Help to identify resistor to remove
I guess you should short legs 2 and 3 of Q2. It's the lonely leg and the one to the right on the picture. Try it with tweezers at first, then use a wire. 

My guess is that R6 is a higher resistance for weaker light, and R5 is a 10 ohm resistor for stronger light. But i am not sure, you can use it for long time. It may be dangerous for the led.
