We have had the same outdoor lights since we moved in over 5 years ago.They are also original to the house which was built in 1994 of 1995 (we're not sure). That means the lights are way too old to still look good. Plus I just didn't like the design and the fact that over 50% of the houses in our development still had them as well.
I picked out a great light two pack at Lowe's for only $31. We purchased 2 packs and got to work.
Problem #1: the hanging bracket pushed the light too far out that it was not flush.
Problem #2: because we have brick the electrical boxes were hung sideways which gave us no room to adjust the adjustable screws to bring the light closer to the brick.
Solution: After fighting with one of the lights by the front door for an hour I called my brother. He can jerry-rig almost anything. So... he used part of the bracket from the old light and put a screw in one way and the two mounting screws in the other way. We used nuts to hold the screw in the right place and rigid so the light had something to hold on to.
