With such a heavy emphasis on safety, it’s no wonder that car manufacturers are always looking for ways to improve the visibility of their vehicles. As a result, headlights have become increasingly important over the years. Modern cars have a variety of different headlight options, and knowing how to use them properly is essential for safe driving. In this article, we will discuss the different types of headlights and how to turn them on. We will also provide some tips on how to use your headlights effectively.
The most common type of headlight is the halogen headlight. Halogen headlights use a filament that is heated until it glows. These headlights are relatively inexpensive and provide good visibility in most conditions. However, they are not as bright as some other types of headlights, such as HID headlights or LED headlights. HID headlights use a high-intensity discharge lamp to produce light. These headlights are very bright and have a long lifespan. However, they are also more expensive than halogen headlights. LED headlights use light-emitting diodes to produce light. These headlights are very bright, energy-efficient, and have a long lifespan. However, they are also the most expensive type of headlight.
Now that you know the different types of headlights, let’s talk about how to turn them on. The headlight switch is usually located on the dashboard. It is typically a rotary knob or a lever. To turn on the headlights, simply turn the knob or move the lever to the “on” position. Some vehicles have a separate switch for the daytime running lights. These lights are less bright than the headlights, and they are designed to make your vehicle more visible during the day. To turn on the daytime running lights, simply turn the switch to the “on” position.
Locate the Headlight Switch
Every vehicle’s headlight switch is unique, but they usually share similar characteristics. Familiarize yourself with the following steps to locate the headlight switch:
- Scan the Dashboard: Look for a rotary knob, lever, or button labeled "Headlights" or "Lights." It’s typically located on the left side of the steering column or center console.
- Check the Steering Column: Examine the stalk or lever attached to the steering column. It might have a symbol like a light bulb or a dial with "0" (off) and other positions for different headlight settings.
- Inspect the Multi-Function Lever: In some modern vehicles, the headlight controls are integrated into a multi-function lever near the steering wheel. Look for buttons or dials that say "Lights" or have headlight symbols.
- Refer to Your Owner’s Manual: If you’re still having trouble, consult your vehicle’s owner’s manual. It will provide precise instructions on the location and operation of the headlight switch.
| Control Type | Common Location |
|---|---|
| Rotary Knob | Left side of steering column or center console |
| Lever | Steering column stalk or center console |
| Button | Integrated into multi-function lever or center console |
Turn the Headlight Knob
Most cars have a headlight knob located on the dashboard. The knob typically has several settings, such as:
| Setting | Function |
|---|---|
| Off | Turns off the headlights |
| Parking Lights | Turns on the parking lights only |
| Headlights | Turns on the headlights and taillights |
| High Beams | Turns on the high beams. Note that high beams should only be used when driving on dark roads with no oncoming traffic. |
| Auto | Automatically turns on the headlights when it gets dark outside. |
To turn on the headlights, simply turn the headlight knob to the “Headlights” setting. The headlights will then turn on automatically.
Use Dimmed Headlights
On most vehicles, you can turn on dimmed headlights by rotating the headlight switch to the first position. This position will turn on the headlights and taillights, but not the high beams. Dimmed headlights are designed to provide adequate illumination while driving in low-light conditions, such as dawn, dusk, or through fog.
It’s important to note that dimmed headlights are required by law in many areas when driving at night or in conditions with reduced visibility. Using only your parking lights is not sufficient, as they do not provide enough illumination to see the road ahead or be seen by other drivers.
Refer to the following table for a summary of when to use dimmed headlights:
| Conditions | Use Dimmed Headlights |
|---|---|
| Nighttime | Yes |
| Dawn or dusk | Yes |
| Fog or heavy rain | Yes |
| Driving through tunnels | Yes |
| When visibility is reduced | Yes |
By using dimmed headlights appropriately, you can help improve your visibility and the safety of yourself and others on the road.
Troubleshoot Headlight Problems
1. Check the bulbs:
Replace any burned-out bulbs with new ones of the correct type and wattage.
2. Check the fuses:
Locate the fuse box and identify the fuse responsible for the headlights. Replace any blown fuses.
3. Inspect the wiring:
Look for any loose or damaged wires in the headlight assembly. Repair or replace any faulty wiring.
4. Check the headlight switch:
Ensure that the headlight switch is turned to the “on” position.
5. Check the relay:
Locate the headlight relay and replace it if it’s defective.
6. Check the alternator:
Test the alternator to ensure it’s providing sufficient power to the headlights.
7. Clean the headlight contacts:
Remove any dirt or corrosion from the headlight contacts using a brush or sandpaper.
8. Inspect the headlight lenses:
Check for any clouding or yellowing on the headlight lenses. Clean or replace them if necessary.
9. Check the headlight level:
Adjust the headlights to ensure they’re properly aligned and not aimed too high or too low. You can use a simple headlight alignment tool to adjust the headlights yourself or have it done professionally.
| Headlight Alignment Guidelines | Vertical Alignment | Horizontal Alignment |
|---|---|---|
| Distance from wall to headlights (feet) | 25 | 25 |
| Height from floor to headlights (inches) | 25 | 36 |
| Measurement from center of beam to floor (inches) | 12.5 | Depending on vehicle |
Safety Precautions for Headlight Use
1. Turn off headlights when following another car.
Using high beams when following another car can create a blinding effect and increase the risk of an accident.
2. Use low beams in foggy or rainy conditions.
High beams can reflect off of raindrops or fog particles, making it difficult for drivers to see.
3. Keep headlights clean.
A dirty headlight lens can reduce the amount of light that is emitted.
4. Replace burned-out bulbs promptly.
A single burned-out bulb can significantly reduce a vehicle’s visibility.
5. Aim headlights properly.
Misaligned headlights can blind oncoming drivers or create glare for the driver.
6. Avoid using aftermarket headlights.
Aftermarket headlights may not meet safety standards and can create glare for other drivers.
7. Use daytime running lights (DRLs).
DRLs make vehicles more visible during the day.
8. Be aware of oncoming traffic.
When driving at night, be aware of oncoming traffic and dim your headlights if necessary.
9. Use fog lights only when visibility is low.
Fog lights are designed to improve visibility in foggy conditions, but they can create glare for other drivers if used inappropriately.
10. Consider installing automatic headlights.
Automatic headlights automatically turn on and off based on the ambient light level, providing added convenience and safety.
| Headlight Type | Appropriate Use |
|---|---|
| Low beams | Regular nighttime driving |
| High beams | Only when there is no oncoming traffic or vehicles ahead |
| Fog lights | Only when visibility is low due to fog |
| DRLs | During the day, to increase visibility |
