The Mercedes-Benz SLK32 AMG front fog light uses H7 and 9006 bulb sizes, while the rear fog light requires a 1156 bulb size. The replacement chart covers 2002 to 2004 model 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 H7 and 9006 bulbs share the same 12V, 55W electrical rating, making them functionally equivalent in power output despite originating from different standardization bodies. The H7 follows the ECE standard used in Europe and worldwide, while the 9006 follows the ANSI standard used in the US and Canada.
Although the H7 and 9006 operate at identical wattage, they are not interchangeable. The H7 uses a PX26d base and the 9006 uses a P22d base, meaning the physical connector and locking mechanism differ between the two bulb types.
The Mercedes-Benz SLK32 AMG front fog light specification changed from the 9006 bulb in 2002-2003 to the H7 bulb in 2004, representing a shift from an ANSI-standard fitting to an ECE-standard fitting.
Because the front fog light base type changed between model years, a 2004 SLK32 AMG front fog light housing is not compatible with the 9006 bulb used in 2002-2003 models, and vice versa.
The H7 bulb, specified for the 2004 front fog light, holds approval across multiple regulatory regions, including the US, Japan, and markets governed by ECE standards.
The 1156 bulb is a single-filament type with a BA15s bayonet base, which is a twist-and-lock style mount. At 12V and 21W, it operates at significantly lower wattage than the halogen fog light bulbs used at the front.
The rear fog light specification for the SLK32 AMG remained consistent across all three model years covered, with the 1156 bulb specified for 2002-2004.
