Dear Friends,

Now that things are working but i've need the second option which can change the LED light manually through switch.. I did not find any solution about that.. looking forward to get he solution from genius.

Thanks in Advance...

You can use a DPDT switch to exchange the NO and NC outputs of the relay before going to the lights. There may be a simpler solution, but this is what came to mind.
