ok, so does this get wired in parallel?

the capacitor and the led

9 volts may kill most LED's instantly! Use a current resistor for .20 ma at the LED voltage.

Resistance = Vin - Vled / .02

Red and yellow LED's need only 1.5 to 2 volts. Bright LED's can use up to 3 volts.

one step short of a flashlight. a "breathe" effect would be more useful.
