I have a motion activated light by my back garage door. I installed lights on top of my patio cover that I can turn on if someone is on the hillside above my home. I have landscape lights in front, back and both sides. I use the spot lights to highlight recessed corners and the fence. I made it look like the spotlights on the fence are highlighting some decorative items I hung on it, but it is really so that burglars know they cannot get over the fence without being seen. I also keep the trees and bushes pruned under the height of the windows so that they do not provide an obscurity that criminals could use to enter. A very bright motion detecting light above the garage door not only gives visitors light to get up to the front entry, but discourages criminals from messing with cars in the drive. Finally, I replaced the fixtures the builder provided at the front entry because they could not accomodate a bright enough bulb to illuminate the entire front walk and porch.
Inside my home, I have lights on timers in several rooms so that it always looks like someone is home somewhere in the house. I set them to go off at different times so it also looks like there is more than one person home, but randomly enough that there is no regular schedule. I also make certain that neither mine, nor my neighbors, newspapers, ad circulars or any other stuff, accumulates so that no one knows when any of us are out of town. We rarely leave our garage doors open, even when we are mowing the lawn. We've had a lot of petty theft of tools, CDs out of cars, stored items in garages, in broad daylight. I think theives scope out the garages, pick out what they are after, get in and out in a flash.
