Main information
What it could mean
An LED that stays slightly lit or flickers faintly after switching off usually comes from a small residual current, common with illuminated switches or certain dimmers.
Safety first
Not an electrical risk; it's a known effect from the interaction between some LEDs and certain switch types.
Next step
Assessed whether the current switch is compatible with LED bulbs or whether a more suitable model is worth switching to.
Frequently asked questions
Is it dangerous for the bulb to stay slightly lit after switching off?
Not usually; it's a known effect from very low residual currents, though it can be annoying.
Why does it happen more with illuminated switches?
Those switches let a small current through to power their own indicator light, which can affect sensitive LED bulbs.
Is it fixed by changing the switch?
Often yes, by replacing it with a model without an indicator light or one compatible with LEDs.
