Have the neighbor call the fuzz when they show up and have them arrested for tresspassing and vandalism.
Thought about that.You could temporarily put in an outside fixture with a light sensor. But what you have identified there is probably the easiest and least expensive option.
OK, today you need something that just lights up at night, but why use something that you have to install? A lamp or two in appropriate rooms connected by regular extension cords to timers like this two-pack for $17.99 at Target <http://www.target.com/p/timer-2pk-in-thin-ez-set-tmr/-/A-13746917?reco=Rec|pdp|13746917|TargetClickEV|item_page.vertical_1&lnk=Rec|pdp|TargetClickEV|item_page.vertical_1>, each set at different a different time will make the house look occupied.OK timers that would fit inside my current electrical box the cheapest I can find is this one.
A mechanical timer about $18 on ebay.
I really don't need to fancy 7 day programmable ones, but if anyone has any other options - just something that can goes on and off same time every day would suffice, less than $18 if possible.
