An LED mirror that flickers may have a power, driver, control or LED fault. If it only flickers on a phone video, first check whether the light looks steady to your eyes. The pattern matters: a whole border flashing, one dark section and a light that pulses only at a low brightness setting can point to different issues.
Before replacing a mirror you otherwise love, collect a few useful details. You can check the normal controls and describe the symptom without taking the mirror off the wall or opening its electrical housing.
Start with what you can see
- Watch the mirror directly, then through your phone camera. Camera banding alone does not establish a fault in the mirror.
- Notice whether the whole light flickers or just one section. Check whether the display, demister indicator or other functions also lose power.
- Use the normal brightness control to see whether the symptom happens at every setting or only when dimmed.
- Note when it began: straight after installation, after a change to a wall switch, or after months of normal use.
If the light is steady but weaker than you expect, follow our guide to a dim LED mirror. Dimness and flickering are different problems, and buying a brighter mirror will not resolve an unsuitable supply or switch.
A wall dimmer can change the diagnosis
A mirror with built-in touch dimming is not automatically compatible with a dimmer on the wall. If flickering began after a switch change, tell the installer the exact mirror and control arrangement. Let them check compatibility rather than fitting another dimmer or voltage regulator by guesswork.
For a new installation, take a short video and contact the installer or seller before altering anything. For an older mirror, a compatible driver, control component or LED section may be repairable. Our guide to replacing LED mirror lights explains what a repair involves.
When to stop using the mirror
Switch off the supply if you notice a burning smell, unusual heat, crackling or repeated circuit tripping. Arrange professional help. Electrical Safety First recommends a registered electrician for bathroom electrical installation work. Do not open the housing, tighten internal wiring, spray the electronics or attempt to reseal a powered mirror yourself.
For flickering without those warning signs, contact our support team with your order details, the video and the settings you tried. That gives the team a much clearer starting point than “the light is not working”. See also common LED mirror problems and why a mirror keeps flashing.
If you are upgrading, choose the light you want to use
Replacement is worth considering when repair is impractical or the mirror no longer suits the room. Choose by size and light direction, rather than expecting a new design to fix a fault in the electrical installation.
60 × 80 cm dual-light mirror — £129. Front lighting illuminates towards the reflection, while the rear glow adds atmosphere. Dimming, three light colours and anti-fog make this a flexible choice for a busy vanity. Browse more rectangular LED mirrors for a similar clean outline.
50 × 70 cm oval dual-light mirror — £148. The curved shape softens a tiled wall without giving up practical lighting. Compare oval bathroom mirrors if a gentler silhouette is part of your refresh.

Flickering questions, answered
Does flickering mean the LEDs have worn out?
Not necessarily. The supply, driver and controls can also cause flickering. Identifying the failed component is more useful than ordering an LED strip first.
Should I keep turning it off and on?
A normal switch-off and restart may help you describe the behaviour, but repeated resets are not a repair. If the fault returns, record it and seek support.
