Blue outdoor Christmas lights have caused "havoc" for police helicopter crews trying to spot emergencies from the air, it has been claimed.
The National Police Air Service (NPAS) has 25 aircraft to support police forces across the country.
Its Boreham base in Essex said it had noticed an upsurge in the number of homes with blue Christmas lights.
They claim the outdoor decorations have made searching for a "set of blues" at night difficult.
The issue came to light, after a message was posted on the social media site Twitter by the NPAS's Boreham team.
It said: "Blue lights are the must have outdoor accessory for 2012. Plays havoc when you're looking for a set of blues."
