Xenon is not for do-it-yourselfers
When driving on Polish roads, we can be blinded by a home-grown "mechanic" who himself installed xenon headlights.
When driving on Polish roads, especially at night, we can be blinded by a home-grown "mechanic" who himself installed xenon headlights in his car. 
Online auctions and car accessories stores are full of self-assembly xenon headlight kits that fit almost every car model.
Moreover, such kits do not even require the replacement of the original headlights, in which, first of all, the reflectors are not adapted to reflect such a strong light. The vast majority of these kits do not have the headlight cleaning and self-levelling functions required by law. According to UNECE Regulation 48, all these functions are required for headlamps with a luminous flux greater than 2. lumens.
Polish legislation (Law on Road Traffic and Law on the conditions for the release of a vehicle to traffic) also states that the car cannot be equipped with any non-approved components.
For lovers of stronger light, the only way out is to transfer xenon lamps from the same model, but with factory equipment of this type of lighting, to a car with conventional headlights.
- If a police officer has reasonable suspicions that the headlights that do not meet the specifications may be installed in the car of the vehicle he is driving, he is obliged to send the car for an additional technical inspection and there the diagnostician will decide whether the driver will return the registration certificate or replace the headlights, says the chief commissioner Adam Jasinski of the Police Headquarters.
When installing xenon headlights on their own, the car owner must take into account that if he becomes the culprit of a traffic accident, the direct cause of which is blindness, he will be held accountable.
