I have one of these modules:
Is it safe to connect it to two pins to my Raspberry Pi, directly, and turn it on by emitting HIGH on one of the pins (the other one being the ground), which is around 5V, if I am not wrong?
Will that use too much power from the Raspberry Pi or maybe burn it?

There's nothing to be gained in casting aspersions on the OP's motives. Whatever these modules are, they're apparently cheap and plentiful on ebay, so plenty of people will likely be playing with them for all sorts of reasons. Best if they know how to do that without killing their Raspberry Pi's. :)

The advert says it needs 5 Amperes. That’s hundreds of times more than a Raspberry Pi GPIO can supply.
You would need a driver, preferably with isolation, and a separate power supply capable of at least 5A. One solution would be a CPC709J, with a suitable series resistor for the LED.
You may well cause disruption or damage even with that, but the chances are better. You’re essentially putting a multi-watt spark-gap transmitter in close proximity to an unshielded microcomputer.

Absolutely, but you also then need to build a relay driver, and relays don’t give perfect isolation either.

The micro-lightning arc HV noise generator needs 1 or Li-Ion cells to power it. If should never be operated near any computer.
If it operates near an R-Pi, it will cause functional failure and possible damage to signal ports on cables acting as an antenna.
