    Bright and consistent

    I was unsure if this would be bright enough for commuting to work in the wee hours of the morning, but this light has pleasantly surprised me. I also love that this is rechargeable and fit my old Cateye mount (from 2008!). Customer for life

    AMPP400S - Like It !

    The AMPP400S has: High, Medium, Low, Low with Blink, and Plain Blink. Whatever mode you are in when you turn it OFF, it returns to when next turned ON. For daytime I ALWAYS use Plain Blink for safety, and to enhance my being seen. Modes are simple to change. Mounting/demounting to recharge is easy. Low with Blink works well going around my street light neighborhood. Medium or High I use in darker areas. Am surprised with its brilliant light.
