If you want a couple light to put on top that are crazy bright you should check out Baja Designs new Squadron lights.
I got 4 of them and could not believe how bright they are compared to my stock Can Am Commander lights. Four BD Squadron (Spot) lights can cover a very wide area but even with two you can cover a area big enough to drive as fast as you can.
The lights can be mounted just about anywhere and you can wire them up to a basic switch on your dash. I used two relays for the four lights but you can wire the light direct to power off a fuse.
