This is what I was trying to say earlier...
Perhaps this is why I can see better with them... More light is not necessarily the best light if more light results in a blinding light instead of a dimmer light that still illuminates the road.
Regarding the filter comments, that makes perfect sense. Having said that, with these lights, isn't it the intensity of the Kelvin rating, not a filter, that gives the light its hue? 8000K HID kits are almost purple, but not because there's a purple filter. 6000K is a bright bluish-white, 5000K being a true white. It was my understanding that the lower the Kelvins, the yellower the light. The higher, the more blue/violet.
But I may be completely confused. Not at all unlikely.
