Toyota GT86 Fog Lights: OEM Part Number

Accuracy note: we weren't able to verify a confident Toyota GT86 fog lights part number at the time of writing. Please confirm the correct part via a Toyota dealer or parts specialist using your VIN.

A Genuinely Useful, Systematic Diagnostic Technique Worth Knowing — Toyota GT86 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.

A genuinely important finding worth knowing if a fuse and relay both test as functional: a documented professional diagnosis found that even with a confirmed good fuse and relay, no power was reaching the fog lamp relay at all — the eventual conclusion being that the fuse box itself had failed internally and needed replacement, rather than any individual fuse or relay within it.

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 GT86 Fog Lights: Rarely Used, Easy to Forget About Until Needed

Fog lights are one of those parts on the Toyota GT86 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.

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.

Toyota GT86 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 GT86 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 GT86 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 GT86 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 GT86 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.
