How do color changing Christmas lights work?
Colour-changing light bulbs use red, green and blue LEDs to create their range of colours, switching them on in different combinations using a tiny computer (‘microcontroller’). If you want yellow, the bulb turns on red and green. For cyan, it turns on green and blue. For white, it turns them all on.
Why does only half a string of LED lights work?
If half a strand is working and the other half is not, you probably have a loose or broken bulb. If not, you have the more tedious job of going down the row of unlit bulbs, one at a time, and swapping them for a known, good bulb until you find the culprit. You’ll know it when the strand lights back up.
Do LEDs change Colour?
Strictly speaking, an individual LED can’t change color. Instead, a color-changing LED is made up of three separate LEDs in one casing, with a micro-controller operating them. The three LEDs are red, green and blue, so any of these colors can appear at a specific time simply by passing a current through one LED.
How do you work with LED strip lights?
LED strip lights are designed to be easy to cut apart with a pair of scissors. Each LED has a pair of copper dots at the end. As long as you cut between the dots, all of the LEDs will work. From there, you can connect the LEDs to a power source either through a quick connector or by soldering.

How do led Christmas lights work?
LED Christmas lights use light-emitting diodes, rather than filament to produce light. This new technology makes LED lights more efficient, durable, and longer-lasting than fluorescent incandescent lights. They don’t burn out, like other bulbs; and they also don’t get hot to the touch, so they’re a lot safer, too.
How does tape lighting work?
Reflective tape (also known as retro-reflective tape) works by reflecting light back to the light source only. In other words, the tape only lights up for the person with the light source or in line with it. For example, lets say two people were walking down a street with one person on each side of the street.
