Yep, 502,165 is the number of LED lights you'd have to beat to hold the 2013 Guinness World Record for most Christmas lights in one display.

David and Janean Richards from Canberra, Australia have earned the title for the second time. They initially set a record back in 2011 with 331,038 lights, but were overtaken by the Gay family from Lagrangeville, New York.

So in October, the Richards worked hard at installing a much bigger and brighter spectacle to claim the title once again.

Guinness says the display includes more than 31 miles of lights, "520 Lightorama channels controlling a [164-foot], walk through, multi-coloured canopy and an [60-foot] light-controlled tree (all animated and synchronised to music)."

It's not cheap either. Richard says his electric bill runs about $2,291 each month the lights are up, although a local energy company is covering the cost. Ultimately, the Richards' goal with the display is an altruistic one; they're raising money for a charity called SIDS and Kids ACT, which works to reduce Sudden Infant Death Syndrome.
