PUT that light on! That's the simple crime prevention message this autumn.
And you can put the radio on, too.
And, come to think of it, the TV - along with anything else that could put a burglar off.
People are urged to buy easy-to-use timer switches to give their homes that lived-in feel even when they're out.
Russ says: "During the summer's light evenings our main problem with burglaries are sneak-in thefts after doors and windows are left open or unlocked.
"These type of easily preventable crimes still happen in colder weather - but the problem now is that people also advertise to burglars they aren't at home.
"Once darkness falls no burglar can miss a house that's in total darkness with the curtains open.
"That darkness is a beacon of light to them.
"But thieves don't like lights.
"Simply use timer switches, so lights and other electrical equipment comes on automatically.
"It makes coming home more welcoming and certainly helps to keep burglars at bay.
"If they feel there is a chance of someone being at home they'll simply move on to a darker - and easier - target."
Russ also urged people to put security lights around their homes.
"There is a cost, but they are a vital crime prevention measure and a sound investment," he says.
"Security lights not only protect your home, but also your other most valuable asset - your car on the driveway.
"If there is one thing criminals don't like it's bright lights with sensors that can catch them in their full glare."
A couple of students at the Snow Island student accommodation near Huddersfield town centre fell prey to thieves who did not even have to get in.
One leaned through a ground-floor window and stole a laptop computer, a digital camera and an X Box games console.
Another had her handbag stolen by a thief who lifted the window and grabbed it.
Russ says: "If the windows had been locked these crimes would not have happened."
