Turning on your car's headlights is typically done using a multi-function stalk on the left side of the steering column or a dial on the dashboard. For most vehicles, you simply rotate the dial or end of the stalk to one of several settings: Off, Parking Lights, Low Beams, and often Auto. The Auto setting, which uses a light sensor to automatically turn lights on at dusk or in tunnels, is the most convenient and safest option for daily driving.
The correct setting depends on visibility, not just the time of day. You are legally required to turn on your low beams from sunset to sunrise and during any adverse weather conditions like rain, fog, or snow that reduce visibility. Relying on Daytime Running Lights (DRLs) is a common mistake; these are dimmer lights that only illuminate the front of the car, leaving your tail lights off and making you invisible from behind in low light. Always manually select the low beam setting if your car lacks an Auto feature.
For high beams, used on dark, unlit roads, you usually push the stalk away from you until you feel a click. A blue indicator light on your dashboard will confirm they are on. You must dim them for oncoming traffic. To flash your high beams momentarily (e.g., to signal another driver), pull the stalk toward you.
| Headlight Setting | When to Use It | Key Consideration |
|---|
| Auto | Default for most driving; activates in low light. | Ensure the windshield sensor area is clean for accurate operation. |
| Off | When the engine is off or parked for extended periods. | Never use while driving; can drain the battery if left on. |
| Parking Lights | When parked temporarily on a dimly lit road for visibility. | Not bright enough for active driving. |
| Low Beams | Night driving, rain, fog, snow, and any low-visibility condition. | Mandatory for safety; the most commonly used setting. |
| High Beams | Dark, rural roads with no oncoming traffic. | Must be dimmed for other vehicles to avoid blinding drivers. |
| Front Fog Lights | Heavy fog, snow, or dust (if equipped). | Use with low beams; not a substitute for them. |
| Rear Fog Light | Extremely low visibility conditions (common in European cars). | Much brighter than standard tail lights; use sparingly. |
Consulting your owner's manual is the best way to understand the specific controls in your vehicle, as the location and symbols can vary between manufacturers like Toyota, Ford, and BMW.
