Backyard Lighting, Part II

We installed a craftsman-style light just outside the kitchen door to the back deck:

Using an extension cord, we plugged a long string of lights into the new outlet under the deck.  Initially, we had this string of lights on the railing of our deck.  But, we recently moved it to run up the plum tree in our backyard (which grows up through our deck):

Tough to get a decent picture of them at night:

As you can see below, the lights are made out of a lightweight metal with star patterns punched out.  I like to think of them as quasi-craftsman style.  

We're considering getting a string of white lights to run all the way along the deck railing (the quasi-craftsman metal lights only ran part-way along the deck railing).  Maybe holiday-style white lights -- just something to brighten things up a bit.
