Mitsubishi ASX Fog Lights: Specs, Fitment & Common Faults

On the ASX, if the dashboard genuinely shows fog lights on but the relay isn't clicking, this points toward a ground issue on the relay's coil side specifically.

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 ASX 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

Generations & Fog Light Type

Standard trims	Halogen fog light bulb as standard
Higher trims, later model years	LED fog lights become available further up the range, genuinely a different assembly and connector from the halogen units on lower trims

Not every trim level of the ASX 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 Mitsubishi ASX 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 Useful, Real Diagnostic Distinction Worth Knowing — Mitsubishi ASX Fog Lights

If the dashboard shows the fog lights as switched on, but the actual lights don't illuminate and you can't hear the relay clicking, this is genuinely worth knowing: this specific pattern points toward a ground issue affecting the relay's coil side specifically, rather than the fuse, bulb, or the relay's switching side, which may all test fine individually despite the fault. It's worth checking this specific ground connection before assuming the relay itself needs replacing.

A genuinely useful troubleshooting sequence worth knowing: checking that the fuse has both power and continuity, then confirming the relay itself is functional by testing it in a known-working position such as the horn relay, before finally checking for power at the bulb socket itself with a simple test light, helps systematically narrow down where in the circuit a fault genuinely lies.

It's also genuinely worth knowing that a fog light fuse blowing repeatedly points toward a genuine short circuit in the wiring, a defective bulb drawing excessive current, or a faulty switch causing current spikes — worth having the specific cause identified rather than simply replacing the fuse repeatedly.
