I've been looking at modest price off road driving lights for night time beach travel lately and I've gotten advice both for and against Hella 500's - or the Hella's plus an HID conversion. But I remember that back in the day KC lights, with the yellow smiley face covers, were on 4X4 trucks everywhere. So I was wondering how one brand stacks up against the other today. Which one do you think is better and why?
