Increase the distance and view angle of a flare

I have some flood lights in my stadium. I am trying to give them a flare effect. The problem is from certain angles the flare isn't visible on the camera, and the camera distance is quite short before the flare disappears.

Is there anyway to increase the distance of the flare effect, and a way to show the flare no matter the viewing angle?

Or is there a better way to do this?

Thanks
