ARDUINO UNO, RELAY AND LIGHT BULB

Thank you Don. I have tried the LED, works fine. I need to make the lights work, and I know the first picture does not agree with the relay below, it was for reference. I am building the circuit shown on Hobby Robotics » Using Relays with Arduino – Turning on the Lights, with the relay shown on my picture. And I am taking precautions, thanks for your observations. I need this to work, is for a project in school. After it does, I'll put it in a box with the powerswitch tail you suggested, I actually have one, but that is going to be used after the whole thing is in a box.

That's why I need suggestions for it to work.
