Actually, noise is exactly what I plan to use mine for!

I found a remote control traffic light kit and may eventually buy one for this particular signal. There's an old light that flashes in the youth center where I run Macs4Kids each month so I may ask to look at that one for the purposes of wiring and mounting. If something goes wrong, no need to fear--I bought two signals so I would have a spare/backup. Hopefully I don't need to use that; would make a mighty fine rec room decoration.

My proposal for the light:

Green: The students may talk, work cooperatively, etc.

Yellow: It's time to wrap up. Time to stop talking and get quiet for the red light.

Red: All talking must stop. All eyes must be on me, directions will be given.

I plan on using this for a number of things--morning arrival, indoor recess, centers, cooperative learning experiences during lessons, etc.

If I really wanted to get creative for centers, I could get one of those green arrow segments and put it on my signal for center rotation!
