Hello,

I hope you don't mind me chipping in with this. I can remember a while ago coming up behind a bicycle in my car at night. I was away from bikes and LED lights were a new thing to me. I passed by a rider with a flashing red tail lamp and it was blinding. I love bikes and I share the road, but getting flashed in the eyes is not a good thing and you do not want to know what I thought of this person with that lamp. No, it was not safe that I had to blink and avert my eyes. Yes, it was that bright.

Just note that when you program/aim your lights. Food for thought.
