Hi all, first great site! I have a question that I need to seek the experts out there to find out how to make something. I need a device that can measure the voltage of a 12v electrical system and supply a ground or positive signal when voltage drops to a certain value. I need to be able to have a low wattage halogen lightbulb turn on when the voltage supplied to it has dropped to 10.5 volts. but have it NOT be lit when the voltage is above 10.5 volts. Is there such a part that I can purchase to make this work... or would it be easy enough to create from low cost parts on line or at my local Radio Shack?
Again, great site... and any help would be greatly appreciated!
