General: LED Bike turn signal lights- Quick survey

Hello,
I am an industrial design student and bike commuter, and I need some research information. Would you please take the time to answer a few questions I have about bike turn signals?
1. How do you indicate turning? Proper arm motions? Point your arm in direction going?
2. Do you have any LED turn signal devices? If so, do they work well? What could be improved with them?
3. If you don't have LED turn signal lights, would you consider getting some?
4. What would you like to see in a turn signal device? Seat post mount? Backpack lights? Arrows?
Anything else?

Thanks,
nttilma

Thanks for your feedback.

Hello nttilma, I'll respond according to your question numbers:
1. To indicate a turn, I use the old car-default if your blinkers dont work: both directions with the left arm (for visibility reasons), pointing straight left if turning left, and when turning right, a 90 degree bend at the elbow point up with fingers. Sometimes I sort of repeat the motion to make clear what I intend. (I personally feel that a right-hand used to indicate a right-turn is useless sense the body can easily block the indication, plus drivers probably look at the right-turn signal cause they think you are flipping them off and then they realize you are turning while appropriately signalling, hah)
2. No LED turn signals.
3. I would consider them if they were thoroughly well designed, didnt require me to carry a battery pack and didnt fully interrupt the aesthetics of my bike (so it would have to be integrated into the bike frame). If I had a cargo-bike I might consider it considering the pace and function of the machine but mostly what I love about cycling is not having to worry about finicky mechanisms needing power or having to worry that a manufacturer has cut corners in production on an item that will ultimately fail due to vibration, moisture or dust.
4. Its a complicated exercise imagining the best way to actuate such a device. Our hands and feet and eyes are already concentrating on so much and then to have to press a button or some how start the signal just always seems futile, althouh perhaps early motorists too thought this way..? Sorry if this isnt much help. But again, it would be a fun design exercise.

Cheers

Thanks, jburnha. Your input will be helpful for my design.

I use hand signals when I know there are cars behind me and I want to communicate that I am slowing down, especially on a left turn with oncoming traffic.

I do not use any LED turn signals.

I think riding gloves with refllective arrows on the top would be great for night riding. The car's headlight would illuminate the arrow and catch the driver's eye. No batteries needed

I gotta vote up the idea of the glove-based signal idea. Aside from the previous problems listed with a bike mounted turn signal, it seems like another one is going to be size. From a car at a distance, two little lights on either side of a bike will probably just look like one light until they're too close for comfort. Putting it on gloves, or maybe a wristband (like those reflective ankle straps for yr pants!) would spread that out and make it more obvious.

This is really helpful guys. Thanks a lot for your feedback. I am liking the the glove idea too.

Here is the issue(s) I see with this;

1. How would you be able to tell the differance between an turn signel and a rear blinkie?
2. How would you wire it and what would you do with the battery(s) and computer?
3. Most of the time the problem is with oncoming traffic not watching you turn not traffic to your rear. You would need these on the front more than the rear.
