I sure hope this LED Christmas tree passed its EMI tests.

Does it plug in to the cigarette lighter socket?

I'm pretty sure that the white cable leads to a "UL listed" wall wart.

I'm always a bit nervous around those 240v Christmas lights that plug directly into a mains socket. No plug packs, no fuses, nothing, just wire and light bulbs.

Cool, link sent to pilot daughter. :)

I don't see the problem: I'm sure Santa has TCAS.

It's a plug and play ILS :-+ :) :-- , she who crashes the car when parking could do with one of those on the dashboard. ::) :-BROKE

Could just be powered off a USB powerbank or AA batteries.

Almost caused a fire once with one of those shitty mains LED light strings. It had a small box that controlled the blinking patterns. The mains wire had no strain relief at all, at some point it broke and shorted out, but not enough to actually trip the fuse or RCD. It went full PhotonicInduction. Good thing I was actually there, otherwise it would have set the house on fire.
No more cheap garbage mains stuff for me since then.

Do you also feel nervous about your toaster? It's even worse as it has exposed mains-connected heating filament:) Only anti-electrocution solution is this grounded mesh that can be defeated by a badly positioned kitchen fork or simply connecting the appliance to unearthed socket.
People from electronics era are for some reason scared about any device that connects to mains directly despite it was the most common way to do anything since the beginning of electricity.

I'm sure disasters involving light strings aren't very common, but correct practice is not to leave them plugged in unattended. Cut Christmas trees are capable of amazing pyrotechnics.

I am amazed with the stuff I was allowed to do as a child. Shortening the length of fairy lights and plugging them into the mains.... Aged 6 or 7.... Flame throwers out of quater inch copper pipe, cotton wool and methylated spirits... Gathering the dud caps from nail guns off the ground on building sites....
I got my one and only real electric shock off those lights. One way of been taught to respect electricity at a young age.
