The fog light button is the switch labeled with the fog-light symbol, typically found on the headlight control dial or the steering-column stalk.
Fog lights are designed to improve visibility in fog, rain, or snow. They are separate from daytime running lights and low-beam headlights. Since layouts vary by manufacturer and model, use this guide to locate the fog-light control on most passenger cars. Some newer models can even activate fog lights automatically when conditions warrant it, without a manual switch.
Common locations for fog-light controls
Where the switch sits depends on design, but these are the most common spots:
- On the headlight control dial: rotate to the fog-light symbol or press a dedicated fog button integrated into the dial.
- As a separate button on the dashboard near the steering wheel (often with a blue indicator when active).
- On the left or multifunction stalk (some models require pulling the stalk outward or twisting the end to engage front fog lights).
- Inside the infotainment or climate menu in very new vehicles (less common).
If you’re unsure, check the owner's manual for the exact location for your specific model or ask a dealer. The dash indicator light will usually illuminate when the lights are on.
Recognizing fog-light symbols
Symbols differ between front and rear fog lights, but you can usually tell by color and orientation. In many markets, front fog lights are indicated with a white or blue symbol and a beam pattern that points downward; rear fog lights use a red variant of the same symbol and a hint of a rear beam.
- Front fog lights: icon shows a headlamp with horizontal lines or a beam extending to the left; often blue or white.
- Rear fog lights: icon is similar to the front symbol but red and sometimes incorporates a vertical line or extra dash to distinguish rear lighting.
Again, the exact icon can vary by car maker, so if the symbol isn’t obvious, consult the manual or look for a dash tooltip when cycling the lights.
Testing the fog lights safely
Always test in a safe, legal environment before driving in poor visibility. Here are steps to verify proper operation without causing danger:
- With low beams on, switch to the fog-light control and check for the dash indicator to illuminate.
- Ensure that only the fog lights (and low beams) are active—turn off other auxiliary lights if needed.
- In some vehicles, there is a separate rear fog-light switch; ensure it’s off unless conditions require it.
Note: In many regions, rear fog lights should be used sparingly and only when visibility is significantly reduced to avoid blinding other drivers.
What to do if you still can’t find it
Look for a dedicated push button, a symbol on the headlight dial, or a function on the stalk. If the symbol is unfamiliar, consult the owner’s manual or manufacturer support page for your exact model and year. A quick online search with your car’s year, make, and model can yield a diagram of the control layout.
Summary
The fog light button is typically the switch labeled with the fog-light icon, found on the headlight control dial or the steering-column stalk. Locations vary by model, so check the manual or try the common spots described above. Remember to use fog lights only when visibility is truly reduced and to switch them off when conditions improve.
