Peugeot 2008 Fog Lights: Specs, Fitment & Common Faults

On the 2008, there genuinely is no dedicated fuse for the fog lights — they're controlled by the BSI module, and a reset often fixes faults that look like wiring problems.

Confirmed: There Genuinely Is No Dedicated Fuse to Find

If your fog lights have stopped working and you've spent time searching the fuse box diagram without finding one specifically labelled for front or rear fog lights, this is genuinely worth knowing before you keep looking: on many Peugeots, fog lights aren't wired through a conventional dedicated fuse at all. Instead, they're controlled directly by the BSI (Built-in Systems Interface — the car's central electrical control module), meaning there's simply no fuse to locate in the fuse box, regardless of how carefully you check the diagram. This is a repeatedly reported source of genuine confusion, with multiple owners independently confirming they searched exhaustively and found no fog light entry anywhere in their fuse box layout.

A genuinely useful, real fix worth trying: since the BSI controls these lights directly rather than through a simple fuse, a BSI reset — achieved by disconnecting the battery for a period, or via a proper diagnostic tool — has resolved fog light faults for documented owners after bulbs and wiring were confirmed fine, essentially clearing a confused or stuck state in the module itself rather than pointing to any physical component failure. This is worth trying before assuming a wiring fault or paying for extensive diagnostics.

If you've swapped bulbs and the lights still don't work, checking for corrosion or a poor connection at the fog light switch and its wiring is also worth doing, since a faulty switch can prevent the BSI from ever receiving the signal to activate the lights in the first place, even with everything else in the circuit working correctly.

Rarely Used, Easy to Forget About Until Needed

Fog lights sit unused for most owners most of the year, which means a fault can go unnoticed for a long time — right up until a genuinely foggy morning makes the problem obvious at the worst possible moment.

Before you buy: fog light fitment and bulb type vary by trim — not every trim level includes them as standard. Always confirm against your VIN before ordering.

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 2008 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

Not every trim level of the 2008 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 Peugeot 2008 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.

Common Faults

What to Look For

One side not working — usually a blown bulb, the most common and easiest fault to fix.
Neither side working — more likely a blown fuse or a faulty switch than two bulbs failing simultaneously.
Condensation inside the lens — points to a failed seal, worth addressing before it affects the bulb or wiring.
Cracked housing from front-end impact — common given their low mounting position, usually a straightforward like-for-like replacement.

DIY Replacement Difficulty

Bulb replacement is usually an easy DIY job, though access varies — some versions require reaching up from underneath via the wheel arch liner, others come apart from the front. Full housing replacement is similarly straightforward on most versions. Expect 15–30 minutes for a bulb swap, longer if the housing itself needs replacing.

OEM vs. Aftermarket

Reputable aftermarket fog light units and bulbs are a reliable, cost-effective alternative to OEM parts for the vast majority of cases, since this is a relatively simple lighting component without the complexity of adaptive or LED headlight systems.
