The principal reason I installed mine is to be more visible to traffic during the day for safety reasons. Night vision is vastly improved but I really don't ride at night much. I installed it on my hi-beam only because the basic limitation on a HID conversion is that there are no HID arc capsules that have a transverse (side-to-side) arc path. They're all front-to-back. So H3 lo-beam projector lights should not be converted because the resulting light pattern will be incorrect causing glare to oncoming traffic. My hi-beam pattern is very good with no hot spots or scatter.
Here's a picture comparison of the 55 W low beam and the 35 W HID high beam using the same exposure.
