A lot of vag cars including skoda have "projector" headlights, which use a lens like a projector. A lot of these are fitted with a shutter system to provide high/low beam operation. The shutter simply cuts off the beam pattern for dip. This high tech nonsense means that 50% of the bulbs output is lost on dip, and the cutoff is sharp which as gb pointed out actually makes visibility worse. And as it uses one bulb only means that when it blows you dont have the option of using the other.
A lot of xenons use a similar shutter sytem I think.
Lights are much much better when they have two separate lights for low and high beams, ideally a with a well designed reflector in both cases. Maximum light on the job with a softer cutoff. Basically avoid cars using this shutter system.....
Unfortunately, fashion is leading to stupid tiny designs which cant match a larger one.
And on another note, the use of led drl strings in conjuction with headlights even at lower luminosity is a major road safety hazard.
Fashion over function, bah....
