Additional Notes

The Mercedes-Benz E430 uses the 6411 bulb size for the dome light across all listed model years, spanning 1998-2002.
The 6411 is an ANSI-standard designation recognized in both the United States and Canada, meaning it follows a standardized specification shared across North American markets.
The 6411 is a festoon-style bulb, a form factor characterized by a cylindrical body with metal end caps that make contact within a spring-loaded holder rather than using a traditional socket.
The bulb measures 36mm in length, which is a critical fitment factor, as festoon bulbs must match the holder span precisely to seat correctly and maintain electrical contact.
The 6411 uses an SV8.5 base, a designation that refers to the end cap width of 8.5mm, which must correspond to the vehicle's dome light housing to ensure a proper fit.
The bulb operates at 12 volts and 5 watts, consistent with standard low-draw interior lighting in passenger vehicles of this class.
Because festoon bulbs are sized by length, a 6411 replacement must be 36mm; substituting a festoon bulb of a different length, such as 31mm or 41mm, would result in an improper fit regardless of voltage or wattage compatibility.
