Yes, you can try removing and replacing each individual light bulb one at a time until you find the problem bulb—just be prepared for it to take a while. The bulb tester is worth the investment if you don’t have a lot of extra time to spare or need to test several strands of lights.

Ensure you have a safe environment for them to work on, and there aren’t items such as logs, build-up of yard materials, missing or damaged shingles, and weak areas on the roof. Communicate any known electrical issues with contractors at the beginning of the project, and consider hiring an electrician to fix those. Finally, if you are attempting the project yourself, do so when there isn’t any rain, and you can safely get your footing on the roof using proper equipment, such as an extension ladder. Don’t attempt this alone, and have a helper nearby to assist.

Repairing a strand of Christmas lights will save you a few dollars and the hassle of going to the store to purchase new ones. That may or may not be enough to make fixing them worth it to you. However, if the lights are already hanging or around the tree, removing and replacing them is far more time-consuming than performing a quick repair job. 

The cost for professional holiday light installation averages around $430, with a typical range of $220 to $675. However, prices can be as low as $100 for simple projector setups or exceed $1,200 for extensive displays. The total cost depends on factors like the display's complexity, your home's size, labor rates in your area, and the type of lights used. For example, installation on a small, one-story home may cost $250 to $600, while a multi-story home over 4,000 square feet could cost $500 to $1,800. Costs can also be broken down by location (e.g., high roofs at $3.50–$6 per linear foot) or by the type of light strand, with prices ranging from $4 for basic incandescent strands to over $60 for color-changing LED strands.
