If the indicator with the symbol of the rays directed down and left on the dashboard of your car lights up, this is a direct indication of activation. passing beam headlamps. Unlike long-distance lighting, this mode is designed to move in conditions of insufficient visibility with oncoming traffic, so as not to blind other participants in the movement. Modern cars, whether they are Volkswagen Polo, Toyota Camry or Lada VestaThe standardized designations are used, but their color and display method can vary significantly depending on the logic of the onboard system.
Understanding exactly what the passing beam icon looks like is necessary not only to check the state on, but also to diagnose malfunctions in a timely manner. Often drivers confuse this symbol with position lights or fog lamps, which can lead to fines or emergency situations in the dark. Below we will take a detailed look at the visual differences, color coding, and possible electrical issues associated with this lighting mode.
Visual description of the standard symbol
The main symbol for the dipped beam on is a stylized image of the left headlamp with three lines facing downward at an angle. These lines symbolize the light beam that illuminates the road in front of the car without rising above the level of the hood. Most modern instrument panels, including models Hyundai Solaris and Kia RioThis icon is lit in green, signaling the normal operation of the system.
It is important to distinguish this indicator from the high beam symbol, where the lines are directed strictly horizontally. If you see a green light bulb with tilted rays, then passing-beam activated correctly. However, on some older models or in specific configurations, the indication can be made in the form of a simple light bulb without additional beams, which sometimes causes confusion among inexperienced drivers.
In some premium cars, such as BMW or Mercedes-BenzInstead of constant burning, short-term illumination of the instrument scale or a change in the color of the speedometer edge can be used. This is done in order not to distract the driver with bright lights at night, while maintaining the information content of the control panel.
Color encoding and indicator states
The color of the indicator on the dashboard carries important diagnostic information. Green, as mentioned earlier, means normal operation. If the icon flashes, changes color to yellow or orange, this is a signal that the system has detected the signal. faultyness. For example, a burnt out lamp often causes a change in the resistance in the circuit, which is fixed by the control unit.
The yellow or orange color of the indicator usually indicates a partial malfunction. This can be a burnout of one of the passing beam lamps, oxidation of contacts or problems with the fuse. In cars with xenon or LED headlights, such an indication may indicate an error in operation. spark-box Or LED drivers.
โ ๏ธ Note: If the indicator is lit red or accompanied by an audible signal, operation of the car in the dark is prohibited until the fault is corrected, as this creates an emergency situation.
Auto mode (automatic switching on) also has its own characteristics of the indication. In this state, a separate green passing beam icon may not light up at all, giving way to the "A" symbol in the circle or the headlight icon with the inscription "AUTO". This means that the car itself decides to turn on the light depending on the lighting.
Differences from other lighting devices
A common problem is confusion between the icons of different lighting devices. To avoid driving errors, you need to be aware of the differences. Below is a table that helps identify the main symbols in the dashboard.
The position lights are designated by a symbol where the rays are directed in both directions from the central axis, which visually distinguishes them from the directional passing beam. Fog headlights have a characteristic fracture of the beam line down, crossed by a vertical line, which symbolizes a wide and low light flux.
| Type of lighting | Direction of rays | Color of indicator | Characteristics of the symbol |
|---|---|---|---|
| Middle light | Down and left | Green. | Three sloping lines |
| Far light | Horizontally. | Blue | Straight lines |
| Dimensions | Both ways. | Green. | Symmetrical rays |
| Fogheads | Down with a break | Orange/Green | vertical |
Understanding these differences is critical when undergoing technical inspection and daily operation. Incorrect use of lighting devices, such as turning on the high beam in the city, can blind oncoming drivers and create an emergency.
Diagnostics of lack of indication
If you turned the lever or button on the passing beam mode, but the corresponding icon on the panel did not catch fire, this does not always mean a malfunction. First, check if the lights are on. Sometimes the problem lies in the burned LED display on the dashboard itself, especially in cars with high mileage.
However, the lack of panel reaction can be a symptom of a more serious problem in the circuit. This can be a break in the wire, a malfunction of the steering switch or a burned fuse. In modern CAN-bus vehicles, the lack of light can block other systems.
โ๏ธ Checking of the lighting system
For accurate diagnosis, it is recommended to use a multimeter or consult specialists. Self-replacement of lamps without checking the circuit may not solve the problem if the reason lies in the oxidation of connectors or damage to the wiring under the hood.
Features of work in the mode "Auto"
In cars equipped with a light sensor, the control of the passing light is often switched to automatic mode. In this case, the driver does not physically switch the lever to the passing beam position, but leaves it in the "Auto" position. The display on the panel can behave in different ways: the icon may not burn at all until it is completely dark, or it may light up with dim light.
In such situations, the driver must be forced to passing-beamIt is based on traffic rules, not just sensor readings.
โ ๏ธ Warning: Light sensors are often located on a torpedo and can be closed with objects (phone, documents), which will lead to incorrect operation of automatic lighting.
Some models of cars, such as Renault Duster or Nissan Qashqaiallow you to adjust the sensitivity of the sensor or the delay time of the light switch off through the menu of the onboard computer. This allows you to adapt the system to the individual preferences of the driver.
Adaptive passing beam
In modern adaptive light (AFS) cars, the passing beam can automatically turn behind the wheel and change its shape depending on speed and road situation. The indication of such a mode may be supplemented by the message "AFS" or a special symbol on the display.
Frequent malfunctions and their elimination
One of the most common causes of problems with passing light is the burnout of halogen lamps. Despite the ease of replacement, frequent repetition of this situation may indicate voltage surges in the on-board network or poor quality components. It is recommended to use lamps of proven brands, such as: Osram or Philips.
Oxidation of contacts in the lamp cap or in the headlight connector is another common cause of unstable work. Moisture entering the headlight through a broken sealant leads to corrosion of the contacts and, as a result, to the absence of light or flashing of the indicator on the panel. Regularly checking the tightness of the headlights helps to avoid these problems.
If the problem is not in the lamps, you should pay attention to the relays and fuses. In some cars, separate fuses for the left and right side are responsible for the passing light. Their burnout can be caused by a short circuit in the wiring or a malfunction of the current consumer himself.
Tip: When replacing passing beam bulbs, never touch the glass bulb with your hands. Fat marks on the glass lead to uneven heating and rapid burnout of the lamp.
Legal aspects and fines
The use of passing beams is regulated by traffic rules. In many countries, including Russia, movement with the passing light turned off in the dark or in conditions of insufficient visibility is prohibited. The absence of a working indicator on the panel does not relieve the driver of responsibility if the headlights do not burn.
Fines for faulty lighting devices can range from a warning to a monetary penalty. Moreover, a faulty passing beam is the basis for prohibiting the operation of the vehicle until the fault is corrected, which may lead to the evacuation of the car.
โ ๏ธ Warning: Installing non-standard lamps (e.g. LEDs in halogen-based headlamps) can lead to blinding oncoming drivers and problems with the inspection.
Regular inspection of all lighting devices is not only a requirement of the law, but also a guarantee of safety on the road. The driver must be sure that his car is visible to other participants in the movement, and he himself sees the traffic situation well.
Green icon with inclined rays is a standard indicator of passing beam. Blinking or changing color signals a malfunction requiring immediate attention.
Why does the passing beam icon burn if the headlights are off?
This may indicate a circuit circuit closure, a faulty steering switch, or an error in the body electronics control unit (BCM). Computer diagnostics are required.
Can I drive with a lighting dipped-beam error indicator?
Technically, the car will move, but it is unsafe and illegal. The lack of full lighting reduces visibility and can lead to an accident. Insurance may also be denied in the event of an accident.
How often should I change the dipped-beam lamps?
The service life of halogen lamps is on average 500-1000 hours, xenon lamps - about 3000 hours, LED lights can last up to 30,000 hours or more. Replacement is done as the fire burns out.
Does the color of the headlight lens affect the indicator?
No, the color of the lens (transparent, yellow) does not affect the electrical circuit and the indicator on the instrument panel. The indicator responds only to the presence of current and resistance in the lamp circuit.
What if the error indicator does not go out after replacing the lamp?
Perhaps installed lamp with inadequate resistance (often happens with LED lamps without deception). Additional resistors or adjustments through a diagnostic scanner are required.
