Use colored caps. They are inexpensive and work very well. You simply push the cap over the bulb and it will show the color of the cap.





ChristmasLightShow.com sells many different quantities and colors.





Orange, purple, blue, green gold, are some. There are others, but these are the colors I ordered last year. He also has black out caps (for when you do not want a bulb to shine).Pre-lit Christmas Tree has clear lights, how do I color them without replacing them?
It might take a while but you can get colored SHARPIES and color the light bulbs! It worked perfectly for my tree!
