Thanks gentlegreen.
Saw your lights in another thread. The page describing your path was should I say -enlightening.
Police here are so happy you have decent bike lights (not Ninja) they won't quibble on brightness.
I saw a trike that had a rear light with about 40 LEDs and it was pretty impressive. I followed him on the last leg of an exceedingly windy 75 mile day. I thought a decellerometer to drive increased current so the faster he slowed the brighter the light would get would have been a nice feature, but maybe I was following a bit close.
You mentioned a distaste for flashing lights on your link. They give me a headache if bounced back at me. Here, flashing lights on a bike are essential to have any right of way at all. I also run my headlight (no flash mode) in the day as a daytime running light and moved ligths on to the helmet to be more visible over cars. This has cut my close calls by inattentive drivers a lot, I'd guess it at 80-90%. Very apparent. Very good. Eternal vigilance! Flashing lights don't fix stupid.
I will be giving a version of your multiple red LED rear light some thought.
