Hi Craig, dunno if you are aware, but there are relays available that operate at 3.3v with isolation protection (to protect the Pi). They are available at RPiWare.com. These boards are designed specifically for the Raspberry Pi. I'm sure there may be others too.
BTW, that is a very cool project. I love the streetlight. Thanks for sharing.
