Why Does My LED Illuminated Bathroom Mirror Keep Flickering?
Light flickering is a common problem with illuminated bathroom mirrors. Nothing ruins a relaxing time faster than a flashing mirror in the bathroom.
LED mirror flickering is usually caused by broken connections, dimmers that don’t work with LEDs, voltage fluctuations, or LEDs that are getting old. Most of the time, flickering is caused by moisture getting into the electrical links and messing them up.
At first, check the wires connections. I solved the issue by making the connections tighter on the power supply or inside the mirror case. Over time, Constant bathroom humidity can corrode wiring connections, which causes LED mirror lights to flicker.
If the links between the wires are good, look for changes in the voltage. Changes in voltage can damage to sensitive LED components. I noticed that my mirror seemed to have more problems when it rained or when high-power appliances were on. This problem was resolved by adding a voltage stabilizer.
You can also look for problems with the LED parts. Over time, LED drivers break down. Especially in damp places. This means that the LED components need to be replaced.
