Lighted doorbell and resistors or diodes
	
	
		Hi, I make ceramic doorbell surrounds and provide a lighted button to go with. I have questions from customers about the lighted button causing problems with their chimes when the chimes play multiple tunes. I've had electrician customers tell me you just need to add a resistor from the Radio Shack. I'm not an electrician and I don't know what to tell people who want to know what ,exactly, they need to get from Radio Shack and how to hook it up. Can anyne help?
