Learning how to turn on the headlights in a car is a fundamental skill for every driver, yet the controls can vary between models. Illuminating the road ahead begins with finding the headlight control stalk or panel in your specific car model. This guide will walk you through every common method, symbol, and setting to ensure you can see and be seen in any driving condition.
How To Turn On The Headlights In A Car
The primary control for your headlights is usually located in one of two places. Most often, you will find it on a stalk, or lever, attached to the left side of the steering column. In other vehicles, especially some SUVs and older models, you might find a rotary dial or button panel on the dashboard to the left of the steering wheel. The first step is always to locate this control before you start driving at dusk or in poor weather.
Once you’ve found the control, you’ll see several settings marked with international standard symbols. These symbols are your key to operating the lights correctly. They are designed to be universal, so even in a rental car or a friend’s vehicle, you can quickly identify the right function. Let’s break down what each symbol means and when to use it.
Understanding Headlight Symbols And Settings
Every headlight control features a series of icons that rotate or click through positions. Here is what each one typically means:
- O or OFF: This position turns all exterior lights off. Your daytime running lights may remain on in some cars.
- Auto (A): An ‘A’ inside a light icon. This setting lets the car’s light sensor automatically turn headlights on and off based on ambient darkness.
- Parking Lights: Symbolized by two small, facing lamps. This turns on small marker lights at the front and rear, but not headlights.
- Low Beam Headlights: The main headlight symbol, a lamp icon with lines sloping downward. This is your standard setting for night driving.
- High Beam Headlights: A lamp icon with straight, horizontal lines projecting forward. This provides maximum forward illumination.
- Front Fog Lights: A lamp icon with a wavy line through the light beams, pointing left.
- Rear Fog Light: A similar lamp icon with a wavy line, but pointing right.
Step-By-Step Instructions For Common Controls
Using A Steering Column Stalk
The column stalk is the most common setup in modern vehicles. Here is how to operate it:
- Sit in the driver’s seat and locate the stalk behind the left side of the steering wheel.
- Look for a rotating ring or knob at the end of the stalk. It may also be a twistable section in the middle.
- Rotate the control knob through its positions. You will feel it click into place at each setting.
- Turn from ‘OFF’ or ‘O’ past the parking light symbol to the low beam headlight symbol.
- To activate high beams, push the entire stalk forward away from you. You should see a blue indicator light on your dashboard.
- To momentarily flash the high beams (e.g., to signal another driver), pull the stalk gently toward you, then release.
Using A Dashboard Rotary Dial
If your car has a dashboard dial, the process is slightly different but just as simple.
- Locate the dial on the dashboard, typically to the left of the steering column or on the center console.
- Grasp the dial and rotate it clockwise. It will cycle through the settings: Off, Parking Lights, Low Beams.
- Stop rotating when the dial’s pointer aligns with the low beam headlight symbol.
- For high beams, you usually still use a separate stalk control. Push the stalk forward to engage them.
- For fog lights, you may need to pull the dial outward to a second position or press a separate button nearby.
How To Operate Automatic Headlights
Most newer cars come equipped with an ‘Auto’ setting, which is highly recommended for convenience and safety. When you select ‘Auto’, a light sensor on the dashboard (often near the windshield) measures outside light levels. The car will then automatically switch the low beam headlights on at dusk, in tunnels, or during heavy rain, and turn them off when sufficient light returns.
To use automatic headlights, simply rotate your control stalk or dial until the pointer lines up with the ‘A’ or ‘Auto’ symbol. Ensure the dashboard sensor area is not covered by a dashboard mat or other object, as this can prevent them from working correctly. Remember, even with automatic lights, you are still responsible for manually activating high beams or fog lights when needed.
When And Why To Use Different Light Settings
Using the correct setting is crucial for safety and legality. Here’s a practical guide:
- Daytime Running Lights (DRL): These are often always on and are not a substitute for headlights. They improve daytime visibility but do not illuminate the road or turn on rear lights.
- Low Beams: Use these from sunset to sunrise, in fog, rain, snow, or any time visibility is less than clear. They are also required when using windshield wipers in many states.
- High Beams: Use these only on dark, open roads with no oncoming traffic. You must dim them when within 500 feet of an approaching vehicle or when following within 300 feet of another car.
- Fog Lights: Use these in dense fog, heavy snow, or dust. The wide, low beam cuts through the fog better than high beams, which will create a blinding glare. Remember to turn them off when conditions improve.
- Parking Lights: These are for temporary use when parked on a dimly lit road to make your car visible. They are not designed for driving.
Troubleshooting Common Headlight Problems
Sometimes, headlights don’t work as expected. Before calling a mechanic, check these common issues.
Headlights Won’t Turn On
If you turn the switch and nothing happens, follow these steps:
- Check if only one or both lights are out. If it’s just one, it’s likely a burned-out bulb.
- Verify the control is set to the low beam symbol, not just the parking lights.
- Look at your dashboard for a headlight indicator. If it’s lit, the switch is on but power isn’t reaching the bulb.
- Check your car’s fuse box. The owner’s manual will show you which fuse corresponds to the headlight circuit.
- Ensure your vehicle is not in ‘accessory’ mode; some cars require the engine to be running for lights to operate.
High Beams Not Working
If your low beams work but high beams do not, the issue could be separate.
- The high beam bulb may be burned out (many cars have separate bulbs for high and low beams).
- The fuse for the high beam circuit could be blown.
- The stalk switch itself might be faulty, preventing the signal from being sent when you push it forward.
Important Safety And Legal Considerations
Proper headlight use is not just about convenience; it’s a legal requirement. Driving without lights in low-visibility conditions can result in fines and is a major safety hazard. Most states have laws requiring headlight use from sunset to sunrise and during inclement weather. Furthermore, if your vehicle is equipped with automatic headlights, you cannot rely on them completely. It is the driver’s ultimate responsibility to ensure the lights are on when needed.
Always perform a light check when you start your car in the evening. A quick glance at the light pattern on the garage wall or a quick walk-around can confirm all lights are functioning. This includes headlights, tail lights, brake lights, and turn signals. Keeping your headlight lenses clean is also vital, as a layer of grime can reduce light output by over 50%.
Adapting To Different Vehicle Models
The basic principles are the same, but controls can differ. In a Toyota or Honda, you’ll likely find a column stalk. In some older Fords or Volkswagens, a dashboard dial is common. Luxury brands like Mercedes or BMW often integrate the control into a more complex menu on a separate panel or steering wheel button cluster. The key is to take a moment when you enter an unfamiliar vehicle to find the control and identify the symbols before you begin driving.
If you are ever unsure, the fastest resource is your vehicle’s owner’s manual. It will have a dedicated section with diagrams showing the exact location and operation of all light controls. Keeping this manual in your glove box is a smart habit for every driver.
FAQ: Frequently Asked Questions
What if my car doesn’t have an “Auto” headlight setting?
If your car lacks an automatic setting, you must manually turn the headlights on and off. Develop a habit of turning them on when your windshield wipers are in use or as soon as the sun begins to set. It’s better to have them on a little early than too late.
Is it illegal to drive with only daytime running lights on at night?
Yes, in virtually all jurisdictions. Daytime running lights do not activate your rear tail lights, making you invisible to drivers approaching from behind. This creates a severe collision risk. Always ensure your proper low beam headlights are activated.
How do I turn on fog lights in my specific car?
Fog light controls vary. Often, you must first turn on your low beam headlights. Then, either pull the headlight stalk toward you, rotate a separate ring on the stalk, or press a dedicated button on the dashboard marked with the fog light symbol. Consult your manual for the precise method.
Why won’t my headlights turn off automatically?
This is often caused by a faulty light sensor or a setting in your vehicle’s computer. Some cars have a “follow-me-home” delay feature that keeps lights on for a period after you exit. Check your manual for how to adjust this setting. If the problem persists, the sensor may need to be cleaned or replaced by a technician.
Can I get a ticket for having a headlight out?
Absolutely. Driving with a single headlight out is a common traffic violation. It reduces your visibility and makes your vehicle appear as a motorcycle to other drivers, leading to confusion and accidents. Replace burned-out bulbs as soon as possible for safety and to avoid a fine.
Mastering how to turn on your headlights is a simple but essential part of responsible driving. By understanding the symbols, locating the controls in your vehicle, and using the appropriate setting for the conditions, you ensure a safer journey for yourself and everyone else on the road. Make it a routine part of your pre-drive check, just like fastening your seatbelt.
