I started with one 700 Lumen handlebar light. Worked great in solid at night, but if I tried to use the flash, day or night, it was obnoxiously bright except maybe in foggy conditions. The light flashing off signs, etc bothered me almost as much as others who saw my light. As it got dark the flashing got more irritating to me, so can only imagine what others thought.
I then added a second handlebar light, an inexpensive 25 lumen light, that is really a "be seen" light only. I have no problem putting this in flash mode in the day and could even use in night if I really want to get someones attention. I typically don't use flash at night, but in certain situations I have (usually while passing slow/stopped traffic in the bike lane to try to get drivers attention so they hopefully don't pull into the bike lane or making last minute right turns, etc). In really dark areas I might put it on solid pointed down while my larger light points further forward.
My Main light gets angled up and down and switched between power level depending on the situation. Main reason to put down is to avoid blinding people on MUP, etc. I typically use this in flash in foggy conditions, occasionally will put on solid or flash in higher traffic areas, etc
I now also got a helmet light, light and motion vis360+. This will give me the "high low" that other posters mentioned, as well as give me a higher light in the rear. I can also use it to signal my intentions, get drivers attention, look around etc. I expect I will typically use it in solid, maybe flashing in some situations in the day.
