How does the light itself compare to the other Toplight and perhaps Superflash or Radbot 1000? I currently use a battery-powered Toplight 4D which I like but it gets really dim in cold conditions, and wouldn't mind doing without batteries altogether. I guess my question is which dynamo-powered Toplight is best?
Thanks

Well, I finally got back to installing the light we have been kicking around awhile. I was out of town on some urgent family business, but it was waiting for me when I got back. I figured if it worked for me it would work for anybody, I use a Spanniga tire driven dyno. Wrong brand, ancient tech, no latest greatest nothin'. The damn thing works, very nicely as a matter fact.I posted a review on my blog and I am really glad I bought it. $20 bucks, hell yeah!

4D toplight senso plus is wired, so they run on the Dynamo,
when the headlight its wired to is on, so fixes your cold battery problem
But the batteries are still there .
Senso mode with the headlight off, taillight on 3rd switch position
but in daylight, not lit, then..
their tunnel light function kicks in when needed, a blink mode,
then off back out in the sunlight . That runs off the 2 AA.

You gonna eat that?
Ack. Now I really really want this. I guess I need to put this in the queue of bike stuff I need.

In the right lane

I've got that taillight —*got it about a year ago.
Knew it had a standlight (stays on for several minutes when bike is stopped) but was unaware of any brake-light function.
Maybe that's a new version.
That said, it is an excellent light. I had an experienced cyclist comment on it the other day, after he came up on me during an early morning ride.

Interesting that it uses dynamo frequency to determine when the bike is slowing down.
If anyone's interested in a DIY brake light, I've been experimenting with a microcontroller-based speedometer for my hub dynamo testing. I thought it would be tricky, but it was really just a matter of pulling a signal off the AC side of the bridge rectifier and connecting it to the input of the MCU through a resistor. It essentially works as a zero cross detector and all AVR microcontrollers support it. There's even a handy little application note about it. To calculate the speed you just count the number of pulses in a fixed time. With pulses/unit time you can determine the speed knowing the wheel circumference and dynamo pole number. Deceleration, as mentioned already, wouldn't require knowledge of the dynamo pole number.
My implementation uses a big clunky Arduino, but a smaller AVR chip should do the trick.
Maybe one day B&M will offer a dynamo-based speedometer!
