Re: homade led tails (sneak peak)
finally getting around to building these. What is the black stuff you put on the back, and the white stuff you used to space off the Lense?
Also, please help me understand, why you need the 120-ohm resisters. Seems to me as long as you get the correct number of lights in a series, there would not be a need. Also seems all they would do is dim the lighting. What am I missing?
