The Suzuki Esteem brake light requires a 1157 bulb size for proper illumination and function. Data for the specified component covers the period from 1995 through 2002.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Esteem uses the 1157 bulb for its brake lights across all model years from 1995 to 2002, making it the most consistently specified bulb type in these brake lighting specifications.
The 1157 is a dual-filament bulb operating at 12V with a 21W/5W output, meaning one filament handles the brighter stop light function while the second, lower-wattage filament serves as a running or tail light.
The 1157 uses a BAY15d bayonet base, a two-pin offset bayonet mount designed to prevent incorrect single-filament bulbs from being seated in its place, which is a relevant fitment consideration during replacement.
The center high mount stop light (CHMSL) on the Suzuki Esteem transitioned from the 921 bulb to the 7440 bulb between the 1996 and 1997 model years, representing a specification change mid-production run.
The 921 bulb was specified for the CHMSL on the 1995-1996 Esteem. It is a single-filament wedge bulb in the T15 form factor, rated at 12V and 16W.
The 7440 bulb replaced the 921 for the CHMSL on the 1997-2002 Esteem. It is also a single-filament wedge bulb but uses the larger T20 form factor and carries a higher 21W rating.
The 7440 and 921 are not interchangeable. Although both are single-filament wedge bulbs, they differ in physical size and wattage, and substituting one for the other risks improper fitment or electrical incompatibility.
All three bulb types specified across these brake lighting positions conform to ANSI standards applicable in both the United States and Canada.
