Agreed, this is an issue with motorcycles, too. Minimum legal separation here in Washington is sixteen inches on motorcycles, and even that isn't enough for all drivers to reliably identify the direction being signaled.

Personally, I think I'd find the flashing down at the ground annoying on a dark commute. But it might not be hard to fit in a tilt switch.
Quite apart from whether they work, you might also look into what their legal status would be in your jurisdiction. Two separate questions, really -- are they allowed on a bike, and are they recognized as turn signals?
Are they allowed? They're a flashing light that isn't a tail light, what flashing lights does your state allow for bicycles?
Are they recognized? If your state only defines hand signals for bicycles, turn signals may not legally qualify as having signaled your turn. Not likely to get a ticket for not signaling if your signals were visible, but could play into liability after an accident. "Ladies and gentlemen of the jury, poor old Mrs. Jones would never have struck the cyclist, if only he'd signaled legally..." Plays right into the scofflaw cyclist stereotype.
Look again at my signals...

especially during nighttime hours, you can DEFINITELY tell which direction I'm heading.
Theyre really good during the day too!
I've been using them for 6 months now and not once did I have a problem.
Who said anything about not seeing it?

It's the same sort of issue as not having legally-mandated reflectors, even if you have more than adequate lights.
Lawyer: "Did you have a red rear reflector visible at 600 feet, and reflectors on both pedals?"
Mr. Jones: "No, I had...." Lawyer, interrupting: "Thank you, Mr. Jones. Your honor, please direct the jury that Mr. Jones has admitted not having the reflectors required by law."
Do your signals comply with the law in the jurisdiction where you're using them?
