Space Between Bumper & HL's

After installing Spyder Halo Headlamps we now have a significant space between the bumper and the headlamp itself. So now we have a 2 inch space that goes from inside (base of triangle) to the outside (point of the triangle) and it is hideous. Should I try to add something to cover the hole and if so, what? Or should I try to find a new bumper?

Thanks!
