Ceiling Light Problem

[far2many]

Good afternoon,

I was hoping you might be able to help.

After being let down by several electricians saying they were coming then not turning up my brother arranged for his mate an electrician to come and put up two LED ceiling lights for me. They are:

Dar LUT0675 Luther 6 Light Crystal Semi Flush Ceiling Light, Antique Brass​

I have attached an image of the light and of the wiring that was in the rose before being hung.

There is a switch on the wall with three rocker switches on it. One to turn the upstairs light on/off. One to turn the downstairs light on/off. One to turn the outside front door light on/off (its literally on the other side of the switch on the outside wall).

The upstairs light works.
The downstairs light turns off and on. However, when it is dark you can see that the LED's are lit up a bit. Should electricity be getting through when it is turned off? Why is it only lit a little bit? Is it a danger to the house?
The outside light did work at first. Now it doesn't. The bulb was taken out and brought in and placed in a lamp where it does work.

Any thoughts of what this is and if its a danger? I will obviously get a different electrician in but they are all booked out well in advance. One of the other ones i texted him this and he has blanked me. I'm trying to work out if my house is imminently in danger.

Any help or advice would be greatly appreciated.
Thanks

Don't worry. LEDs glowing when switched off is a well known phenomena. It happens because they can glow with very low current indeed, and that can be capacitively induced in the wiring. It's especially common on two way circuits because of the extra wiring used. Absolutely no danger but if it annoys you ask your spark to fit a device called a snubber which will stop it.
No idea about your outside light, but with wiring having been disturbed a loose connection is possible.
