I bought the "wired" 12V Lightman strobe (in amber) a year ago for my homebrew light system. Its 5-sided connectors mate perfectly with the ones I cannibalized from my old TurboCat system, by the way.

I ran with it for a whole winter, but after doing a visibility audit on myself (parking my bike with everything on and confirming visibility from different angles and distances) I took it off. It's underwhelming, at least in amber. It gives off more light towards the sides than my headlights, but really no better than a good LED blinky. And on-axis it's LESS noticeable than a decent blinky once you are a block or more away, and not even close to the conspicuity of a 20W headlight. Will probably sell it at some point.

I'm sticking with LEDs. I've using some very bright automotive LEDs as running lights, and will probably add some flashing ones too. I wish bike light companies would make blinkies in amber. The LEDs are available, but for some reason commercial blinkies only come in white and red and these days.
