Additional Notes

The Mercedes-Benz E430 uses the H6W bulb size for the map light across all listed model years, spanning 1998-2002.
The H6W is an ECE-standardized bulb type, meaning it conforms to regulations recognized across Europe and internationally.
H6W bulbs operate on a 12-volt electrical system, which is standard for passenger vehicles in this class.
The H6W has a rated wattage of 6W, placing it in the low-power range typical of interior courtesy and map lighting applications.
H6W bulbs use a BAX9s base, which is an offset pin bayonet fitting. The pin offset is a deliberate design feature that prevents incorrect insertion of the bulb into the socket.
The H6W is a single-filament bulb, meaning it serves one lighting function only, with no secondary filament for a dimmed or alternate mode.
The BAX9s base is not universally interchangeable with other bayonet-type bases. Bulbs with a standard BA9s base, for example, have a centered pin arrangement and are not a direct fit for sockets designed for the offset BAX9s configuration.
