Has anyone found a good sight, or product that works well in low light situations?

I do have a peep, but it seems big enough that I can pick out my pins, but as darkness comes, I lose my pins before legal shooting.

I see that Tru glow has a small light, for lighting the pins. Has anyone tried this?

Do any sight manufacturer sell lighted pins?
