i had more than enough wire for mine. i actually had to zip tie some at the bottom of my car where it was hanging. mine were VERY easy to hook up. the directions explained every single thing. i can turn mine on with a switch that goes into my car. mine are just hooked to the battery. and than their is also a fuse that came on them. i don't have pictures yet. its too cold to take pics and my car is a dirty wreck right now. but its very easy. i'm sure you'd be able to understand the directions. as for more light, if my headlights are off than they are very bright and it looks like my headlights are kinda on. but when my headlights are on and i turn them on, i can't really tell too much of a difference. probably cause they are pointing more on the ground than straight ahead. but yeah, it gives more light.
