I need only the leds and I will design the circuit for them Regards Doron Doron I used 0603 and 0805 smd leds on mine bought via Amazon . com, they are very small and not pre-wired, so you need to have some soldering skills to hook them up. I used 30 AWG coated magnet wire to hook them up Good luck Jean-Pierre
