im not real good with this electrical stuff. everytime i wire something i get shocked or burned. anyways... i was wonder if i could wire leds like this

------+----------+-------+end
-----(-)---------(-)-------(-)end

and not make it loop back. i just want it to be one straight line.

i think you can do that just dont have the two ends [and wires] touching.

Here...
This place lays it out nice and simple.
