| I made some with red ones, and just wired them onto a piece of circuit board, and then added a resistor to get the right voltage to teh lights, if you use enough led's though you don't need the resistor. I'll see if I can find my instructions |

what is the forward voltage? the current you want through them? I have done these for smaller lights, very time consuming but looks good if you take your time. first figure out how many you want in each series branch (by the voltage and current ratings) then just decide how many series branches to parallel together (as many as you want), I usually just use predrilled perfboard (with the copper donuts), break out the soldering iron and go nuts... |

Why not buy some LED bulbs, they are cheap ( about $ 3.50 per bulb ) and they have them in 1156, 1157 and 3156

So wire them like (if i wanted 30 leds)
