I'm sure not many will agree here, but apart from looking really cool, the visibility advantage of xenon lights over the conventional halogen is at best dubious to me.

This is especially true on unlit, curvy two lane roads with some traffic where you need a good range from your low beam. The bottom line is that no matter how bright your light is, its range is strictly limited by the need to avoid blinding the oncoming traffic. So at some level, the brighter your beam, the sharper the cut-off has to be.

And because your eyes adjust to the brightest part of the vision, I find that it is actually a lot more difficult to see things just around the area of cutoff with the xenon, than it is with less bright, smoother cut-off halogens. But that's also where I really need to be able to see to avoid hitting things.

I'm sure this will not change anyone's mind, but if you for some reason didn't get the xenon, at least consider the possibility that you might be able to see better on some roads.

Now for high beams, there is no comparison. Xenon all the way.
