A Genuinely Useful, Systematic Diagnostic Technique Worth Knowing — Toyota Avensis Fog Lights
If both fog lights have stopped working together with good bulbs confirmed, this is genuinely worth trying: with the fog light switch activated, listen carefully at the relay for an audible click. If you hear no click at all, the fault genuinely lies somewhere before the relay — the switch, wiring, or fuse box. If you do hear the relay click but the lights still don't illuminate, the fault lies further downstream instead.
It's also worth knowing that both front fog lights commonly share a single fuse and relay, so if only one side has failed while the other works, this points toward something specific to that one side rather than the shared circuit.
Toyota Avensis Fog Lights: Rarely Used, Easy to Forget About Until Needed
Fog lights are one of those parts on the Toyota Avensis nobody checks until they need them, and with most owners using them only a few times a year, a fault can linger unnoticed for a long time before a foggy morning finally reveals it.

Toyota Avensis 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 Avensis 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
Toyota Avensis Fog Lights: 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 Avensis 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 Toyota Avensis 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.
