I have both KC Daylighter 130w Driving Lights as well as the Long Range.
I would recommend the Driving Lights, as the Long Range are more of a thin long spot light type.
The Driving Lights throw almost twice as far as your high beams.
They are wired with a relay and a switch.
These are not street legal, however if you just use some common courtesy and turn them off when you see on coming traffic, you should be okay.
