The Isuzu i-290 brake light requires a 3057 bulb size for the specific lighting component located at the rear of the vehicle. Available data for the specified model covers the range from 2007 to 2008.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Isuzu i-290 uses the 3057 bulb for its brake lights across the 2007-2008 model years.
The 3057 is a dual-filament wedge bulb classified under the T25 form factor, operating at 12V with a wattage split of 27W for the high-intensity filament and 7W for the low-intensity filament, making it suitable for combined stop and tail light functions.
The 3057 conforms to ANSI standards recognized in both the United States and Canada.
The center high mount stop light on the Isuzu i-290 uses the 912 bulb across the 2007-2008 model years.
The 912 is a single-filament wedge bulb classified under the T15 form factor, operating at 12V and 12W.
The 912 is a variant of the 921 bulb, meaning the two share the same physical T15 wedge base, though they differ in wattage output.
The 912 also conforms to ANSI standards recognized in both the United States and Canada.
The T25 and T15 designations refer to the outer envelope width of each bulb, with T25 indicating a wider body than the T15, and the two are not interchangeable with each other.
The dual-filament design of the 3057 distinguishes it functionally from the single-filament 912, as each filament in the 3057 serves a separate lighting circuit.
