The KTM 690 SMC uses a 9003 bulb size for both high beam and low beam headlight applications. This replacement chart covers vehicle production spanning 2008 to 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole headlight bulb type specified for the KTM 690 SMC across the 2008-2011 model years.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains both the high beam and low beam filaments within one glass envelope.
Because the 9003 serves both the high beam and low beam positions on the 690 SMC, both circuits draw from the same physical bulb.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W for the high beam filament and 55W for the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm collar, and this base type determines physical fitment into the headlight housing.
The 9003 is defined under the ANSI standard and is the designation used in the United States and Canada; it is electrically and mechanically equivalent to the H4 bulb used under European and international standards, though the designations differ by market.
The P43t base is not interchangeable with single-filament bases such as P14.5t or P15d, so substituting a single-filament bulb would not be compatible with the 690 SMC headlight housing.
