When we purchased the Road House, the seller asked if we would like her to leave an artificial Christmas tree behind. I assumed it was too large for her new Boston apartment. When I assembled it today, I discovered the real reason. About a quarter of the pre-hung lighting strings were not working. Other than this, the tree is very nice so I decided to fix the lights. After replacing 98 burned-out bulbs and only restoring function to half the lights, I decided to call it quits after two hours with only two replacement bulbs left. Making the job most tedious was the fact that I had to swap the base on each bulb since the replacements were not a good match to the originals.
