Can anyone please suggest me a plausible solution for this:

a circuit is to be designed where two series connected LEDs are to be controlled by a 2N9303 transistor with a 12V supply and V break downn = 5V. The diode current is to be approx. 15 mA.

What do you mean by the break down voltage?

This is serious: what color are the LED's?

The schematic would be very useful.
