I put a 60-1 into a cocktail and everything works great. I added 5 lights (1 coin door, 4 control panel) and they all come on but now my power supply is whining. I used 555 bulbs in your standard bulb holder, daisy chained them, and hooked them up to the +12 on the PS. Is this normal or do I need to change something?

Thanks for the help.
