Suzuki Motorcycle GSX-R750 Headlight Bulb Size

Additional Notes

• The 9003 bulb is the most widely used type across the Suzuki Motorcycle GSX-R750 headlight specifications, appearing in both high beam and low beam positions across the majority of model years covered. It is a dual-filament halogen bulb operating at 12V with a 60W high beam filament and a 55W low beam filament, fitted with a P43t base and built to the ANSI standard used in the US and Canada.
• The H7 bulb is the second most frequently listed type in these specifications, used in both high beam and low beam positions across several model years. It is a single-filament halogen bulb rated at 12V and 55W, using a PX26d base. It follows the ECE standard and carries approval for use in the US and Japan as well as Europe and worldwide markets.
• The H9 bulb serves as the high beam bulb for the GSX-R750 across the 2006-2007 and 2011-2019 model years. It is a single-filament halogen bulb rated at 12V and 65W, using a PGJ19-5 base. Though built to the ECE standard, it also holds US approval.
• The 9003 bulb functions as a dual-filament type, meaning a single bulb serves both the high beam and low beam functions within one housing. In contrast, model years specifying separate H9 or 9005 high beam bulbs and H7 or H11 low beam bulbs use a two-bulb headlight system with dedicated single-filament bulbs for each function.
• The 9005 bulb is listed exclusively for the high beam position on the 2008-2009 GSX-R750. It is a single-filament halogen bulb rated at 12V and 65W with a P20d base, following the ANSI standard. Those same years use the H11 for the low beam, making the 2008-2009 pairing the only one in these specifications to combine the 9005 and H11 types.
• The H9 and 9005 bulbs share the same 12V, 65W electrical rating, but they use physically different bases, PGJ19-5 and P20d respectively, making them non-interchangeable despite their identical wattage and voltage.
• The 9003 bulb, when listed for both the high beam and low beam positions in the same model year, indicates that a single bulb type handles both functions. This differs from years where the high beam and low beam positions each carry a distinct bulb type, requiring two separate bulbs for the headlight assembly.
• The H11 bulb appears only in the low beam position for the 2008-2009 model years. It is a single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base. Although it shares the same wattage as the H7, the two bulbs use different bases and are not interchangeable.
