can some1 take photos of how 2 wire 2 leds to 1 battery like tim did for the led kit in the wire from? i looked at multiple led froms, but i dont get it. 7.2 battery? for 2 blue led? 1 or 2 5w resistor? and what kind of switch would u use if u want 1 switch for both leds? (SPDT)?i read about it but need to see pic THANKS

2 leds on a single battery pack is what iam guessing hes getting at.

I would say one 7.2V battery pack one resistor one switch, wire them in para or series I forget which one.

Put them in series. This is just like batteries. You'll be daisy chaining them...

The amperage is still the same for figuring out the resistor, but your forward voltage has doubled.

Just use ohms law... Voltage across the LED (battery voltage) - LED forward voltage then all divided by your desire amperage (in amps not milliamps).
