Local residents are being asked to leave a light on when they go out – so that it looks like someone is still at home.
As the days get shorter and evenings arrive earlier, it is easier for criminals to work out if a property is empty if it is in complete darkness.
Neighbourhood police teams in Lancaster and Morecambe will be looking out for homes without lights on while they are out on patrol and will then pop a card through the letterbox asking residents to leave a light on next time they go out.
The action comes after 750 free timer switches were given out to people in Carnforth, Lancaster, Morecambe and Silverdale last week in a bid to improve home security.
The crime prevention devices turn lights on at set times so it appears someone is in, even when they are not.
Crime prevention officer Jan Brown, Lancashire Police, said: “Although crime is low in Lancashire, a house in darkness can provide temptation for a passing criminal, as they believe they will go undisturbed.
“Residents can help us keep crime low by leaving a light on while they are out, drawing their curtains and making sure their doors and windows are locked and secure.”
Jan added: “There are a number of other measures people can take too, especially if they are preparing for the winter. Check walls, hedges and fences are in good order; fit good quality padlocks on gates, sheds and garages and make sure all tools are locked away when they are finished with.”
