The question is, What lights to turn on during the dayIt is often controversial among drivers, especially those who rarely travel outside the city or have recently obtained a license. On the one hand, natural lighting seems sufficient for confident driving, on the other hand, the statistics of the accident indicate the opposite. The inclusion of lighting devices in the daytime is dictated not by the desire of inspectors to write a fine, but by the severe need to increase the visibility of the car on the road.
Many motorists still forget to activate lights, relying on automatic systems or bright sun. But even in clear weather contrast The car against the background of asphalt and the environment may not be enough for other participants in the movement to notice its approach in time. This is especially true when the sun shines in the eyes of an oncoming driver or when the car moves in the shadow of buildings and trees.
Modern cars come with different lighting systems, and it’s important to understand the difference between them. It's not just a matter of comfort, but duty and a matter of personal safety. In this article, we will discuss in detail what devices you need to use, what mistakes drivers most often make and why you should not save on this.
SDA requirements for the use of light in the daytime
The rules of the road clearly govern when and how lighting should be used. According to the current legislation, in the daytime all moving vehicles must be included. daylight headlights passing beam. This requirement applies to all types of roads, including populated areas and country roads.
It is important to note that the use of other lighting devices, such as fog lamps or position lamps, as a substitute for daytime running lights is not allowed. Dimensions are too low brightness and do not provide sufficient visibility of the car in front, and fog-fog They are designed for use in reduced visibility and can blind other drivers in the bright sun.
⚠️ Note: Using dipped-beam headlamps instead of DRLs leads to increased fuel consumption and accelerated wear of lamps, but is a completely legal way to comply with traffic regulations.
If your car is not equipped with automatics, the driver must independently control the lights. It’s easy to forget about it, especially after a long parking or night trip when you’re used to a certain headlight mode. Therefore, developing the habit of turning on the light immediately after starting the engine is a key skill to comply with the law.
Difference between DRL, passing light and dimensions
Understanding the technical differences between the types of lighting helps to avoid fines and problems with the electrics of the car. Daytime running lights (DWL) These are special lighting devices located in front of the car. Their main task is not to illuminate the road, but to make the vehicle clearly visible to other participants in the movement.
Unlike DHO, passing-beam They are designed to illuminate the roadway in the dark or in poor visibility. They have a more complex light distribution system, so as not to blind oncoming drivers, but at the same time provide a good view. When switching on the passing beam, the taillights usually light up, which is an additional plus for safety.
The overall lights, or simply "sizes", have minimal brightness. Their goal is to indicate the dimensions of a standing car or a moving one in conditions where the main light is no longer needed, but visibility is limited. During the day, their brightness is not enough.
Why is DHO brighter than the size?
Daytime running lights are designed to be visible even in bright sunlight. Their luminous intensity is much higher than that of position lights, and they have a scattering angle directed forward. Dimensions, being included in the day, are simply lost against the sun.
Modern LED technologies have made DRLs very energy efficient. They consume minimal electricity, hardly heat the headlight and last for years, while incandescent lamps require more frequent replacement.
Automation or manual mode: which is more reliable
Most modern cars are equipped with an automatic lighting system. The light sensor analyzes the external conditions and decides when to activate the headlights. This is convenient and relieves the driver of excessive load. However, relying on electronics is not worth it.
Sensors can become contaminated, taped or simply fail. In addition, automation does not always work properly at dusk or when entering a tunnel, where a split second delay can be critical. The driver should always be ready to take control of the lighting.
- 🚗 Automatic mode.: convenient for urban driving, but requires periodic checks of the serviceability of sensors.
- 🔦 Manual control: gives full control, allows you to turn on the light preventively, for example, in rain or fog.
- ⚙️ Combined approach: the use of automation with mandatory visual control of the operation of devices.
If your car is not automatic, develop a reflex: started the engine – turned on the light. Many drivers use the position of “auto” on the light switch, if it is provided by the design, which is the optimal solution.
If you are changing to a rented or new car, be sure to check the location of the light switch and the presence of automatic mode before driving.
Impact of lighting on safety and visibility
Statistics of road accidents are inexorable: cars with lights on get into accidents much less often. This is because the human eye responds better to a moving light source than to a reflected object. This is especially true for motorcyclists and owners of dark cars.
In a city where there are many distractions – advertising, pedestrians, other cars – the visibility of the car falls. The lights on create contrastingThe brain of other drivers reads faster. This gives an extra split second to the reaction, which often saves lives.
Special attention should be paid to driving in the off-season, when the weather changes quickly. Gray sky, drizzling rain, fog - in such conditions, a car without light becomes almost invisible. Even if you think you can see well, for the driver driving towards or in a passing lane, you can merge with the background.
Lights turned on during the day reduce the risk of head-on collisions and re-engineering accidents by 10 to 15 percent according to various road safety studies.
Fines for violation of lighting rules
Failure to comply with the requirements for the use of lighting devices entails administrative responsibility. In Russia, for movement in daylight hours with lights off or DHO is a fine. The amount is small, but with repeated violations or in combination with other misconduct, it can become a nuisance.
Traffic police officers have the right to stop the vehicle for inspection. If it turns out that the lights are not on, and the automatics did not work or were turned off, the driver will be issued a decree. It is important to understand that excuses like “forgot” or “not noticed” have no legal force.
| Violation | Article of the Cao | Penalty amount | Security measures |
|---|---|---|---|
| Movement with headlights off during the day | 12.20 a.m. 1 1 1 1 | 500 rubles | Warning |
| Failure of lighting devices | 12.5 a.m. 1 1 1 1 | 500 rubles | Prohibition of exploitation |
| Use of external lighting devices for other purposes | 12.5 a.m. 3 | 3000 rubles. + disenfranchisement | Disbarment of rights 6-12 months. |
In addition to a monetary fine, a malfunction of lighting may cause the vehicle to be detained until the fault is corrected, if the inspector deems it necessary. Always check the lights before a long trip.
Technical Failures and Their Remedy
A frequent cause of lack of light during the day is not forgetfulness, but technical malfunction. Burned lamps, oxidized contacts, problems with fuses or control unit - all this can lead to the fact that the headlights will stop burning at the right time.
Modern cars are often equipped with a self-diagnosis system that reports the lamp on the dashboard burning out. However, in older models or in the case of DRL, such an indication may not be available. Regular visual inspection of lighting devices is the responsibility of every driver.
☑️ Checking of the lighting system
If you find a fault, do not postpone the repair. Replacing the lamp is a cheap and fast procedure, and driving with a broken light creates an emergency situation. In some cases, the beam may need to be adjusted, especially if the headlamps have been replaced or mechanically affected.
⚠️ Warning: When replacing lamps, never touch the glass bulb of a halogen lamp with your bare hands. Fat traces will cause the lamp to burn out quickly due to uneven heating.
Recommendations for operation in different conditions
Although the rules are the same for everyone, the approach to lighting can vary in different conditions. In a city with its dense flow and many light sources, the brightness requirements of the DHO may be less critical than on the track. The “see yourself – let yourself see” rule always works.
In bad weather conditions – rain, snow, fog – daylight alone may not be enough. It is necessary to include passing-light and, if necessary, fog lamps. This will not only help you see the road, but also make your car visible to others at a greater distance.
Do not forget about the cleanliness of lighting devices. Mud, stuck insects and road dust can reduce lighting efficiency by 50% or more. Regular washing of headlights is not only aesthetics, but also safety.
How do you extend the life of lamps?
To keep the lamps lasting longer, avoid sudden temperature changes. Do not wash hot headlights with cold water immediately after your trip. Also monitor the condition of the wiring and contacts to avoid voltage surges.
To sum up, we can say that the question “what light to turn on during the day” has an unambiguous answer: the one that makes you noticeable and corresponds to traffic rules. Whether it’s automatic DRLs or manual passing lights, the main thing is your safety and the safety of others.
Do I have to turn on the lights in the tunnel during the day?
Yes, I will. The tunnel is an area with artificial lighting and regulations require the lights to be switched on when entering it, regardless of the time of day. This is necessary to adapt vision and designate the dimensions of the car in a confined space.
Can you drive with only the back lights?
No, you can't. The rear lights (dimensions) are not intended to indicate the car in front. Movement with only the taillights on is equivalent to movement with the lights off and is punishable by a fine.
What to do if the DHO lamp is burned out?
The lamp should be replaced as soon as possible. If replacement is not possible immediately, turn on the dipped-beam headlights to meet traffic requirements. Driving with a faulty lighting device is prohibited.
Does the lighting on affect fuel consumption?
The impact is minimal. For modern generators, the load from the lamps of the DRL or passing beam is insignificant and is a fraction of a liter per 100 km of run. Safety is worth it.
