Aiming Roof Light Bar

I just installed a lightbar on the roof. How is everyone aiming them?

I've seen sites showing to aim driving lights and how to aim fog lights but I can't find anything for roof light bars.

Or is it just find a dark alley and see how it goes?

 

That's what I would think. Just mess with it till it's where you want it, I don't think it's the same for everyone. Once your out and actually using it you might need to adjust a little more to get to your liking.

 

Remember it's not a driving light so there's no reason for it to be aimed like one. You cannot use it on road. Best to flip it on when you are on a long straight road with things bordering it so you can see and aim it wherever you think you need more light.
