The Mercedes-Benz E55 AMG front fog light requires 9006, H11, or H1 bulb sizes, while the rear fog light uses a 1156 bulb size. The replacement chart covers 1999 to 2006 model production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercedes-Benz E55 AMG front fog light specification shows three distinct bulb types across the 1999-2006 model years: H1 for 1999-2002, H11 for 2003-2004, and 9006 for 2005-2006. These are not interchangeable, as each uses a physically different base design.
The H1 bulb operates on an ECE standard and uses a P14.5s single-pin base. It runs at 12V and 55W and holds approval in the US and Japan in addition to European markets.
The H11 bulb also follows the ECE standard and uses a PGJ19-2 base. Like the H1, it operates at 12V and 55W and carries US approval, though its base configuration is entirely different from the H1.
The 9006 bulb follows the ANSI standard, which is specific to the US and Canada. It uses a P22d base and operates at 12V and 55W. Despite sharing the same wattage as the H1 and H11, its base is incompatible with either of those sockets.
All three front fog light bulb types are single-filament halogens rated at 55W, meaning each controls only one lighting function rather than combining multiple functions within a single bulb.
The rear fog light on the Mercedes-Benz E55 AMG, available for the 1999-2002 model years, uses the 1156 bulb. This is an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V and 21W.
The 1156 bulb's BA15s bayonet base is a twist-lock style mount, which is mechanically distinct from the screw-pin and wedge bases used by the halogen fog light bulbs in the front positions.
At 21W, the 1156 rear fog light bulb draws significantly less power than the 55W halogen bulbs used in the front fog positions. Substituting a higher-wattage bulb in a socket rated for 21W risks overloading the circuit or damaging the housing.
The front fog light socket changed three times across the E55 AMG's production run, meaning a replacement bulb sourced for a 2000 model year vehicle would not fit a 2004 or 2006 model year vehicle without a socket adapter or wiring modification.
The ECE-standard bulbs (H1 and H11) used in the front fog positions carry broader international approval than the ANSI-standard 9006, which is certified only for the US and Canadian markets.
