Now, when car headlights is refitted, xenon lamps are basically installed. However, after the xenon lamp is installed, it is astigmatism, and lenses need to be added. It is recommended to install a double lens. At present, it is more popular to install small Q5 double lens and Hella double lens. Both kinds of lenses are practical. My car used to have two optical lenses modified from Hella, but now I go out to sea to pull three lenses, so I just take the original lens down and install three lenses from Hella. If there is anything wrong with my headlights in Guiyang, I will go directly to the headlights in Qian Ying, where they are more friendly and modified more carefully. If you use angel eyes, I suggest not adding them. That thing doesn't look good. It feels a bit like a BMW.
