Fair enough - my beam isn't quite focused enough to be able to determine a clear 'top', so I just angle it down enough that people coming the other way only go half-blind instead of fully blind...
Also you'll be glad to know I don't use the flashing mode at night. I have used it before during the daylight though, where the steady light is completely unnoticeable despite it being a pretty strong light.
Top of your beam. This does depend on the beam shape, a lot of MTB lights are way too bright for road use and not flat-topped.
I’m glad you dip yours.
I read somewhere you’re supposed to tilt to stop the beam top at 25m.
