Just keep in mind blinking doesn't help anyone. Keep your front lights solid no flashing no blinking no winking or anything like that it can cause more issues than it would solve. Yes emergency vehicles flash but they are traveling at high speeds going to hopefully save someone and they have sirens and such to alert you it is a danger light no other road vehicle uses them aside from ermergency and police vehicles in an emergency (or running red lights for some police). You are none of those things and don't need to dazzle cars or would you want to as they might be more prone to hit you in that situation.

Also for anyone coming to this thread late, beam pattern is quite important. STVzO lights which are the road legal standard in Germany are ideally what you want for riding around other people/on road/paved trails, as they cut off at the top but give a good beam pattern for you to see. Also brighter is better not for the brightness really but for a longer lasting battery in the solid lower lumemage. Yes sometimes you need a little more light but really having something that lasts longer is always handy.
