No, do not put the resistor on an input leg. It wants to be on the output. The circuit diagram he shows is not what he builds. He's right he doesn't know much about electronics. He says you'd be OK at 16V. The leds wouldn't last long, they are 12 V strips, you could expect minimum 1.2 V drop across the bridge so the max voltage is 13.2 if you want the leds to last.
