14.52. About the correct adjustment of headlights
The correct adjustment of headlights in a bigger measure belongs to culture of driving, rather than to any technical problems. Therefore we will talk about why over time headlights start to give dim light, probably, and sufficient on the desert highway, but absolutely inefficient on recovered, especially, if the counter flow is great.
Sometimes sin on the generator and a tension regulator. There is a grain of truth: malfunctions of these devices are appreciable by the "movement" of a light stream as though submitting to quantity of turns of the engine. It is clear that unimportant operation of the generator and a regulator of tension influences not only on efficiency of headlights – the accumulator, or not receiving a high-grade charge, or, on the contrary, first of all suffers – receiving there is many it, from what the electrolit "boils". Headlights in this case play only an indicator role though superfluous tension strongly reduces a resource of lamps. Continuous dim radiation arises for other reasons: or strongly the reflector becomes soiled or becomes covered by corrosion, or there is a dark raid on an internal surface of a flask of a lamp.
If the durability of a reflector depends on many factors, even quite serviceable lamp "gathers" a dark raid for any 30–50 thousand kilometers. Its efficiency in that case percent on 20 below the new.
The reflector "lives" more long. In modern cars the reflector and glass of a headlight are, so to speak, an integrated whole that first of all provides the most optimum light bunch, and in the second – tightness. The lack of tightness promoted penetration in a headlight of a dust which burned then on a reflector and reduced it светоотдачу. The same occurred and to the moisture which was actively condensed on a reflector that caused corrosion.
About five years ago against corrosion tried to fight in any improbable way, filling in in a headlight red brake liquid. The fashion on this which is rather harmful, rather than passed a useful invention, but there was other extreme – plexiglass "points" on glasses. Besides, that such protection reduces светоотдачу, "smearing" the direction of beams, it causes strong heating and a reflector obgoraniye. What in that case use from the glass protected from stones if the reflector suffers, – it is not clear, as how it was already told, glass and a reflector nowadays represent an integrated whole? By the way, therefore it is no point to buy "lens" separately: good light from such headlight never to achieve.
At last, as to adjustments. Even the most excellent headlights supplied with halogen lamps, can appear on the way useless if they are adjusted somehow. Not everyone and not always has a possibility to make adjustment at the stand. Therefore very quite good results give the old, well tested ways of "house" adjustment. The car establish on an equal platform, measure 30 meters and put on a mark, let us assume, a brick. One of the headlights, included on a passing beam, something veil, and in the second – rotate adjusting screws so that limit of illumination vertically to bring to the put brick. The same do and with other headlight. A driving beam regulate in the horizontal direction, but already without a brick: here it is important to achieve, that bunches from both headlights did not fork and did not meet in the middle.
