I like that they have no gap... or at least seem not too. But the pictures of the ones i used also show no gap... I would just have hated to spend 100 more for them and end up with the same issue. I could have always put mine inside the light housing and started farther back like this kit as well. I like this set. I was just trying to say is it worth the extra 100 to get them. It wasnt for me.. might be for others.
