The Isuzu Oasis brake light requires a 7443 bulb size for proper installation and function within the lighting assembly. Data for the specified component covers the range from 1996 to 1999.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Isuzu Oasis uses the 7443 bulb for its brake lights across the full 1996-1999 model range.
The 7443 is a dual-filament wedge bulb classified under the T20 form factor, operating at 12V with a wattage rating of 21W on the high-intensity filament and 5W on the low-intensity filament.
The dual-filament design of the 7443 allows a single bulb to serve both the brake light and tail light functions within the same housing.
The 7443 is an ANSI-standardized bulb, meaning its specifications are consistent across products sold in the United States and Canada.
The Center High Mount Stop Light on the Isuzu Oasis uses the 168 bulb for the same 1996-1999 model range.
The 168 is a single-filament miniature wedge bulb classified under the T10 form factor, operating at 12V and rated at 4.9W.
The 168 is also an ANSI-standardized bulb, with uniform specifications across the US and Canadian markets.
The 7443 and 168 are not interchangeable. They differ in form factor, filament count, and wattage, and each is assigned to a distinct lighting position on the vehicle.
The T20 form factor of the 7443 is physically larger than the T10 form factor of the 168, which reflects the higher power demands of the primary brake light function compared to the center high mount stop light.
