I never have any issues with my little rice rocket that gets driven regularly in very hilly Missouri. The low beams have a perfect cutoff as to not blind oncoming traffic, and then I have a high beam to fill in. I get off work from one job at 10PM and start my second job at 11PM so I drive it at night quite often. It does get the trailer treatment to shows though along with the bike.
Don't mind the crap fitment with the winter wheels/tires.
All I know is, unless I put on the high beams, when ever I go up or down on a hill, the distance to see forward is cut down severely compared to any halogen light setup in a similar hieght car. I fully understand why the cut off is there and thus is the issue with HIDs over all unless they are in auto-adjusting housings( big $$$$$ option) but they do make the very best HID performance. The BMW adaptive HID setup makes the Hyundai lights look like a dollar store pen light in coverage forget the quality of the light itself. No issues at all with hills etc.
I love having bright crisp light not just for driving but in handheld and weapons mounted it is just one of the quirks when it comes to use in on streets in hilly area especially in the country.
I guess is someways maybe even a combo of light tech is the ideal setup even in a low beam coverage scenario.
The best aftermarket HID setups I ever saw performance as well as ascetically pleasing was using IIRC ones from a 2013 BWM adaptive HID headlight retro'd to fit into a housing that fit a Chevy 3500. I looked but I can not find the pic I took.
Some of the new brake lights are cool to where the light intensity goes up and down with the amount of brake pedal force so you know how hard the person in front you is stomping on the brake.
Anyways back to the subject matter.
