OK, so I'm going to order some TK-409 chest lights, but I wanted to know 2 things first.
1) I've heard of the acetate stuff that's supposed to go over the board. What color should it be, and where can I get it?
2) Is the acetate supposed to be one clean piece that goes over the whole face of the board and then secured to my chest piece?
Pics will help a ton!
