Volkswagen Golf SportWagen high beam headlight bulbs use H9, D3S, or H15 sizes, while low beam headlight bulbs use H7 or D3S sizes depending on configuration. The replacement chart covers 2015 through 2019 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
ECE standard (Europe & worldwide). Mercury-free HID (xenon) discharge bulb with PK32d-5 base and integral ignitor, for projector-type housings. 42V, 35W.
The Volkswagen Golf SportWagen uses four distinct bulb types across its headlight positions: H9, H15, H7, and D3S. The H7 and D3S types appear in both high beam and low beam positions depending on the headlamp system fitted, while H9 and H15 are exclusive to the high beam position.
The D3S is a mercury-free HID (xenon) discharge bulb operating at 42V and 35W. It carries a PK32d-5 base with an integral ignitor and is designed specifically for projector-type housings. It is governed by ECE standards applicable in Europe and worldwide.
The H15 is a dual-filament halogen bulb rated at 12V with a 55W main filament and a 15W secondary filament, using a PGJ23t-1 base. Its dual-filament design means it serves a combined function within a single bulb unit, which is a notable fitment consideration when sourcing a replacement.
The H7 is a single-filament halogen bulb rated at 12V and 55W, using a PX26d base. Unlike some ECE-standard bulbs, the H7 holds approval in the US and Japan in addition to Europe and worldwide markets, reflecting broader regulatory acceptance.
The H9 is a single-filament halogen bulb rated at 12V and 65W, using a PGJ19-5 base. It is ECE-standard and also approved in the US. At 65W, it operates at a higher wattage than the H7, and the two bulbs use different base types, making them non-interchangeable despite both being single-filament halogen types.
For the 2015-2018 Golf SportWagen, the high beam headlight position accepts either a D3S or an H15 bulb, depending on whether the vehicle is fitted with HID or halogen capsule headlamps. These two systems are not interchangeable, as HID and halogen housings differ in design and electrical requirements.
The 2019 Golf SportWagen departs from the H15 used in prior model years, specifying an H9 for the high beam position in halogen capsule headlamp configurations. The H9 and H15 use different bases (PGJ19-5 versus PGJ23t-1) and wattage ratings, confirming they are not substitutes for one another.
Across all listed years, the low beam position for halogen capsule headlamp configurations consistently uses the H7 bulb. The HID-equipped variants use the D3S for low beam across the same span, with the D3S serving dual duty in both beam positions on HID-equipped vehicles.
