The most important thing you need to establish is what type of lights you need, typically displays use C7 or C9 bulbs, Mini lights, Rope Light, or LED Christmas lights.
C7 and C9 type bulbs are the easiest to fix or revamp. These glass bulbs need to be replaced every few seasons, mixing and matching old and new bulbs isn't what we recommend because the colors/brightness of the bulbs won't be consistent. Hours of burning the lamps, plus being exposed to UV will change colors and the brightness does tend to fade after a seasons worth of hours. So before you decorate with your piece, plug it up and establish what needs to be replaced, if you need many lights we sell incandescent bulbs in bulk for this type of job!
