“It’s quite hard at this point in time, we are managing that, but there are still back doors that are open (for the banned lights marking it to store shelves).

PPL safety and awareness information on its website encourages shoppers to “always perform a basic safety visual check on Christmas lights before buying them.
“There has been an influx of illegal decorative lights into the country so always check the insulation thickness or plug configurations before purchasing the lights or any other product.”
