See that black bit of fabric on the back of your seat bag that's 2 or 3 inches long? That's actually there specifically to attach your blinky light to.
I put a light on my seat bag because being up higher, it's less likely to be obscured by someone's hood or another car.
The issue with putting the blinky on the bag is with it popping off over bumps. I drilled holes in the plastic clip part, threaded a twist tie through the holes and tie it off. Never ever lost a light since I did that, though it's a little work.
If that somehow isn't an option, I would agree that if people drive on the right, putting the blinky on the left side would be better than on the right side - you wouldn't want someone to miss seeing your bike because they happen to look over when your wheel happened to be between them and the blinky light.
