If your right side isnt lighting up solder a wire between the place where wire 8 is attached to the PCB and the LED

lol @ stupidity with electronics!


how can u be suplying power to something if u solder 1 wire to 3 legs!
if it only needed one wire.. they would only make a 1 wire LED..
but since it needs a minimum of 2.. they made 2 legged LED's and in this case 3 legs!


Leg 1 = Positive
Leg 2 = Ground / Negative

in a 3 leg LED

Leg 1 = one color of the 2 colours (that the LED supports)
Middle Leg = ground / Negative
Leg 2 = the other colour of the 2


cheers

soo witch wires do i use i was gaing to put the led all the way in the hole and solder 3 wires under neath and solder it to the yellow wires thats underneath at the solder points but what number wires do i use to power it. And also the said you can use the one thats working and jump the wires from it but if you do it that way would i only have the same color as the side that is working and the rest of the wires thats on the other side it will not go to nothing is it safe to have all power on that one side will i have to put a resistor on it.
