Hi there guys/gals I have a couple of question's regarding light bars.

To start with I am totally stumped for which brand to buy. I want a quality product that will last. I already have a light bar mounted on the bull bar which is a great white 9 led (just over a foot in length) and it works a charm.

Do they require a roof rack to mount to the roof? or can you mount them to the gutter rail and where can I get them.

also is there much difference between a $500 42" and a $1600 42" price isn't a concern with this as I like to buy a product that's right and buy it once.
