I am looking for a Whelen Advantedge lens. Color could be red, blue, amber or clear. It needs to be at least 11 3/8” long and free of cracks and major gouges. It can be longer and I can cut I’d down to size. I can wet sand it and polish it up if it’s a bit faded. I need the clear style lens and not the diffused style used over strobe heads. I have an oscillating light to put behind the lens so the strobe style lens wouldn’t work as well. Thanks
