Increased inspection of the headlights is increasing with the "yellowing and dullness"!How to regain "bright light"

The test criteria for headlights at the time of vehicle inspection became stricter

The current headlight lens of the car is made of resin (made of polycarbonate).While it is light and has the advantage of a high degree of freedom in design, if you use it for many years, the resin will deteriorate due to ultraviolet rays and the like, and the surface will be yellow or cloudy.

This yellowing and cloudiness are old -fashioned, and it is a headache for the owner, but it has become a problem in recent years due to the fact that it has been caught up with security standards and does not pass the vehicle inspection.

This is because since September 2015, the test standards for headlights at the time of vehicle inspection have changed, and the optical axis (the position of the elbow point) and the amount of light have been examined much more strictly than before.If the resin headlights are yellow or cloudy, the elbow points will be blurred and the number of cases will be rejected by vehicle inspection.

Another problem is light.According to the current test, the low beam (passing light) has a standard of 6400 candela or more per light, but if it deteriorates and becomes a yellowed lens, the light is blocked there, irradiating sufficient light.It will not be possible.

The effect of yellowing is enormous!

The loss of light due to this yellowing was large, and there was an example that the headlights of the car that had fallen after the vehicle inspection due to lack of light were polished with chemical agents, but the 2000-4000 candela became brighter, and the effect of yellowing is quite enormous.。

Such yellowing (cleaning) of headlights is a standard menu at car supply stores and dealers, so you can get it back to a clear state for about 3000 to 5000 yen, so the light is a little darker.If you think, you should use these lens cleaning.

In addition, a special chemical agent that takes yellowing of the lens is also available, so it is possible to polish the lens with DIY.It should be available for around 1500 yen at car supplies stores, home improvement stores, mail order, etc.DIY can regain the transparency unexpectedly, so please try it once.
