Fog Light Indicator on a Subaru WRX
This is usually informational. Address it at your convenience.
What the Fog Light Indicator Means on a Subaru WRX
On the Subaru WRX, this symbol means the fog lights are active. Rear fog lights are very bright and should be turned off in clear conditions to avoid dazzling drivers behind you.
How Urgent Is the Fog Light Indicator?
Urgency level for this indicator on the Subaru WRX: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Fog Light Indicator appeared, how the Subaru WRX is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
Common Symptoms Alongside the Fog Light Indicator
The Fog Light Indicator on your Subaru WRX is one data point, and the symptoms around it are the rest of the story. Perhaps the engine feels different, a gauge reads unusually, or the car behaves normally but the symbol simply will not clear. Note everything you observe, because the pattern of symptoms on the Subaru WRX is exactly what turns a vague warning into a specific, fixable diagnosis.
- Green (front) or amber (rear) fog symbol lit
- Corresponds to the fog light switch position
- No fault behaviour
What Causes the Fog Light Indicator to Come On?
Why did the Fog Light Indicator come on in your Subaru WRX? The honest answer is 'it depends', but the possibilities cluster into a recognisable set of causes.

- Fog lights switched on (normal)
- Switch left on inadvertently

Is It Safe to Drive With the Fog Light Indicator On?
Safe-to-drive depends on judgement, and here is the technician's version for a Subaru WRX: respect the colour, respect the behaviour. Given this light's low urgency, treat any red or flashing warning as a stop-now signal. If everything feels normal and the light is amber, a short, cautious drive to a garage is typically fine, provided you do not delay the actual diagnosis.

Frequently Asked Questions
Why is the Fog Light Indicator on in my Subaru WRX?
Your Subaru WRX turned on the Fog Light Indicator after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Fog Light Indicator on?
Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Subaru WRX, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Fog Light Indicator on a Subaru WRX?
Cost varies widely because the Fog Light Indicator can stem from several causes on a Subaru WRX. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour. Getting the specific trouble code first is what lets a shop quote accurately instead of estimating blind.
Will the Fog Light Indicator reset itself on a Subaru WRX?
If the trigger was temporary, a Subaru WRX may turn the Fog Light Indicator off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
