I have a Whelen Advantage lightbar with the externally mounted lower takedown lights on the front and flashers on the rear. The lenses are pretty faded and even wet sanding and polishing didn't clear them up. I am looking to replace all 4 lenses if I can find some in good shape. I would be interested in red, blue, clear or amber. The lenses measure 4 1/4" X 1 3/4". Let me know if you have any you are willing to part with. Thanks.
