Mercedes-Benz E-Class Fog Lights: Specs, Fitment & Common Faults
A genuinely distinctive finding: only one rear fog light is actually fitted on this model, positioned on the driver's side only, and shares its filament with the upper tail light on some versions.

Mercedes-Benz E-Class Fog Lights: Rarely Used, Easy to Forget About Until Needed
Most Mercedes-Benz E-Class owners barely use their fog lights outside a handful of days a year, so a fault can sit unnoticed for a long stretch — until a properly foggy morning exposes it at exactly the wrong moment.
Mercedes-Benz E-Class Fog Lights: What It Does
Front fog lights are angled and positioned to illuminate the road surface in low visibility conditions without creating the glare a standard headlight beam would in fog. Some higher trims of the E-Class integrate fog lights into the same housing as cornering lights or daytime running lights, which affects both the part number and the complexity of any repair.

Fitment & Compatibility
Mercedes-Benz E-Class Fog Lights: Generations, Derivatives & Fog Light Type
| Standard/non-AMG cars | Round halogen fog lamp as standard — confirmed as a genuinely different design from Sport/AMG package cars, not just a finish difference |
|---|---|
| AMG Styling Package cars | A different fog light design specific to this package, not interchangeable with the standard round halogen unit; some non-AMG cars without the Luxury Package have no fog light fitted at all, just a blanking cover |
Not every trim level of the E-Class comes with fog lights fitted as standard, and the housing design often differs between trims that have them integrated with other lighting functions and those with a standalone unit. Always confirm your specific trim's fitment before ordering. Whether you're sourcing a replacement fog lights for your Mercedes-Benz E-Class from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying, and confirm you're ordering the correct side — driver's side (RH in the UK) or passenger side (LH in the UK) — since these are not interchangeable.

A Genuinely Distinctive Finding Worth Knowing — Mercedes-Benz E-Class Fog Lights
If a rear fog light appears not to be working on one side, this is genuinely worth knowing on this model: only one rear fog light is actually fitted, positioned on the driver's side only, rather than there being a matching pair — worth knowing this before assuming a bulb is missing on the opposite side. It's also genuinely worth knowing that the rear fog function on some models shares its bulb filament with the upper tail light, with the fog function simply switching to a higher voltage when selected, meaning if the tail light works, the fog function normally will too.
It's also genuinely worth knowing that replacing any external light bulb with an LED bulb can genuinely trigger a "defective lights" warning message on the dashboard, not necessarily indicating a genuine fault.
