-Do any of the lites listed above have direction indicators (turn signals)?

i have a planet-bike front lite that i mount under handlebar bag. it's about 6watt +/-, battery powered. i also have planet-bike rear lite/ blinker along with 3 or 4 blinkies you attach to clothing etc.

even though the front lite is not that bright, my current concern about winter - nite commuting is:

- How does everyone Signal to drivers when/where you are turning, left or right and stopping? (hand/arm signals don't work, it's too dark!) -

thx!
