Usually have my high beam on during the day. Was on a group ride recently and was on low beam. At a stop a friend came up and said I should check my headlight cause it was pretty dim compared to others. Everyone had on their highbeam except for me. so yeah I guess it makes a difference in being seen and strive harder to click it on when I ride now.
Low beam and passing lamps for me during the day. And flash to high beams when coming up on intersection with cars waiting, or cars waiting to enter the road I'm on. Also use the flash on every cage that's signaling for left hander in front of me. That flash has saved me more than once.
