The Aprilia Tuono 50 uses a 6235B bulb size for both high beam and low beam headlight applications. The replacement chart covers 2004 to 2005 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 6235B is the bulb type used in both the high beam and low beam headlight positions of the Aprilia Tuono 50 across the 2004-2005 model years.
The 6235B is classified as a festoon bulb, meaning it is cylindrical in shape with contact caps at each end rather than a screw or bayonet base.
The 6235B operates on a 12V electrical system, which is standard for small-displacement motorcycle applications.
The glass envelope of the 6235B carries a blue tint, distinguishing it from clear festoon bulbs of otherwise similar construction.
The 6235B is designated as a specialty application bulb under the ANSI standard, indicating it is not a general-purpose replacement type.
The ANSI classification of the 6235B applies specifically to the US and Canadian markets.
Because the same bulb type serves both the high beam and low beam positions on the Tuono 50, the two circuits share identical fitment requirements rather than using separate bulb types for each function.
