The instrument panel of a modern car resembles the cockpit of a small airplane, with each symbol conveying critical information to the driver. Among dozens of light bulbs, a special place is occupied by lighting indicators, since not only comfort, but also traffic safety in the dark or in poor visibility depends on their proper operation. Failure to understand which mode is currently activated can lead to fines from traffic police inspectors or, worse, to an emergency situation on the road.
Many drivers, especially newbies, often confuse the low and high beam symbols, as well as the fog lamp indicators, which are visually very similar. ISO has developed a unified designation system that is used by most automakers around the world, but there are also unique markings for individual brands. In this article, we will look in detail at what the light designation in a car looks like, so that you can instantly navigate how to control the external lighting of your car. auto.
Knowledge of these symbols is necessary not only for passing the theoretical exam at a driving school, but also for everyday operation of the vehicle. Ignoring light bulbs or improper use of lighting devices often causes accidents. Let's figure out what symbols what they are responsible for and how to use them correctly.
Main types of automotive lighting and their activation
The vehicle's external lighting system consists of several independent circuits, each of which has its own functional purpose. The basic mode is low beam, which is used in 90% of night driving situations. Its designation on the switches and instrument panel is a stylized image of a headlight with beams directed downwards at an angle. This one symbol familiar to every driver, but
High beams, on the other hand, are designed to illuminate large areas of the road ahead of the vehicle when there are no other road users ahead. This mode is indicated in blue on the instrument panel, which is a universal standard. Activation high beam usually done by pulling the steering column switch lever towards you or using a separate button, depending on the model car.
In addition to the main headlights, modern cars are equipped with side lights that indicate the width of the vehicle in the dark. They light up constantly when the light switch is on and are often combined with the license plate and instrument panel lights. Correct use of these modes is the key to your visibility on the road.
It is worth noting that in modern cars with the system automatic light (Auto), the driver does not have to touch the switches at all, relying on the light sensors. However, even in such machines, you need to know how to force the lighting to turn on if the sensor is dirty or faulty. Control The lighting system remains the responsibility of the driver.
Interpretation of indicators on the dashboard
When you turn the ignition key or press the engine start button, many lights come on on your dashboard. This self-diagnosis system checks the serviceability of all components. Among them, icons related to light will definitely appear. A green indicator usually indicates that the corresponding mode is activated and works fine.
If you see a flashing light or a light with an exclamation mark, this may indicate a problem with the lighting circuit. For example, a burnt-out brake light or low beam bulb is often indicated by a symbol that is crossed out or changes color to yellow. Owners of group cars VAG (Volkswagen, Audi) and BMW you should be especially careful, since their on-board computers are very sensitive to changes in resistance in the lamp circuit.
⚠️ Attention: If the red or yellow light fault indicator on your instrument panel is illuminated, do not wait to replace the bulb. Driving with a broken brake light or headlight creates an emergency situation and is a violation of traffic rules.
The panel may also display automatic light switch indicators. Usually this is the letter "A" in a circle or the inscription "AUTO". While this indicator is on, the car decides when to turn on the headlights. However, in tunnels or when there is a sudden change in illumination, the system may operate with a delay, so manual control will never be superfluous.
When buying new lamps, pay attention not only to the base, but also to the power. Installing high-power lamps can lead to melting of the headlight lamp and overloading the wiring.
It is important to distinguish between status indicators and power indicators. A green light means the light is on. Red or yellow often means an error. Understanding this color differentiation helps quickly assess the condition systems at one glance.
Fog lights: symbols and rules of use
Fog lights (FTL) deserve special attention, since their designations are often confused even by experienced drivers. There are two types of such headlights: front and rear. Front fog lights are indicated by a green symbol with the rays of light directed downward and intersected by a vertical wavy line. This line symbolizes fog, which they are called upon to break through.
Rear fog lights have a completely different designation - an orange or yellow symbol, where the rays are directed horizontally and are also crossed out by a wavy line. The main difference is the color of the indicator and the direction of the rays. Rear PTFs have very high brightness and are intended only for use in conditions of extremely limited visibility (fog, rain, snowfall).
The use of rear fog lights in clear weather or simply at night is strictly prohibited. Their bright red light, comparable in intensity to brake lights, blinds drivers behind and can cause disorientation. On the switches cars These buttons are often placed separately or are located in the second position of turning the handle.
| Headlight type | Indicator color | Ray direction | Symbol |
|---|---|---|---|
| Front PTF | Green | Down at an angle | Headlight with wavy line |
| Rear PTF | Orange/Yellow | Horizontally | Headlight with wavy line |
| Low beam | Green | Down at an angle | Headlight without lines |
| High beam | Blue | Horizontally | Headlight with straight lines |
Correct Application fog lights significantly increases safety in adverse weather conditions. The front ones illuminate the edge of the road and the side of the road without creating a wall of light in front of the driver, and the rear ones make the car visible to those driving behind.
☑️ Checking lighting devices
Specific designations for different car manufacturers
Although standards ISO are the same for everyone, some automakers are making their own adjustments to the design of instrument panels and symbols. For example, in cars of the brand Mercedes-Benz The light switch is often located at the end of the left steering column stalk, and not as a separate “knob” on the panel, as with most other brands. The symbols remain standard, but their location takes some getting used to.
In cars BMW and Mini A system with a rotary control is often found, where mode “0” means complete shutdown, and position “A” means automatic mode. Some American and Asian brands have duplicate text inscriptions in English, for example, “PARK” instead of the dimensions symbol, which makes it easier to understand for those who do not know graphics well. symbols.
Luxury trims may have additional indicators such as "Dynamic Light" or adaptive cornering lights. They are indicated by additional arrows or inscriptions next to the main headlight symbol. These systems automatically change the beam of light depending on speed and steering angle, providing better illumination of the road when cornering.
⚠️ Attention: In some car models (especially right-hand drive or American-built), the direction of the light beam may differ. When buying a car from abroad, make sure that the light does not blind oncoming drivers, and if necessary, go through the adjustment at the stand.
Studying the manual for a specific car always gives a more accurate idea of the nuances of light control specifically in your model. This is especially true for new models with matrix LED optics, where the operating logic can be complex.
What is matrix light?
Matrix headlights consist of many individual LEDs that are controlled by a computer. They can turn off individual segments of the beam to avoid blinding oncoming drivers, leaving the rest of the road brightly lit. This is the technology of the future, which is already available in many new cars.
Typical driver mistakes when controlling lights
One of the most common mistakes is using rear fog lights as regular markers or brake lights in clear weather. Drivers often forget to turn them off, and the bright red light greatly irritates rear traffic participants, causing them to slow down or flash their hazard lights. This creates a nervous environment on the road and can provoke aggression.
The second common mistake is driving with high beams on in populated areas. Many drivers forget to switch gears when approaching a city, or they think that if there is lighting on the road, then their high beams do not bother anyone. This is a gross violation of the rules, which leads to the blinding of pedestrians and other drivers. The blue indicator on the panel should always attract your attention.
The third mistake is ignoring burnt out lamps. Driving with only one working headlight or a “one-eyed” brake light makes the car difficult to distinguish for other road users. In addition, this is a direct path to a fine. Modern optics require careful handling, and replacing a pair of lamps immediately after one fails often extends the life of the second.
Also worth mentioning is the "light greeting" bug. Although flashing your high beams to warn of police or greet an acquaintance is common, in some situations it may be considered obstructive. Use light signals wisely and only for their intended purpose. Traffic rules.
Constantly turned on rear fog lights in clear weather is a sign of an inattentive driver and a reason for cars behind to create an emergency situation.
Legal aspects and penalties for misuse
The Code of Administrative Offenses clearly states the requirements for external lighting of a vehicle. Driving a car with faulty or missing headlights, as well as with dirty lighting fixtures at night or in poor visibility conditions will result in a warning or a fine. Inspectors pay special attention to the work brake lights and direction indicators.
Using external lighting devices for other than their intended purpose, for example, using xenon in headlights that are not intended for this purpose, or installing high-power lamps, can lead to the deprivation of a driver's license for a period of 6 months to a year with confiscation of the devices. This also applies to the installation of colored lamps (blue, green, red) in the headlights, which is strictly prohibited.
It is also prohibited to drive with high beams on in populated areas, if the road is illuminated, or during oncoming traffic. The fine for this violation is usually 500 rubles, but the risk of blindness and an accident is disproportionately higher than the amount of the fine. Compliance with the rules for using light is a matter of not only law-abiding, but also basic driving culture.
Regularly checking your lighting fixtures should become a habit. Before a long trip, be sure to walk around the car and check everything. lamps, wipe the headlights and make sure they shine symmetrically. It takes 5 minutes, but can save a life.
Wipe not only the outside of the headlights, but also ensure that the inside surface of the lampshade is clean when replacing lamps. Dust and greasy stains on the glass from the inside can reduce the brightness of the light by up to 30%.
What does a flashing green turn signal mean?
A flashing green light (left or right arrow) on the instrument panel indicates that the turn signal is on. If the arrow blinks at double frequency (very quickly), this means that one of the turn lamps has burned out or the contact has come loose. External lights need to be checked.
Is it possible to drive during the day with the headlights on?
Yes, according to the traffic rules, during daylight hours all vehicles must have daytime running lights (DRLs) on or, in its absence, low beam headlights. This increases the visibility of the car on the road and reduces the risk of accidents.
Why is the (fault) light indicator on?
An illuminated malfunction indicator (often a yellow light with an exclamation mark or a crossed-out headlight) indicates a problem in the lighting circuit. This could be a burnt-out lamp, oxidized contacts, a faulty fuse, or a problem with the light control unit. Diagnosis required.
How to properly adjust headlights?
The headlights are adjusted at a special stand in the service center or independently at a wall with markings. It is necessary to place the car on a flat area at a distance of 5-10 meters from the wall, load the tank and driver’s seat, and use the screws on the headlight to set the cut-off line according to the instructions for your car model.
What is the difference between headlights and DRLs?
Side lights have low brightness and are designed to indicate the width of a stationary or moving vehicle in the dark. Daytime running lights (DRLs) are significantly brighter to be visible during the day and use less energy than low beams. Using side lights instead of DRLs during the day is not effective enough for safety.
