Hiya supcarlos,
You can't go past Firehouse Technology (FHT) strobes for size, weight, output, got to be best for smallest, lightest, brightest for performance.
The ARCII are the pinicle of the bunch, but you can actually blind yourself if you look at them !!

That said, there are a few others people use, a search here does bring up many recent threads where you could easily glean all the info you want for peoples input.

You can set your
M2P up for night flying in different ways.
Technically you should make it visible to others, and yourself, by placing lights as planes do for night orientation.
A red to left front, a green to right front, and one or two whites to the back.
If you only wanted to find your drone easily at night, you could just mount one bright white to the rear, and simply turn your aircraft slowly to see strobing, or, in combination with your map, just align your red arrow so it's facing away from you, then use the map to get final direction.
You should be roughly facing your bird anyway, to keep goo signal, so the map is good to use there anyway.
I'd say of the FHT strobes are in order of brightness ARCII, Dual, or perhaps the little "Spark" strobe they make.
I have all of these (bought recently) but yet to get up in the air to test them.

You can get ARCII and Duals in sets / various colour combos, the ARCII are available in the RED/BLUE and WHITE/RED colours, very bright too, but without a doubt, colours in order of brightness (highest - lesser) white, red, green, blue.
While you can fly at night as a hobbyist, without restrictions (as yet), even part 107 pilots can't without a special waiver.
FAA overlooked this, but pretty sure they will fix it very soon, and night flying will only be available to part 107 with waivers.
