Did I read right somewhere on here that you have to request to have the on/off function for the Allant 7? The manual says you can but my headlight/tailight can't be shut off.Well, I decided to try the ‘blinking light via flashlight‘ test in my house. No blinks. NADA...nothing. My guess is the Trek designers thought we Allant+7 owners just don’t need the same level of safety a blinking headlight provides the higher end Allant owners.
