Troubleshooting Common Issues of LED Strip Lights: From Flickering to Dead Sections| HItLights

Table of Contents


LED strip lights are a popular and versatile lighting solution, but they can sometimes present frustrating issues, such as flickering or dead sections. This blog post will guide you through diagnosing and fixing the most common problems with LED strip lights. These insights will help you maintain the perfect lighting setup.

Understanding LED Strip Lights

What are LED Strip Lights?
LED strip lights consist of a series of LEDs mounted on a flexible circuit board. They come in various colors, intensities, and lengths, and are used for accent lighting, task lighting, and even general lighting in homes and businesses.

Key Components
  • LEDs: Light Emitting Diodes, the primary source of light.
  • Flexible Circuit Board: Supports the LEDs and provides connections between them.
  • Resistors: Regulate current to prevent overheating.
  • Controller/Dimmer: Used for changing colors and adjusting brightness.

Common Issues and Solutions


  • Compatibility issues
  • Inadequate power supply
  • Loose connections
  • Overloaded circuit

  • 12V low voltage lighting works with 12V power supply/driver
  • Check if the driver is dimmable
  • Check if the driver has enough power to supply the lights e.g. 30 watts load but driver is only 25 watts capacity
  • Secure all connections and ensure there are no loose wires or connectors
  • If you have an extra driver - swap the driver and test if this resolves the issue, check the warranty of the driver and contact the manufacturer

Dead Sections

  • Cut or damaged strips
  • Poor soldering or connections
  • Worn out sections (wear and tear)
  • Product defect (poor quality)

  • Inspect the strip for physical damage and replace it if necessary
  • Check for loose or burnt connectors - reseat or replace connectors to ensure solid connections
  • Check how long you have had the LED lights installation? Ideally, low quality LED lights lasts for about 10,000-25,000 operating hours (roughly 1-3 years), high quality LED lights lasts for about 50,000 operating hours (5-10 years and up)
  • Check if the dead section is in between working LED lights - if it is, contact the manufacturer for a possible warranty replacement

Color Inconsistencies

  • Incorrect polarity LED strip alignment (common in RGB and RGBW multi-colored strips)
  • Inconsistent manufacturing quality (poor quality LED strip lights)

  • Check and re-align the colors of the connections i.e. red to red, green to green etc
  • Check remote programming and reprogram the LED strips
  • Purchase high-quality LED strips from reputable manufacturers

Dimming Issues

  • Incompatible dimmer switch
  • Insufficient power supply or voltage drops over long runs

  • Ensure the dimmer is compatible with LED lights
  • Check the power supply and upgrade it to match the demand of your LED strip setup
  • Check maximum run of LED strip lights. Go for parallel connections to distribute the load and not get impacted with dimming on longer runs

Preventive Maintenance Tips

  • Regularly check your LED strip setups for any signs of wear or damage.
  • Ensure that all connections are tight and covered to prevent exposure to dust and moisture.
  • Use a multimeter to check for voltage consistency along the strip, especially for longer setups.

When to Seek Professional Help

If you've tried all the above solutions and still face issues, it may be time to call in a professional. Complex installations or persistent problems could indicate underlying issues that require expert attention.


While LED strip lights are generally reliable, they can sometimes present challenges. By understanding the common issues and how to troubleshoot them, you can ensure your LED lighting remains bright and functional for years to come. Remember, regular maintenance and using quality components go a long way in preventing most problems. For more persistent or complex issues, don't hesitate to seek professional help to preserve the integrity and beauty of your lighting setup.
