It's the final round of our big bright holiday showdown, "My Lights Are Better Than Your Lights." Families from across the country with amazingly outrageous holiday lights displays have faced-off every day this week.

Meet the three finalists:

The Schmidts of Georgetown, Texas won Monday's showdown with their display synchronized to remixes of the family's favorite Christmas songs.

"This is a family event. From our son to my wife and myself, [even] my 13-year-old has been helping put this together since he was old enough to talk and walk," they told us.

The Ziemkowskis  of Sherman Oaks, Calif., took Tuesday's face-off. Their wild lights show is also a family tradition, now in its twelfth year. The computer-controlled show has synchronized LED lighting, animatronics and video set to a medley of Christmas songs and infused with other handmade touches.

The Whitis Family  of Tallahassee, Fla., won Wednesday.  Their display is a tribute to U.S. troops and veterans and uses over 170,000 LED lights, synched to "God Bless the USA."

So who do you think has the best lights? It's up to you to pick the big winner.
