LEDs not going out

[Otter Spotter]

Hi,
Last night without any obvious reason our LEDs when switched off continued with a slight glow as though there is a tiny bit of juice still feeding into them.
we have the 12v LED strips rebated under overhead lockers x2 and circular ceiling LEDs along the whole length of the habitation area of van switched via the dimmer. All are on the 12v circuit.
don’t see sense in checking fuses, can anyone suggest why they are still slightly lit even though in daylight they appear switched off.
The Dimmer still appears to work correctly dimming and on and off barring the low glow. Any help would be great as my bedmate says they are keeping her awake though I would say it was the 40MPH winds and rain we had overnight.

I made a dimmer for one of our under cabinet LED lights. LEDs light up with so little current it doesn't go off on minimum like an old bulb would. So your problem will probably be something similar. You can maybe try isolating the dimmer circuit with a switch so it's totally off.

Their getting leccy from somewhere so I’m thinking the dimmer isn’t switching off completely and is providing power.

Possibly an induced current from nearby wiring if any runs parallel to the led wiring at any point.
But as said, isolate the dimmer first as that may be the cause.
