I picked up a pack of five Truglo fiber optic rods. Each was 5" long and in five colors. The colors are red, ruby red, green, yellow, and light orange. The pack has a stock number of TG05C and is 0.060" in dia.

I was able to hold all five colors side-by-side and I choose to use the orange. I can see it better in dim light. It doesn't disappear in the dim light like the red and green do. In dim light it acts like a regular white dot. I can see it because it is light in color. I'll post photos when I can.
