Yeah could be. There was a time when LED lights were not allowed in the UK. Then flashing lights were not allowed. I think both are accepted now. I used to know about this many moons ago as a trained bicycle mechanic but now not up-to-date with the current light laws of the UK. Personally, as a motorist and a cyclist, I prefer flashing lights - it distinguishes a cyclist from a car/motorbike. A reflective top/vest is important for dark roads too. It’s all about being seen. However, that all changes if you actually want to light your way ahead (need more specialist lights for that).
