I need to run 4 slow flashing LED lights, one on each side of the house, as alarm on indicators. The power supply will be solar. I want 5mm diffused , red led's slow flashing like once every 2 sec. Any suggestions how I should do this? and if so, I need a schematic diagram. The power supply will be in the attic and runs to the leds from the power supply will be (2) at 25' and (2) at 35' .
