What I'm trying to do is take a piece of plexi and etch some logo into it, and then I want the logo to be lit up from led lights. The question I have is if I simply drill holes in the plex and place the led inside will it work? What direction does the led have to face? should the rounded end point directly into the plexi as if the hole were drilled into the end (thin side) of the plexi? or is it better to have the led's go into a hold drilled thru the plexi so the round end of the led sticks out of the hole? Hope that makes sense. Thanks!
