Hardly worth explaining, how important for road safety is quality road lighting. Automobile concerns are constantly working to improve lighting devices in vehicles and offer more and more new solutions to this problem. Lamps for car headlights - a serious link, which is directly related to that, how well the road is illuminated.
Because from time to time car owners need to change the light bulb in the headlight, the question arises: which light bulbs are better? After all, modern industry today offers a wide range of different options. Therefore, it is useful to know their characteristics and understand, what are the differences between them.
When buying lamps, pay attention to the size of the headlight and its geometric shape. Its size also depends on the power of the lamp
The main types of light sources for cars
Headlight bulbs, used in modern cars, divided into three groups:
- halogen;
- xenon;
- LED.
Each of these groups has its advantages and disadvantages, therefore from drivers it is possible to hear opposite responses about the same model.
Light sources are distinguished by the type of base - H1, H4, H7, etc.. Each type also has its own purpose and features.
Type H4 is used for cars, which combine low and high beam systems. It, depending on the voltage, gives a bright powerful beam for high beam or weaker, to illuminate the road directly in front of the car.

H1 is placed mainly on the main lights for high beam. They give a powerful bright beam. Although some drivers use H1 LED lamps for low beam - they do not dazzle drivers in front of cars, however, the quality of lighting in the near area is disputed.

halogen lamps
Headlight bulbs from the first group are the most common - their design is quite simple, and in terms of price and quality, they are considered optimal. Consist of a flask, which is made of carbide or quartz glass, filaments and halogen gas, which is pumped into the flask.
Halogens give an even bright light and provide a good view of the road in the dark. Their cost is reasonable, however, they have a serious drawback - the operating temperature of this group is very high. This has a negative effect on the service life of the product, and can also cause the headlight itself to melt. The second disadvantage is ??they, that due to the presence of the filament such products are afraid of strong vibration - because of it they fail.
The wrong choice of headlight bulb can lead to this, that you will constantly dazzle drivers on the road or, vice versa, the road will be poorly lit.
xenon lamps
Xenon light sources are a modern type of lamp. They have no filament, so they are not afraid of vibration. Glow is due to an electric arc, which occurs between two electrodes in a flask with xenon medium.
The lamps give an even light blue light, which qualitatively illuminates the road and does not dazzle drivers goes towards the vehicle. The disadvantages of this variety are two factors - the high cost and the need to install an ignition unit. Such lamps are placed in the headlights much less often, than halogen.
LEDs
Today, LEDs are considered a promising group of light sources. An increasing number of motorists are paying attention to them. If you carefully study the reviews, you can make a list of benefits, thanks to which LEDs are becoming increasingly popular:
- bright comfortable beam, which does not dazzle drivers of oncoming cars;
- low operating temperature, thanks to which this variety can be used in plastic headlights;
- vibration resistance;
H7 diode lamps for low beam car
When making a decision, which headlight lamps to buy, it is better not to skimp and buy a normal lamp
- temperature unpretentiousness;
- low power consumption helps to significantly save battery power;
- durability;
- beam stability.
Of the disadvantages of LEDs are two significant - the high cost and the need to install lenses to adjust the light beam, because they do not give spot light.
Drivers, which put diode bulbs for cars - H7, H4, H1, respond to them very positively.
Choice of light sources for headlights
The choice of headlight bulbs is very important, and should be taken seriously. Making decisions, which lamps are best to put in the headlights, the following criteria should be noted:
- compliance with traffic rules;
- lighting color;
- brightness and size of the light beam;
- lighting stability;
- compliance with the standards of your machine;
- which lead to overheating of the gasoline or diesel engine.
These indicators will help you make the right decision. However, choosing, which light bulbs to buy, do not marry cheap. It is better to prefer manufacturers, which have established themselves positively in the market, even if you have to pay a little more.
