This is something that I thought of this year and couldn't find anything that resembled it so I thought maybe there is a manufacturer trolling this forum that would pick up on this concept. ( and the idea is date and time stamped so, call me ) I would love to see a timer system that is controlled from one main photocell timer with the ability to utilize auxiliary switch boxes at the other power sources. These auxiliary switch boxes would then be activated remotely by the main photocell timer. Frankly, I don't know why it hasn't been created yet. It shouldn't be any more expensive than what timers currently cost (I bought a remote controlled switch for my Christmas tree for $10) and it would eliminate any issue with portions of our Christmas displays coming on at slightly different moments. Its a small issue, I know, but it would button up the professionalism of our industry just one step more.
