Cheap Mercedes-Benz B-Class Fog Light

Front fog lights were fitted to many B-Class variants but were not standard across every trim level — they were an optional or trim-dependent fitment, so not every B-Class left the factory with them. If your car has fog light blanks in the bumper rather than actual fog lights, it may never have had them fitted from new. When sourcing a used fog light from a breaker, confirm against your registration that the donor car also had fog lights fitted, as bumper designs can differ between fog-light and non-fog-light versions.

No — the W245 (2005–2011) and W246 (2011–2018) are entirely different generations with different front-end designs, so fog lights are not interchangeable between them. Always match the part to the correct generation, which you can confirm from your registration plate or V5C document. A breaker will be able to identify the correct part for your specific car once you give them your reg.

This is an important question because the W246 generation received a facelift in 2015, so both a 2012 and a 2014 car sit in the pre-facelift W246 period and the fog lights should be from the same design phase. That said, always confirm with the breaker against your registration, as minor running changes can occur within a model year that are not always publicly documented. A good breaker will cross-reference the part visually before dispatch.

The W246 B-Class received a facelift around 2015, which typically brought changes to the front bumper, lights and grille — meaning pre-facelift (2011–2014) and post-facelift (2015–2018) fog lights may well differ in design and mounting. Whether a specific fog light crosses that facelift boundary is something you must confirm with the breaker against both registrations, as fitment across a facelift cannot be guaranteed without physically comparing the parts. Do not assume they interchange simply because both cars are W246 generation.

Trim level — whether SE, Sport, or AMG Line — does not fundamentally affect fog light fitment on the B-Class, as the front-end structure is shared across trims within the same generation and facelift period. However, you may find cosmetic differences such as bezel colour or surround finish between trims, so bear that in mind if you want the replacement to match your car's appearance exactly. Always match generation and facelift period first, then discuss cosmetic finish with the breaker.

On a UK right-hand-drive B-Class, the near side (NS) is the passenger side (left as you face the car from the front) and the off side (OS) is the driver's side (right). Fog lights are side-specific and will not swap left to right, so confirm which side you need before contacting a breaker. It is also worth noting whether your car has a single front fog light or a pair, as some trim and option combinations differ, and the breaker can advise once you provide your registration.
