The Yamaha XV1700 Road Star uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2004 through 2009 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 Yamaha XV1700 Road Star uses the 9003 bulb size across both high beam and low beam headlight positions for the 2004-2009 model years.
The 9003 is an ANSI-standard bulb designation recognized in the United States and Canada, making it the North American equivalent of the internationally designated H4 bulb.
As a dual-filament halogen bulb, the 9003 houses two separate tungsten filaments within a single glass envelope, one dedicated to high beam output and one to low beam output.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a three-pronged bayonet-style mount with a 43mm collar, a physical characteristic that determines socket compatibility.
Because both the high beam and low beam headlight positions on the XV1700 Road Star share the same 9003 specification, a single bulb type serves the entire headlight assembly rather than requiring separate bulbs for each function.
The H4 and 9003 designations refer to the same bulb type, with H4 being the ECE standard used in most markets outside North America and 9003 being the ANSI designation; the two are generally interchangeable in practice.
The P43t base is not compatible with sockets designed for single-filament bulbs such as the 9005 or 9006, and substituting those types would require a different socket or adapter.
