This is almost the same circuit as the LED Transistor Oscillator circuit, published previously (https://everycircuit.com/circuit/4906943210717184). This circuit uses push button switches rather than a capacitor to switch between the LED's. It's not a particularly efficient circuit as both transistors are always conducting. The circuit uses just over 50mA irrespective which LED is switched on. Try altering the component values to see if you can make the circuit more efficient..
