Or how to achieve the most effective illumination
Let's talk about why in due course headlights start to give dim light, probably, and sufficient on deserted highway, but absolutely inefficient on recovered, especially, if the counter stream is great.
Sometimes sin on the generator and a pressure regulator, in it there is a true share: 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 work of the generator and a regulator напрядения influences not only on efficiency of headlights – the accumulator, or not receiving a high-grade charge first of all suffers, or opposite – receiving it is a lot of it, from what the electrolit "boils". Headlights in this case play only an indicator role though superfluous pressure strongly reduces a resource of lamps. Constant dim radiation arises for other reasons: or strongly the reflector becomes soiled or becomes covered by corrosion, or the internal surface of a flask of a lamp becomes covered by dark touch.
If the durability of a reflector depends on many factors about which we still will talk even quite serviceable lamp "types" a dark touch for any 30-50 thousand kilometres. Its efficiency in that case percent on 20 below the new.
The reflector "lives" longer. In modern cars the reflector and headlight glass are, so to say, an integrated whole that in the turn first, of course, provides the optimal light bunch, and in the second – tightness. The tightness lack promoted penetration in a headlight of a dust which then burnt on a reflector and reduced it всетоотдачу. The Same occurred and to a moisture actively condensed on a reflector that caused corrosion.
About five years ago with corrosion tried to struggle in any improbable way, filling in in a headlight a red brake liquid. The fashion on this, is faster harmful, rather than a useful invention has passed, but there was other extreme measure – плексиглазовые "points" on glasses. Besides, that such protection reduces светоотдачу, "smearing" a direction of beams, it causes strong heating and обгорание a reflector. By what in that case use from the glass protected from stones if the reflector – not clearly suffers, especially, as it has already been told, glass and a reflector nowadays represent an integrated whole? By the way, therefore it be no point to buy "lens" separately: good light from such headlight never to achieve.
At last, as to adjustments. Even the perfect headlights supplied галогенными with lamps, can appear on the journey useless if they are adjusted somehow. Not everyone, and not always has a possibility to make adjustment at the stand. Therefore rather quite good results give the old, well tested ways of "house" adjustment. The car establish on an equal platform, measure 30 metres and put on a mark, let us assume, a brick. One of the headlights, included on a passing light, something veil, and in the second – rotate adjusting screws so that light exposure border vertically to bring to the put brick. The same do and with other headlight. A headlight regulate in a horizontal direction, but already without a brick: here it is important to achieve, that bunches from both headlights did not fork and did not converge in the middle.
