If safety is your number one concern, you would retain the stock orange pumpkin signals. They are the most visible signal I've seen around.
I own a kawasaki. Kawasaki oem signals are hard to see. I have expensive (100 bucks a piece) italian LED signals on another bike which are eye-blinding inside the garage. They are hard to see in sunlight. I have ridden behind all my bikes operated by other users. The only signal I can see every. single. time. during daytime/sunlight through my peripheral vision (ie., I'm not staring at the signals) is the stock yamaha signals.
Flush mounts are probably the worst, hardest to see signals around. Do yourself a favor. In sunlight, turn on your bike, turn on your signals, walk 100 feet away and see how well you can see the signals. Yeah, and now imagine you are in a car and not staring directly at a bike's signals. Might as well buy 50 dollar pieces of jolly ranchers candy and super glue them in place where the signals are. They might almost be as effective as flush mounts.
If safety is priority, you will retain the stock signals. That said, no one really cares about signal safety in their tier of priorities. Most if not all sportbike owners care more about looks than safety. Do whatever you want.
If you argue with an internet moron, everyone loses.
