I have a trophy ridge sight I love it, had it for two years, I have one problem now though, I would like to light the pins up, but do not have a place to put nitro to light it, any suggestes how to light the sight. I have the 5 pin and did not come with any lighting system and I do not want to buy another trophy ridge sight. There is a open space on the under side to drill a hole a maybe put in a light in there. Any suggestins would be great.
