How can I use this circuit to make a firework lighter?

Here's the link: www.electronickits.com/kit/complete/elec/ck1607.htm I want to use this part to make a sound activated firework lighter. Please list steps and materials.

It says it has a connection for a relay...I would get that size relay and connect it so that the relay turns on and fires a model rocket ignitor.

The best thing I can think of is to add a few 6 inch-ish leads from the LED, and add a VERY thin gauge of nichrome wire. Otherwise, add a small transformer, then a small bit of nichrome, then ALOT of resistors! to bring the voltage down to whatever the LED would give off. -PKT
