Additional headlights of a headlight. Additional headlight: the pros and cons
Automotive optics plays an important role withpoint of view of the quality of machine control and security. A traditional set of its components are parking lights, headlights, brake lights and turn signals. And at all it is impossible to tell, that this set is saved and exists in strictly set parametres. In the segment, regular updates occur, the shapes, sizes and even the principles of lamp operation change - it is enough to recall LEDs and xenon. A slightly different approach to the revision of the organization of light offers an additional headlight, which is increasingly included in the basic configuration of models of large automakers.
Arguments in favor of additional headlights
The very idea of installing additional headlights aroseas a means of helping drivers in difficult weather conditions. Improving the light qualities of modern optics only slightly improves the quality of lighting in conditions of rain, snow and fog. And the means of additional lighting in this respect, of course, give only advantages. As a result, the additional headlight covers a large road area, while not having a negative effect on the driving process itself on other parameters.
Arguments against additional headlights
First of all, the introduction of additionalsource of light - this is the financial cost of its acquisition, installation work and further operation. To acquire cheap optics for such purposes is meaningless, since the effect will also be unimportant. And expensive high-power extra lights will affect the power consumption of the battery. Here it is possible to parry arguments about the importance of safe traffic, but does it often, in principle, there is a need to connect this light source? And in this respect, each car owner must proceed from the conditions of the car's operation within its own region. Also it is necessary to answer and to other question - what type of an additional headlight will be optimum?
Additional headlights of a headlight
This option is aimed at usingnight time. As studies show, in the dark, even with the connection of a standard set of headlights, the visual acuity of the driver is reduced by 10%. In turn, additional high-beam headlights compensate for this flaw, relieving the load on the eyes. In fact, conditions close to daylight are achieved. Especially this effect is enhanced in the case of xenon headlights. First, this lighting option provides at least twice the increased luminous flux as compared to halogen lamps. Secondly, xenon spends one-third less energy, which negates the lack of additional lighting in terms of energy consumption.
It is also worth noting a few negativeaspects. If we are talking about xenon, which will be the optimal solution, then we should prepare for significant costs, since it is not cheap. In addition, an additional headlamp with far-reaching lighting may not always be installed due to the limited number of places intended for lamp installation.
Features of additional "close" headlights
Another option to strengthen the standard optics, whichIt is used in cases when the existing lamps do not cope with their tasks and without obvious weather interference. But even in the choice of such a decision, everything is not obvious. The standard problem of motorists who decide to integrate additional dipped-beam headlamps is to find the installation site. Without installation manipulations with a slight change in design is indispensable.
But that's not all. The problem of many sources of near auxiliary light is the absence of clear boundaries for the separation of light. As a result, users complain about the blindness of oncoming vehicles. As an alternative, additional dipped-beam headlamps can be replaced with modular optics. In particular, experts recommend the use of B-lenses, characterized by a clear light-delivery boundary, and sufficient lighting.
Additional "fog lights"
It is the fog lights most completereflect the concept of additional optics. Their function demonstrates a radical difference between the use of one standard light and a combined version - of course, we are talking about operating the car in inclement weather. But to achieve the optimum effect, you should correctly approach the choice of the device. First of all, you can safely avoid buying headlights worth less than 3 thousand rubles. Nothing but attractive design, and at best, they will not provide. Really useful additional fog lights are characterized by a wide-angle light distribution of the beam. And this is the basic rule of choice. Next, you should give preference to models with well-defined upper edges. It is very important that the design ensures the supply of a light stream downward with a large inclined angle. Such a device will minimize the risk of lighting oncoming vehicles.
Installing additional headlights
The high beam is mounted in the front part, asalready said, if there is a constructive opportunity. In this case, they should not obscure the light of the parking lights. From the point of view of control, it is important to ensure the condition that these headlights will work simultaneously with the base high beam and turn off when passing to the near-beam optics. As for the "fog lights", these additional lights are mounted in the front part symmetrically to the longitudinal axis of the machine. Also it is necessary to observe the standard distances - in height the gap will be 25 cm from the road, but not more than 80 cm. In the case of off-road vehicles, such devices should not exceed the level of the passing beam. In terms of controlling the fog-lighted additional optics, it should be noted that it must maintain performance regardless of the main near and main beam.
On the possibility of providing an additional machineoptics it is advisable to think about in the process of purchasing a car. Large manufacturers provide new models with this light, initially optimizing the design of the installation sockets for them. This solution is offered both as a basic option and as an element of extended packages. Also, an extra headlight can be installed on some models that are not focused on similar improvements. But in this case it is recommended to think over except for the technical part and the possibility of on-board electrical wiring. Especially if the lighting equipment is controlled by third-party systems like alarms with access control. As for the justification of this choice, then, with a competent installation, the new headlights are unlikely to lower the safety of driving, and the positive effect will certainly be provided to some extent.
