Subject: Piezo Ignitor to power an LED -- any ideas?

I've got this half-baked idea to use a piezo ignitor to power an LED
which needs 2.5v at around 15ma to 20ma. I'm currently under the
impression that my piezo ignitor and piezo ignitors in general put out
micro-amperes of power, at around ten thousand volts or more. I'm
wondering if it's possible to step down the voltage to 2.5v to briefly
power my LED, or possibly charge a capacitor which will power the LED
over a short period of time. If it is possible, how would I go about
I believe a running shoe was manufactured at some point that had
little flashing LEDs which were powered by a piezo ignition like I'm
speaking of, but I can't for the life of me remember who made them.
Thanks in advance for any help.
