Street maintenance trucks and all such vehicles, at least in Europe, don't strobe their running lights which are constant-ON as on all road vehicles and the strobes are additional warning lights. So they get the best of both worlds.
But for cycling, blinking lights are stupid because you're strobing your only running light you need to see and be seen.
The UK has one quarter the deaths despite having ~3/4 of the population of Germany...
It's expected that if a lot more people cycle, you're gonna have more cycling deaths than in countries where fewer people cycle.
If nobody would cycle you'd have zero cycling deaths, hooray problem solved, you successfully gamed the metrics, if wining arbitrary metrics is the goal.
Was that your goal?
Random numbers alone mean nothing if they're meaningless and out of context. More people are killed every year by cows than by sharks. Does that make cows more dangerous than sharks or just that people are more likely to be around cows more often than around sharks?
If Germany has a higher population than UK, and also a higher percentage of people of that population cycle, then yeah you're gonna have more dead cyclists. D'uh!
Show me deaths per capita and cycling rates per capita, then we can talk about drawing a conclusion.
DE 5.5%: https://ec.europa.eu/eurostat/statistics-explained/index.php...

UK 1.7%: https://www.cyclinguk.org/statistics
Great Britain has half the bike usage of Germany. Germany has 36 million bikers (43% of 84 million), Great Brittain about 12 million (19% of 68 million), so the stats line up more than you'd think at a first glance. The difference between Germany and Great Brittain becomes laugably obvious when you look at the statistics for how many people use bikes as a primary transport method (6% GB vs 21% DE).
That said, biking outside of large cities in Germany is kind of terrible, so I'm not at all surprised about how deadly cycling in Germany, though that may just be my spoilt Dutch take on things.

Blinking lights are not legal according to road code in Germany and I assume many other EU countries nor do they necessary improve your safety.
Yes, strobing lights do draw more attention (which is why they are reserved for emergency vehicles and emergency signaling) but makes it very difficult for the human eye to determine the distance to/from that object in motion on the road if it's always blinking, making their exclusive use on the road unsafe.
That's why your front and tail lights must be in a constant state. It's for your own safety too.
