed on the vehicle's fog light circuit.
The rear fog light position on the Volkswagen Tiguan uses the H21W bulb, an ECE-standard single-filament signalling bulb rated at 12 volts and 21 watts.
The H21W uses a BAY9s base, a bayonet-style fitting with offset pins. This base type is distinct from the bases used by both the 9006 and H8, and the three bulb types share no fitment compatibility.
The rear fog light specifications cover the 2012-2018 model years, all of which share the H21W bulb without variation.
The H21W is classified as a signalling bulb rather than an illumination bulb, reflecting its lower wattage and its role in rear visibility signalling rather than forward lighting.
