The competition offers $500 worth of local prizes in each town, with special consideration given to displays that capture community spirit.
Lockmore Financial Services executive officer Lauren Ross said the initiative is a fun and meaningful way to bring the community together after a busy year.
“This competition is all about celebrating the people who make our towns such wonderful places to live,” Ms Ross said.
“It's great to see our streets lit up and families out enjoying the displays together - it really captures the spirit of what community is all about.”
The competition also supports local businesses during the crucial Christmas period.
“With all prizes purchased locally, it's also a fantastic way to inject cash back into our communities at Christmas time,” Ms Ross said.
“It’s great to be celebrating local creativity while supporting our local traders.”
Entry is free, and locals can register their displays by completing a form at Community Bank Elmore, Lockington and Rochester, Lockington Neighbourhood House or Rochester Community House.
Prizes include Elmore IGA vouchers, Locky Dollars and Rochester Business Network gift cards.
Please ensure to include a photo of your light display with your entry.
Entries close Friday, December 12, with judging occurring mid-December and winners announced before Christmas.
