I was wondering if anyone knew of a Seven Segment LED which can been seen in daylight.

I have been asked to build a Timer for hours and minutes for tee ball games. I would like to have the numbers fairly large so they are visible from a distance and bright enough as well.

I have looked at 5 inch and 7 inch but not sure if they can been see outside. I only need three digits.

Or is there another more visible solution for the digits.

Just thought I would ask and see if anyone had done this already. I feel I can do the hardware once I come up with the best solution for the digits.

Thanks in advance.
