I recently taught myself how to wire up LEDs and i have put about 35 of them in my car (map pockets and vents) I basically just wired them up and put them into the car and super glued them to hold them in place. So now i want to make some for under the dash and eventually make my own underglow. The problem is i cant seem to find any Lexan tubing locally so i need to get them online. Im not sure what size i'll need but if anybody has had experience in making LED tubes and knows where i can get this stuff at a reasonable price and what size i'll need ( I figure i will need 9 inches for length but as far as diameter i have no clue.)that would be greatly appreciated. Thanks
