That's easy enough: use the pic to drive a relay and wire the relay circuit
to the ignitors... I'm using a 16C84 and a couple of 12V 10A relays to drive
6 floodlights (200W each) around the perimeter of the house. When I had only
one relay (for the back lights) I wired the typical 2N2222 driver. When I added
a second relay instead of adding another 2N2222 I switched the 2N2222 driver
to a 5V relay and drove the 2 12V relays from the 5V one. Speed was an
absolute non issue since the lights only go on and off twice a day.

I suggest using a relay.
