I am using the following circuit to create a pulsing/throbbing LED effect.
The LED is being driven by the saw tooth generated at the capacitor.
It is working fine, but the problem is, the maximum brightness of the LED is very low. Inspite of connecting a transistor, the LED won't glow to its full brightness. I tried various modifications but nothing seems to be working.
Can anyone please suggest me a suitable mod so as the LED lights up to its full brightness when the i/p signal is at its peak.

EDIT : Just noticed, this is the same circuit
