Light Flasher Script Box

There are three scripts in this box, one for the parent, one for the child(s)

Put the master script in your controller prim, you will click this one to turn it on and off.

Put the Child #1 and #2 in alternating bulbs (or any combination you want) to have them flash against each other.

These scripts will never go out of sync of each other, but be warned too many "bulbs" will start causing lag.
