Power supply 12 Volt. 20% kam yada kar sakthe ho. 5 led for one side, dono side k liye 5+5=10 LED. Dono side circuit diagram same to same hi hai.

I have used every two led in series line. So two led = one led. But if you want, you can use only one led for one pin out.
Circuit diagram please

Use only Red LED. And Resistance value also be lower.
