[Harry Potter] Flashlights should work at Hogwarts right?

Im not talking fancy flashlights with LED bulbs, I’m talking classic copper wire and light bulb connected to a battery.

It seems to me magic has an almost EMP like effect causing interference with radio waves and anything with more complex than a transistor.

While we could debate EMP hardened devices would work in a magically enriched environment, I would like to posit the idea if flashlights could work at Hogwarts.

Now, a flashlight in its simplest form has existed for over 120 years, with use of a battery, copper wire, a lightbulb, and a container to hold them in together.

We know that Colin Creevey’s camera would work (and in the wiki states that it didn’t need batteries), that it could fire the bulb off thanks to Hogwarts’ magical energies.

We also know that magically enchanted vehicles, such as Sirius’ motorcycle and Mr. Weasley’s Ford Angelica, both had operational headlights, which in large are scaled up flashlights that run off the battery/alternator.

So, what do you think?

Would a flashlight work at Hogwarts?

It's entirely arbitrary. The limits on technology don't seem to be a property of magic but rather the result of a spell placed intentionally to prevent muggles from getting into the wizarding world. Whoever cast the spell would have decided where the line is between acceptable technology and "modern" technology.
