That is a good suggestion. But I fall into the camp. "Not really that important now." At least not to get me to pull it out of the rack. :-) The little LED are pretty bright and I remember some broadcast equipment used light pipes. OK now I am going to get silly but this is time-nuts. I think light pipe and fiber optics are two different terms. Yes they both pass light. But a fiber optic is a precision glass or plastic waveguide. A light pipe is a bulk piece of plastic that is not a wave guide in respect to the accuracy of the walls. Oh I am so doomed now that I said that. Regards Paul WB8TSL
