PICKERING, Ont. -- A couple of years ago, a light bulb went on for Colin Bates.
Now, there are tens of thousands of them.
Bates is behind Rigby Lights -- possibly the coolest Christmas light display in the country, if not the geekiest.
Four consecutive Pickering houses on Rigby Dr. are linked together for a light show synchronized to holiday music. Itís the only light show of its kind in Canada.
