How to Check Christmas Lights With a Non-Contact Voltage Detector
- Plug the lights into an outlet.
- Turn on the non-contact voltage detector.
- Replace the bad bulb, and then try the lights.
- Discard the string of lights if they are not working because of faulty wiring.
Can you use voltage tester on Christmas lights?
Bulb Tester is non-contact AC voltage detection, used as a 12V to 600V AC power tester, allows you to easily find any burned out bulbs on your Christmas lights. Christmas Light Voltage Tester can test wires, fuses and bulbs.
How do you test Christmas lights with a tester?
Press down the black button, hold the tip about 1/2 in. from the string, and move it along the cord until it stops beeping (at the defective bulb). There’s a way to test (and fix) the entire string of miniature lights without testing each bulb individually. Try the LightKeeper Pro (www.lightkeeperpro.com).
How do I know what voltage my Christmas lights are?
If the filament glows bright white, then you have a 2.5 volt bulb. If orange the bulb is 3.5 volt. If dull red, continue to 6 volts. Continue to the next higher voltage until you see the bulb’s light output is a yellow – white shade.
How does a non-contact electrical tester work?
Non-contact voltage testers work by sensing a very small amount of current that is capacitively coupled from the live circuit to the tester and back to ground. A built-in sensor at the tip of the tester detects the presence of voltage when touching a conductor, outlet, or supply cord.
Why don’t my Christmas tree lights work?
This often occurs through rough handling or improper storage of a tree. Look to find the loose bulb, check the wires to ensure they are properly aligned, and secure the bulb tightly within the socket. This should fix the issue. If a short has occurred, the light string is usually not repairable.
How do you tell if a Christmas light is burned out?
You can tell which bulb is out on your string of traditional Christmas lights by looking for the bulb that is “burned out” by looking at the tiny little filaments in the light bulbs to see which bulb is “burned out” or has lost it’s filament. Many times the bulb will be “smoked” as well.
