The source of the metal 12 Volts LED Indicator Lights?


In July 2016, a customer from Los Angeles, USA contact us by e-mail. The customer said he is a trader and accidentally saw our website on Google. He found that the content of our website is very professional.

Through our communication, the customer has been purchasing metal 12 Volts LED Indicator Lights in China before. However, the product often has quality problems. Either the LED is not bright or the wire is broken. What’s more, the appearance is ugly, which leads to his business being miserable.

He sent the product photo they purchased before to us. The product price is relatively low, but his Chinese supplier was not professional. Because our current high-end 12 Volts LED Indicator Lights are too high that he couldn’t accept them, we decided to customize an indicator light with a superior price and better quality and appearance for the customer.

Where are the lights used

How to connect the wire with the 12V LED indicator light?

  • Firstly, you need to ensure that the equipment is not powered on, then start to the next step.
  • Find the wire to be connected on the device and distinguish the neutral wire. Red is the live wire, blue is the neutral wire. If you are not sure, you can test with an electric pen. One end of the light is the live line and the other is the zero line. Remember, never touch it with your hands.
  • The next step is to cut the thread. After finding the wire, use small pliers or small scissors to pinch off the skin of the corresponding wire end on the equipment to expose the longer copper wire. Remember that the leakage of copper wire is not too short, or the connection is not easy to connect.
  • Ready to wired. Firstly, fix the indicator light in the right place of the equipment. Connect the positive and negative wires of the 12V LED indicator light to the two wires corresponding to the color of the power supply. Don’t forget to pinch the string of the lamp holder.
  • The last step is to use tape to fix the wiring mouth. Remember to buy an electrician special insulating tape. Wrap the wire with tape and fix it and tighten the tape.
  • Restore the wire to the original place. Power on the equipment and try to open the equipment to see if the indicator light works normally. If it is on, it means the connection is successful, otherwise, there is a mistake in one of the above links.
