What are the benefits of Valeo's double light?

Valeo's lens is not bad, but each lamp factory's dual lens has its own patented dimming technology. Valeo's dimming motors (Cayenne and Triumph) have too many modifications-no one likes to use them, which is why they are not wanted. It is not that its effect is rubbish, but that it is too difficult to install FLO [s:4].
