The Hella 4000 options are:

My 2 Hella 500s are more of a directional spot light. At about 50 yards they keep a pretty tight beam. So I am leaning towards Cornering beam because its a wide pattern and reaches out to 200 meters. i find that the pencil beams will be useless on a trail with tight turns. Even now the Hella 500s are not very helpful on a trail. I will be doing mostly trail driving, some rock crawling, so I won't be traveling very fast. I want to be able to see everything clearly within 100 yards.
Does anyone have the Cornering beam, how do you like them? Will the euro beam give me a wide enough pattern?
