Codes nomally only require one light next to the service door, anything beyond that is personal preference. Personally, I have a night shift job(by preference), RARELY am I out after dark so I don't bother with exterior lights.
The thing I consider ridiculous is people that think their entire property has to be lit 24-7. I'm often out at 2am, can't believe the people that have all kinds of "accent" lights around their house burning at that time of day. God made it dark at night for reason, and I really despise paying electric bills for things that are of no use to me.
WOW you must live in a very nice neighborhood. Wish I lived there, I wouldn't need the bright lights. My neighbor was so afraid I would shut off my lights on his side he offered to pay part of my electric bill. I just mentioned that if they bothered him, I would turn them off, or put them on a timer. He was afraid I would shut them off and he would have to hire someone to string lights to cover his yard on my side. He's fine on the other side and has three porch lights. His big dogs are in the back yard, so he doesn't need to light it much.
Lights keep the boogie man away...
And by boogie man, I mean the kids, thieves, home invaders, etc. that prey on people who like it dark at night.
The dark houses on our street get hit regular as clock work.
For those in blessed neighborhoods or for inner yard lights consider putting a 12 hour timer on the garage lights. I use one on my shop, turn it to about 30 minutes, it lights up the big florescent, then I can walk back to the house down a lite up sidewalk, no falling, no snakes, etc.
If I go out to the shop at night I turn on the porch light or the big Mercury vapor on the roof.
But working in the shop it gets dark and I would have to find my way back with no light, or leave the light on all night, so rather than string 100 foot of wire and make a complicated setup, I just used the 15 buck timer.
