Incorrect access to statis members

[riverajo]

It appears that the LIGHT_ON and LIGHT_OFF have been changed to static memebers. This is the correct place for them, however they are still being accessed as instance memebers i.e. self.LIGHT_ON in the Relay class. While this will work it may confuse a reader, they should be accessed like Relay.LIGHT_ON and Relay.LIGHT_OFF

that's my inexperience with creating constants....
