How to dramatically increase the brightness of car headlights without replacing the bulbs in them
According to our car market analysts, the demand for on-board light sources increases noticeably as winter approaches. Because most of the day falls in darkness during this period, they are mainly purchased to improve the light properties of standard headlights. However, drivers do not always succeed in achieving the desired results. The AutoVzglyad portal found out why this happens.

Today there are many car headlights on the market that are distinguished from their “brothers” by their increased radiation intensity. Such devices have long been included in the list of common electrical equipment used by car owners for independent tuning of headlights.

Indeed, such products still sell quite well, which is primarily due to the seasonal reduction in daylight hours, but also to the muddy autumn weather, which significantly reduces visibility on the road. Therefore, the desire of motorists to improve the active safety of their cars, especially under such conditions, can only be welcomed.

As experts note, various adjustments to light sources and options for their installation can be used for this. Some replace the standard halogen lamps with brighter xenon lamps, others integrate more advanced LED elements into the car, while others are satisfied with ordinary halogen lamps, but with much higher luminous intensity. All this, of course, is good, but only if the actual effect of such tuning is really significant.

But as practice shows, it is not always possible to increase the illumination level of the road at night with the help of brighter “emitters”. And this is primarily due to the design features of modern headlight units. Let us remind you that special plastic is used in its manufacture. This is the so-called polycarbonate glass, which has a number of advantages over traditional glass. Polycarbonate is therefore much lighter than the latter and is not inferior in terms of mechanical strength. In addition, it is resistant to various aggressive environments – salt solutions, oils, acid formation, etc.

However, under certain conditions (for example, a combination of high temperatures and regular exposure to a number of organic solvents, including those used in headlamp washers), ‘sores’, cracks and flaking may appear on the surface of the polycarbonate. These plastic defects, even the smallest, lead to noticeable clouding of the headlight at best (photo above). At worst, they become the reason for its failure.

It is quite clear that the clouding of the headlights, which, by the way, is often seen in heavily used cars, significantly reduces their standard lighting performance. Therefore, all attempts to improve them with bright lamps, but without restoring the original transparency of polycarbonate glass, fail in most cases. And to achieve any significant effect, experts say, the surface of the headlight must be highly polished. However, if you do this at a service center, you will have to spend a lot of money.

And according to experienced auto electricians, you can solve the situation with dim headlights yourself. Let’s say, with the help of car cosmetics. The most important thing in this matter is the selection of the right drug and its correct use. Any folk remedies or “life hacks” when repairing the plastic of headlights are extremely undesirable. As for car care products, it is better to take products from trusted manufacturers. For example, headlight polish produced under the Ruseff brand.

Experience with the use of the drug has shown that it quickly removes small cracks and scratches from polycarbonate glass. Along the way, the composition eliminates the characteristic yellowness of headlights, clouding and faded erosion spots that appeared on them during use. The product itself is easy to use: it is easy to apply, dries quickly and polishes well. After this treatment, the “shades” of the head regain their original transparency, significantly increasing the brightness of their glow, without any replacement of lamps.
