How to power some Illuminated Pushbuttons

Red is 5v not 3v.

As you said though you want to be using the yellow 12v cable. If you are using the 14v bulbs im afraid they will never be as bright as they should be.

Well right now I was just using the 14v bulb that came with the buttons.   I wasn't aware that the red was only 5v.  That would definitely affect the brightness.  I will try out the yellow cable, I'm sure that will help out immensely. 

The LEDs that I purchased are some 6v and some 12v ones.  I wanted to sort of sample them all.   They have resistors in them, so it's my understanding that I would be able to use the yellow cable for all of these.  The reason I would be ignoring the red cable all together is because if thats only 5v and the lowest LED is 6v, I might as well use the 12v line and let the resistor do its magic. 

Anyway, I will play around with it.   Thank you for the help!
