Lens Filters for Round Long Range Lights

I recently purchased a set of the Cyclops Long Range lights for my KTM 1190. The salesman recommended the filters to me when I called in my order, I was slightly skeptical since I had a set of filters on my Riged dualies that really did not do anything. In this case they really worked well, not only did the lights retain most of the extreme long distance, they made a very nice wide beam with a upper cut off. I find this to be a very nice driving beam, that allows me to see far better than with any other lighting set I have owned. Great product!
