Additional Notes

The Mercedes-Benz SLK32 AMG uses two distinct dome light bulb types across its model years: the H6W and the 6411, each governed by different regional standards.
The H6W follows the ECE standard, which applies to Europe and worldwide markets, while the 6411 follows the ANSI standard, which applies to the US and Canadian markets.
The 2004 SLK32 AMG specifies the H6W bulb for the dome light position, whereas the 2002-2003 model years specify the 6411 bulb.
The H6W is a single-filament signalling bulb rated at 12V and 6W, mounted on a BAX9s base, which is an offset pin-type base that physically prevents incorrect installation of incompatible bulbs.
The 6411 is a festoon-style bulb rated at 12V and 5W, with a 36mm length and an SV8.5 base, which is a standard cylindrical contact base common to many interior lighting applications.
The H6W and 6411 are not interchangeable. Their base types differ entirely, with the BAX9s being a pin-offset base and the SV8.5 being a festoon end-cap base, making physical fitment between the two impossible without modification.
The wattage also differs between the two bulbs. The H6W draws 6W while the 6411 draws 5W, reflecting a slight difference in light output and power consumption between the two standards.
