What Are Fog Lights and What Do They Do?
Fog lights, identified by the fog light symbol, are one of the most important pieces of equipment used to increase driving safety in weather conditions that reduce visibility, such as heavy fog, rain or snow. Therefore, knowing what fog lights do, how to turn them on and when it is appropriate to use them is crucial for safe driving.
Fog lights are special lighting units positioned close to the ground that help you see the road more clearly in low visibility conditions. Unlike normal headlights, they emit light at a wider angle and from a lower level. This prevents the light from being reflected back by fog or raindrops and dazzling your eyes.
The primary purpose of fog lights is to ensure you can see the road clearly when visibility is reduced and to increase the visibility of your vehicle to other drivers. The fog light indicator is usually yellow or green and has a special symbol that indicates the lights are on. This symbol is also known as the fog light symbol.
What Do Fog Lights Do?
Fog lights are special lighting equipment designed to improve the driver's road visibility in poor weather conditions such as heavy fog, snow or rain.
The benefits provided by the fog light symbol can be summarised as follows:
- It shows the road more clearly in low visibility. The light beam spreads parallel to the ground, thereby increasing your visibility.
- Makes it easier for oncoming vehicles to see you. Your visibility increases.
- They operate more efficiently than standard headlights. They particularly reduce the reflection effect created by low beams in fog.
- They ensure safe driving in adverse weather conditions. This reduces the risk for both you and other drivers on the road.
Additionally, fog lights enhance your reflexes and provide extra safety in preventing accidents, especially in urban and rural areas during sudden fog or heavy rain. Keeping headlights at the correct angle and clean is important for maximum performance. Therefore, fog lights are not just an aesthetic vehicle accessory but a critical system that enhances driving safety.
What Does the Fog Light Symbol Mean?
The fog light symbol is the icon that indicates the fog lights are active on the vehicle dashboard. It usually has the following images:
- Front fog light indicator: A lighting symbol with lines extending sideways.
- Rear fog light indicator: A similar symbol, but with the lines pointing in the opposite direction.
The purpose of the fog light indicator is to clearly inform you whether the fog lights are on or off. Keeping fog lights on is particularly important in dense weather conditions, so this symbol on the dashboard serves as a constant reminder to drivers.
Furthermore, not switching on fog lights unnecessarily prevents glare for other drivers. In some vehicles, the fog light symbol on the panel also provides additional safety by indicating light intensity or fault conditions.
How to Switch On Fog Lights?
The method for turning on fog lights may vary depending on the vehicle model, but the basic steps are similar for most vehicles. Fog lights are a special type of lighting used to improve visibility in poor weather conditions, and turning them on correctly is important for driving safety.
Fog lights are usually turned on as follows:
- Turn the headlight control.
- The dipped headlights are activated. In some vehicles, the fog light indicator only works when the dipped headlights are on.
- The fog light indicator button is pressed.
- You can turn on the fog light indicator by pressing the button located on the headlight lever on the left side of the steering wheel or on the front console.
- The fog light indicator on the instrument panel is checked. When the symbol is lit, it indicates that the lights are on.
The rear fog light indicator is usually activated by a separate button. As it emits a stronger light than the front fog light indicator, it should be used with caution. Furthermore, leaving the fog lights on unnecessarily for long periods can dazzle other drivers and place extra strain on the vehicle's electrical system.
When Should Fog Lights Be Used?
Fog lights should only be used when visibility is seriously reduced. Such situations include heavy fog, heavy snowfall, heavy rain that reduces the driver's visibility, foggy valleys or mountain roads, and smoky, visibility-reducing environmental conditions.
Under normal weather conditions, turning on fog lights can both disturb oncoming drivers and violate traffic regulations. Therefore, fog lights should only be used when truly necessary.
Fog Light Bulb Selection
Fog light bulbs are specially designed to offer better performance in foggy conditions. Key points to consider when selecting bulbs are:
- Your vehicle's bulb compatibility
- Wattage and light colour values
- Halogen, LED or xenon options
- Brightness levels suitable for your driving conditions
LED models are more frequently preferred due to their long life and low energy consumption. Halogen bulbs, on the other hand, are a more affordable option. Although bulb replacement is simple, depending on the vehicle model, it may be necessary to visit a service centre.
Why Does the Fog Light Indicator Flicker?
The fog light indicator normally stays lit; however, if it flashes, there may be various issues. A faulty headlight, a bulb that is about to burn out, an interruption in the electrical circuit, or fuse problems can cause this.
If you encounter such a warning, it is recommended that you check whether the fog lights are working properly and, if necessary, consult a service centre. This ensures the safety of the vehicle's lighting system and allows for the early detection of potential faults.
Why is the Fog Light Symbol Important in Vehicles?
The fog light indicator is an important indicator for ensuring the correct use of lighting while driving. This symbol allows you to easily understand whether the lights are on or off and prevent misuse.
Recognising all the lighting symbols on the dashboard is crucial for safe driving. Incorrect use of fog lights can negatively impact road safety; unnecessary use can dazzle oncoming drivers, incorrect use of rear fog lights can disturb drivers behind you, and excessive lighting poses a risk when driving at night. Therefore, fog lights should only be switched on when necessary.
Front and rear fog lights can be used together, but as the rear fog light signal emits a stronger light, its unnecessary use is dangerous. It is important to only turn on the rear fog light when visibility is severely limited.
Why Are Fog Lights Necessary for Safe Driving?
Fog lights are one of the most important aids for safe driving, especially in low visibility conditions. When the fog light indicator appears on your vehicle, you know that the lights are on, allowing you to drive more safely in difficult conditions such as heavy fog or snow. Using fog lights correctly is critical for both your safety and that of other drivers.
