The Bugatti Veyron 16.4 uses an H7 bulb size for high beam headlights and a D2S bulb size for low beam headlights. The replacement chart covers vehicle production years spanning 2006 to 2012 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.
The Bugatti Veyron 16.4 uses the H7 bulb for high beam headlights across all listed model years, 2006-2012.
The H7 is a single-filament halogen bulb rated at 12V and 55W, fitted with a PX26d base, and certified under ECE standards with approval also extended to the United States and Japan.
The Bugatti Veyron 16.4 uses the D2S bulb for low beam headlights across all listed model years, 2006-2012.
The D2S is a high-intensity discharge xenon bulb rated at 85V and 35W, fitted with a P32d-2 base, and designed specifically for projector-type housings.
Unlike the self-contained H7 halogen bulb, the D2S requires an external ignitor to initiate and sustain the arc discharge that produces light.
The H7 and D2S bulbs carry different base types, PX26d and P32d-2 respectively, making them physically incompatible with each other's sockets.
The split between a halogen high beam and a xenon low beam reflects a common fitment arrangement in which the two functions are served by distinct optical and electrical systems.
Both the H7 and D2S are certified under ECE regulations, indicating compliance with European and international photometric and safety standards.
