The Suzuki XL-7 brake light components utilize 3057 and 7443 bulb sizes for the lighting systems. Data for the specified vehicle covers the period from 2002 through 2009.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki XL-7 brake lights use two distinct bulb types across its model years: the 3057 for 2007-2009 and the 7443 for 2002-2006.
Both the 3057 and 7443 are dual-filament wedge bulbs operating at 12V, with the higher-intensity filament handling the brake function and the lower-intensity filament serving as a running light.
The 3057 is a T25 wedge bulb rated at 27W/5W, making its brake filament notably more powerful than that of the 7443, which is a T20 wedge rated at 21W/5W.
Although the 3057 and 7443 share the same dual-filament wedge form and voltage, their physical sizes and wattage ratings differ, meaning they are not interchangeable between the 2002-2006 and 2007-2009 model years.
Both the 3057 and 7443 conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and photometric performance requirements.
The center high mount stop light (CHMSL) on the Suzuki XL-7 uses a different bulb from the main brake lights across all listed years.
For the 2002-2005 XL-7, the CHMSL uses the 921, a single-filament T15 wedge bulb rated at 12V and 16W, which is a lower-wattage unit compared to either brake bulb used in the same era.
The 2006 XL-7 CHMSL uses the 12961, a Philips part number rather than an ANSI-designated bulb, indicating it is sourced to a manufacturer-specific specification rather than a broadly standardized one.
The 12961 is a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W, making it a single-filament, low-wattage unit distinct from the 921 used in prior years.
The shift from the 921 to the 12961 for the 2006 CHMSL, alongside the change from 7443 to 3057 for the main brake lights in 2007, reflects that the XL-7 underwent fitment changes across its production run that affect bulb selection.
