Suzuki Motorcycle DL1000 V-Strom headlight bulbs utilize H9 and 9003 sizes for high beam operation and H7 and 9003 sizes for low beam operation. The replacement chart covers 2002 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.
The Suzuki Motorcycle DL1000 V-Strom uses three distinct halogen bulb types across its headlight system: the H9, the H7, and the 9003, each carrying different base fittings and filament configurations that make them mutually incompatible despite sharing the same 12-volt operating voltage.
The 9003 is an ANSI-standard dual-filament bulb rated at 12V with a 60W high beam and 55W low beam output, housed in a P43t base. Its dual-filament design means a single bulb serves both beam functions within one housing unit.
The H9 is an ECE-standard single-filament halogen bulb rated at 12V, 65W, fitted with a PGJ19-5 base. It carries approval for use in the United States in addition to European and worldwide markets.
The H7 is an ECE-standard single-filament halogen bulb rated at 12V, 55W, using a PX26d base. It holds approval across European, US, and Japanese markets.
On the Suzuki Motorcycle DL1000 V-Strom, model years 2002-2012 use the 9003 bulb for both the high beam and low beam headlight positions, reflecting the dual-filament nature of that bulb type.
From 2014 onward, the DL1000 V-Strom separates its high and low beam functions into distinct single-filament bulbs, with the H9 assigned to the high beam and the H7 to the low beam across the 2014-2019 model years.
The base fittings across the three bulb types are entirely different: PGJ19-5 for the H9, PX26d for the H7, and P43t for the 9003. This means none of these bulbs are physically interchangeable with one another.
The shift from the 9003 to separate H9 and H7 bulbs between the 2012 and 2014 model years represents a change from a single dual-filament unit per housing to two independent single-filament bulbs handling dedicated beam functions.
