Volkswagen Cabrio Headlight Bulb Size

Additional Notes

• The 9005 bulb is the most frequently specified high beam size across the Volkswagen Cabrio range, appearing in 2000-2002 as the sole high beam option and sharing fitment duties in 1995-1999 alongside other types. It is a single-filament halogen bulb operating at 12V and 65W with a P20d base, built to the ANSI standard used in the US and Canada.
• The 9004 bulb is a dual-filament halogen type rated at 12V, 65W for high beam and 45W for low beam, with a P29t base. Its dual-filament design means a single 9004 bulb handles both high and low beam functions within one housing, which differs from the single-filament 9005 and 9006 bulbs that each serve only one beam function.
• The 9003 bulb is a dual-filament halogen type rated at 12V, 60W high beam and 55W low beam, with a P43t base. On the 1999 Volkswagen Cabrio, it is specified exclusively for the 2-headlamp configuration, where it serves both beam functions simultaneously from a single bulb per side.
• The H7 bulb follows the ECE standard rather than the ANSI standard used by the 9005, 9006, 9004, and 9003 types. It is a single-filament halogen bulb with a PX26d base, rated at 12V and 55W, and carries approval for use in the US and Japan in addition to European and worldwide markets.
• On the 1999 Volkswagen Cabrio, the low beam specification splits into three distinct fitments depending on headlamp count and production timing: the 9003 for the 2-headlamp setup, the 9006 for the early 4-headlamp setup, and the H7 for the late 4-headlamp setup. These three bulbs are not interchangeable with one another due to differing base types and filament configurations.
• The 1996 and 1997-1998 model years each carry two separate high and low beam fitments, reflecting mid-production changes. The 1996 Cabrio uses a 9005 high beam and 9006 low beam for the early model, then shifts to a 9004 for both functions in the late model, which consolidates two bulbs into one dual-filament unit.
• The 9006 bulb is a single-filament halogen type rated at 12V and 55W with a P22d base, designated solely for low beam use. Although its wattage matches the H7, the two bulbs use different base types, P22d versus PX26d, making them physically incompatible despite sharing the same voltage and power rating.
• From 2000-2002, the Volkswagen Cabrio standardized on the 9005 for high beam and the H7 for low beam, representing a pairing of one ANSI-standard bulb and one ECE-standard bulb within the same headlamp assembly.
