This discussion is had at campsites all over the country as new riders/drivers enter the scene...we can be thankful they aren't going out with stock lighting.
Proper lighting costs $$, works with your eyes and your vehicle speed, brightest isn't always best.
Each light segment should be switched indivdually so you can have a wide-driving on in a canyon and not blind yourself with your spots hitting the walls in tight quarters. Same when you are running higher speed in more open country; cut off the wide driving and hit the hi speed spots to see what is important right then.
Quality lights dont have "hot-spots" "dark areas" or "bright spots" that mess with your vision.
The Chinese versions are bright, use more power per lumen, and splash glare all over. They can get you out to a cool hill at night if that is really all you want, but stick to that not trying to be a throttle-jockey because it won't be as safe or fun.
The light bars above the front edge of the roof are good as Daytime Running Lights (DRL) but the glare factor after dark is a serious problem. A-pillar pods and shock tower bars are better suited than the roof bars.
Spots should be as high as possible and driving or wide driving take the lower placement like front bumpers.
Yes, I like lights and run after dark.
