The KTM 690 Supermoto uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2007 to 2008 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 9003 is a dual-filament halogen bulb operating at 12 volts, with a 60-watt filament for high beam and a 55-watt filament for low beam, mounted on a P43t base.
The ANSI 9003 designation applies to the United States and Canada market standard, making it the North American equivalent of the internationally designated H4 bulb, which shares the same electrical and physical characteristics.
The KTM 690 Supermoto uses the 9003 bulb for both high beam and low beam headlight positions across the 2007-2008 model years.
Because the 9003 carries both filaments within a single bulb, one unit serves the full headlight function rather than requiring separate bulbs for each beam mode.
The P43t base is a bayonet-style fitting with a 43mm collar, and correct base alignment is critical during installation since the dual-filament design requires precise positioning to maintain proper beam projection.
The shared 9003 fitment across both headlight positions on the 690 Supermoto means a single bulb type covers the entire headlight assembly, though each socket remains a distinct circuit.
