I've had terrible luck with the prelit trees, but that seems to be all that is available up here.
Last year, I got a good pair of scissors, cut out all the lights, working or not, and just strung it with new store bought lights. I also took the opportunity to swap out from mini clear lights to slightly larger, green and pink lights.
It took a little getting used to, but basically I was happy.
Hubby loved it. Didn't really want me to take it down.
Overall, the theme of my tree is Victorian, in purple, rose and cream (I weeded out the dusty rose years ago), so it worked.
