    Hello, I am trying to make a small thin flashlight on a breadboard then a circuit board. I do not know a lot about wiring so I want your help. LED's 5 or 6. Watch battery and holder 3v unless something else small? Small switch. I do not know what I need as far as resistors or anything else. Someone help please! I'll buy what I need already bought lights and switch

    we need to know the specifications for the LEDs

    Do you really mean "watch battery"? One (or even several) of those are not going to be capable of delivering much power.

    Do you have a part number on your LED's?
    That will help identify what you need to drive them.
