So I have been thinking over options for wiring up a saber I will be gifting to my brother-in-law. I would like 3 Led's in total: The main green Led and then two accent led's, probably 5v led's I'm thinking. So I have a few questions here.
1. How's the wiring diagram?

2. Do I need / should I have a resistor for each accent Led?

3. What ohm resistor do you suggest?

4. Will this setup drain the batteries even when the off switch is OFF. Opposed to a kill key, I think they are called?

Any help or suggestion will be greatly appreciated, Thanks in advance.
