If you're talking about legality and if it's in France then the answer is "no". But then if you're talking legality in France it's one red rear light, no flashing or strobe, and a reflector back and front. Orange reflectors are used everywhere on a bike that is not a direction covered by a red or white reflector. As you will undoubtedly know, no-one sticks to the rules at all (and electric trottinettes in the middle of the road two-up without lights are far more of a danger, both for the riders and the other road-users).
However you need to be very careful about strobes that are not red or white. A blue strobe is not, and should not, be tolerated since it can be confused with emergency services and utility workers. Orange strobes are for highway maintenance, heavy haulage (including in my part of the world, and some others, timber trucks going up to 55T, and a whole host of off-road vehicles from giant tractor-trailer combinations to lawnmowers. You could get into trouble with an orange strobe on a bike but it would mostly be a telling off.
I can't think of anything that uses a green strobe so I don't know what the response would be, probably not much (unless it's something military or nuclear waste
)
