I picked up some of these $1/each, but never got them working.  I'm assuming it's a flasher issue, but not positive.

What are the symptoms ?

If i remember right, they didn't light at all.  My current setup includes new LED rear signals (housings with integrated LED bulbs) combined with the stock front housing/bulbs.  It blinks fast, but works.  When I switched the above LED bulbs into the front housings, I would get nothing (no blinking front or rear).  I tried a new LED-compatible flasher, but it didn't help so I gave up and left the stock front bulbs in place.

Led have polarity, while bulbs do not. It is important to get it right otherwise it is an "open", they are diodes.

That should be easy to test. Just connect one to any battery 9-12v, and if it doesn't light up, try switching the polarity. Chinese unnamed brands often get this wrong.

Its blinking fast because there is insufficient load on the flasher unit, you'll need to put a fairly hefty ballast resistor in series with the LED indicator unit.
I had to do this on my old Zero S. Frankly LED flashers are not worth it, with the ballast resistor they use as much power as incandescents, in the end I switched back to normal bulb indicators.

About 30cm of range I guesstimate...

Hey, if it's not the extending the range much, it does give the bike a more modern look right? And that last 30cm will get you riding into the garage instead of pushing 

That's pretty much my take on LED turn signals. It's not about range extension (it isn't really worth talking about), it's about a better look, sharper operation (LEDs don't "bloom" on and "fade" off like incandescent light bulbs, they snap on and off), and just generally customizing your bike to be unique. Longer bulb life is also a good thing, and what's wrong with saving a watt-hour or two?

Here is a review on Webbikeworld.com of Weiser Ultrabrights. It lists Zero as one of the applications. No need for load equalizers, plug n play install (10 mins for a pair), http://www.webbikeworld.com/lights/weiser-led-turn-signal-review/
