I have around 5 security lights with motion sensor around the house but they are not working, and I couldn't figure out where the switches are. Finally, in the garage I found this timer (attached). I can't think of any other thing in the house can be the switch for the security light, but it seems damaged, because the odds of 5 security lights go bad should be very low. So I guess my first question is, is this thing typically used as switch for security light? If so, what is the best way to troubleshoot this?

This is a very common type timer for light, sprinkler pumps, pool filters, etc. Start out by pulling out the yellow disk and turn it to the current time. Monitor it to see if it keeps proper time. There is an "off" tab still on the disk but no "on" tab. It looks like it might have fallen off and is still in the box. This would prevent the lights from going on. There is also a silver lever that says "on" and "off". This lever is a manual switch for anything hooked up to it and it will over ride the timer so start checking that to see if the lights go on. Then turn off the power and swing that plastic cover out of the way and check the wiring for power. Also check the bulbs to make sure they are good.
