Not sure what leds those are: they can render the circuit not working, depending what they are.
If you look into how the circuit works, it requires that those diodes (or leds) are sufficiently conducting when the drive goes high. That means that combined, those diodes cannot drop more than 5v (from a 5v arduino), and the resistor should be sufficiently small to allow the conduction.
It also requires that the collector sits higher than the base so the supply voltage - voltage on your load is higher than the base.
You will find that lower voltage drop over the diodes works better. I would have used just one led - two leds add no value in their circuit.
