you can use square wave oscillatorIC 555 to turn ON and OFF the LED.

IF you want to vary LED lightning Speed you can add a potentiometer in IC 555 or

you can use Pulse Width Modulation(PWM) circuits to vary lightning speed of LED

Try adding an audio pre-amp to the 555 input.

Then add a Darlington to drive your LEDs.

How are you switching them on and off ? A physical switch ? You'll need a transistor that can handle the current, and probably something like a 555 timer to switch it on and off. You'll have a potentiometer to adjust the flash rate
