Infrared LED circuitry help

Would someone please make me a circuit diagram for using 2 separate sets of 3 Infrared LEDs coming from the one power source? It needs to go via an on/off switch (that turns all six on/off) and I need to know things like resistors, power, etc. so I know what I need to have. I just want a simple circuit, nothing fancy. It's just a home project I'm doing and tis nothing exceptionally urgent, I just don't know what I am doing when it comes to circuits (I used to be good at it but haven't done anything in years). The help would be appreciated.

Thankyou in advance

Some of the people here know the voltage requirement of an infrered LED, but none of them know how much voltage you have available or what current you want to put through the LEDs.

Check this circuit. it fits your requirments...

Not a good idea to put the led's in parallel with only one resistor. Use 1 for each set of 3 led's if they are similar to this one.

each resistor should be 120 ohm 1 watt. Or if you are really using 12 volts you can put all 6 led's in series using a 62 ohm resistor. In this case 1/2 watt would be ok.
Best to answer the questions posed in post 2.

Thanks people, going with the diagram and that pdf should help too, thanks again
