I have a question. I want a bulb to glow if the supply is 14 volts and if the supply goes to 7v or lower, the bulb must not glow. Is there any way to do that.
Thanks
Thanks
A """"normal"""" 12v bulb in a car can be a 4w bulb or a 75w+75w bulb. Not a lot of difference, just that one will need a circuit that can handle 350mA, and the other 12.5AA normal bulb of 12v. I mean it must light when the supply is 12v to 14v, but when the supply drops from 12v to 6v or 7v, it must not light. Any kind of single point bulb which are used in cars. The exact watt is not known to me.
