The Honda S2000 brake light utilizes a 7443 bulb size for the specific lighting components located at the rear of the vehicle. Data for the bulb specifications covers the range from 2000 to 2003.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda S2000 uses the 7443 bulb for its brake lighting across the 2000-2003 model years.
The 7443 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
This bulb follows the T20 wedge form factor, a designation that refers to its physical base style, which uses a plastic wedge rather than a metal pin to seat into the socket.
The 7443 operates on a 12-volt electrical system, consistent with standard automotive voltage.
As a dual-filament bulb, the 7443 carries two separate filaments rated at 21 watts and 5 watts, allowing it to serve both a brighter active brake function and a dimmer secondary function within a single housing.
The Honda S2000 (2000-2003) specifies the 7443 for both the general brake position and the dedicated outer brake position, indicating the same bulb type is used across those two distinct lamp locations.
Because the outer brake and general brake positions share the same 7443 specification, a single bulb type covers both sockets on this vehicle.
The dual-filament nature of the 7443 means substituting a single-filament alternative would result in the loss of one of the two lighting functions at that position.
