The Isuzu Rodeo Sport brake light requires a 1157 bulb size for proper installation and function within the rear lighting assembly. Data for the specified component covers the period from 2001 through 2003.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Isuzu Rodeo Sport uses the 1157 bulb for brake lighting across the 2001-2003 model years.
The 1157 is a dual-filament bulb, meaning it serves two independent lighting functions within a single housing, typically stop and tail lighting.
It operates on a BAY15d bayonet base, a two-pin offset base design that prevents incorrect insertion by ensuring only one rotational orientation fits the socket.
The 1157 runs at 12V with a wattage rating of 21W on the high-filament circuit and 5W on the low-filament circuit.
The center high mount stop light on the Isuzu Rodeo Sport uses the 168 bulb across the same 2001-2003 model years.
The 168 is a miniature wedge bulb in the T10 form factor, which uses a wedge-shaped base rather than a bayonet or screw fitting, held in place by the socket's spring tension alone.
The 168 operates at 12V with a rated output of 4.9W, reflecting its role as a low-intensity indicator rather than a primary brake light source.
Both the 1157 and 168 conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances across compliant manufacturers.
The 1157 and 168 are not interchangeable with each other, as they differ in base type, filament count, wattage, and physical form factor.
