LED Strip Lights – Troubleshooting

Spread the love

LED strip lights are easy-to-go lights for right-angle corners and straight lines. Their easier plug-in installation makes them simpler for the decorators to use than their sibling rope light. Yet LED strip lights have some quirks and common problems. Below given table shows the most common causes of LED strip light failures. With depth explanations of the failures and the solution to solve them, things will be easier for you. 

IssuePossible CauseSolutions
Sudden Light Came on–And stopped working,

They are not lighting up.


Won’t Chase or Flash.

At the end of the strip, the light is different.

RGB Light stays at one color,

hot to touch.
You may be using the non-compatible dimmer, or the connection is lost.

Loose connection; the battery is dead or dying.Or the light may not be plugged in correctly and isn’t switched on.

Voltage of power supply is low; Battery of RGB controller is dying
If lights are connected with dimmer;Dimmers stop strip light from chasing or flashing. 
Voltage Drop

Backward Connection

Voltage is high. 
Check the dimmer’s connection and spec chart for compatibility.

Replace batteries or Check connections.

Check the lights and driver match voltage;Replace old batteries, 

Disconnect them from the circuits,

Use multiple LED drivers to divide your strip light run. Per driver max 16 feet 
Flip around and reconnect your strip light

Check the voltage of driver match and lights

Bad Pin Connection – If your LED strip lights are unable to turn on, check the pin connections to make sure that they are connected. Most probably, your pin is not connected correctly. In very rare cases, the pin is defective. You have to be very careful while inserting connectors, as these are a little and delicate item. These can be easily damaged or broken if you press them hard. 

Bad Pin Connection

A reversed polarity or backward connection also comes in a bad pin connection. Typically, one side of the light has the positive charge, and the other side carries the negative charge, generally noted by a negative sign. Due to reversed polarity, color changing or RGB LED strip lights mainly stop working. 


Wrong Power Source – Always double-check to ensure the power source your lighting system requires. LED strip lights come in 12 or 24v versions. For short runs such as motorcycles or automotive vehicles, a 12v strip light is used, so most people don’t install LED drivers. 24v strip lights run longer, mainly used for staircase and under cabinets lighting. Using a 12v driver for 24v strip lights causes flickering, dimming, or light damage. Overpowering your light is also not suitable as it will make your light hot, leading to light failure and wiring fry. The transformer’s output voltage and the driver must match with the needed input voltage by your LED strip light. 

Additional Problem-Solving Tips

Why won’t my led lights turn on?

There are various reasons why your light is not working properly or turning on. You may be using the wrong power source or driver. Loose connections and the battery dying is also one of the reasons. Check all the aspects to find the right solutions. 

Can I cut the waterproof LED strip lights? 

Definitely, you can cut LED strip lights, but cutting them will null the IP and UL ratings. After cutting, you can’t reseal the end enough to stop water from entering in the connection. Check the product details and specs before cutting them.

Problems can occur with any lighting system. You just need to troubleshoot to find the problem and the solutions. There aren’t any problems in some cases, just a mistake of not switching on the light or using the dying battery. We hope you have got the solutions to your problems in this blog.
