Victory Vegas Headlight Bulb Size

Additional Notes

• The 9003 bulb, used in the Victory Vegas for the 2016-2017 model years across both high and low beam positions, is a dual-filament halogen type operating at 12V with a 60W high beam filament and a 55W low beam filament. Its P43t base is an ANSI-standardized fitting recognized in the United States and Canada. Because it carries both filaments in a single unit, one bulb serves both beam functions simultaneously.
• The H11 bulb appears across the widest range of model years in these specifications, covering high beam fitment from 2009-2012 and low beam fitment from 2003-2012, with conditional low beam use also noted from 2005-2009 on halogen capsule headlamp configurations. It is a single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base under the ECE standard, and is also approved for use in the United States.
• The H8 bulb is specified for the high beam position on the Victory Vegas from 2003-2006. Although it shares the same ECE halogen family as the H11 and uses a visually similar PGJ19-1 base, it operates at a notably lower wattage of 35W at 12V. The PGJ19-1 and PGJ19-2 bases are not interchangeable, making substitution between H8 and H11 physically incompatible despite their similar appearance.
• The H7 bulb is listed for the high beam position in 2007-2008. It is a single-filament halogen bulb rated at 12V and 55W, using a PX26d base. The PX26d base differs from both the PGJ19-1 and PGJ19-2 bases used by the H8 and H11 respectively, meaning H7 units are not interchangeable with those types.
• The D1R bulb is specified for the low beam position on Vegas models equipped with HID headlamps from 2004-2009. It is a high-intensity discharge xenon bulb operating at 85V and 35W, with an integral ignitor built into the unit and a PK32d-3 base designed specifically for reflector-type housings. The "R" designation in D1R indicates reflector housing compatibility, distinguishing it from the D1S variant intended for projector housings.
• For the 2004-2009 model years, the Victory Vegas low beam position carried two distinct bulb specifications depending on headlamp type. Units fitted with HID headlamps required the D1R, while those fitted with halogen capsule headlamps required the H11. These two bulb types are electrically and physically incompatible, as the D1R operates at 85V through a discharge ignition system while the H11 operates at 12V through a standard halogen circuit.
• The high beam circuit on the Vegas used three different bulb types across the full production span covered by these specifications: H8 from 2003-2006, H7 in 2007-2008, H11 from 2009-2012, and 9003 in 2016-2017. Each of these types uses a distinct base fitting, so none are directly interchangeable with one another without modification to the socket or housing.
• The 9003 bulb used in 2016-2017 is the only dual-filament type in these specifications. All other halogen bulbs listed, including the H11, H7, and H8, are single-filament types. The D1R is also a single-output discharge unit. This distinction is relevant to fitment, as dual-filament sockets are wired differently from single-filament sockets and the two configurations are not cross-compatible.
