I don't see a chance that this would be legally allowed on over-regulated German streets. Quite a lot of good ideas regarding lights on bicycles are banned in Germany, and remain to be banned. Early this year a small mini-reform of the laws regulating bicycle lights has been messed up as well. They wanted to - finally! - allow battery-powered lights as the only light source for non-racing-bikes (in Germany, every bike from 11 kg on must have a frame-installed - non-removable - light system with a dynamo), but somebody wrecked the wording, and due to a small linguistic detail, battery-lights still are formally banned for non-racing bikes now, with politicians refusing to correct the mistake. Thankfully, police controls use some healthy reason on that detail and do not complain about battery lights. But blinking lights of any kind, and picture lights like this one - that is something different. Telling by repeated experience. German traffic cops HATE blinking lights on bicycles.

Even the brightness for lights was regulated and kept at pre-WWII-standards until recently. Not that the police cared in practical controls, but that was how the laws were: your light had to be dim. Formally, the brighter lights of the recent LED-years and stuff used in other countries, was - in parts still is - banned in Germany.

Using bright high quality normal-design LED lights myself, plus a battery backlight on the backside of my my coat's collar. That way you become earlier visible to traffic in your rear sector when the rest of the bike - and so its lights - still is covered from parking cars for example.

Lights to the side or running lights in the wheels are getting the police's unwanted attention.
