CaptMike: I believe I have had mine on the brightest on off flash mode. I know it is uncomptforable to look at directly. I don't know how to adjust the intensity of the flash modes up or down. I am considering giving this one to my son and purchasing the new

2023 model with the 8 cell battery for touring. I had to mount the battery on the underside of the top tube this time because the seatpost is occupied by my mini pump.
