The Biologic TailLight safety light is a combination LED light and reflector that snaps easily onto the rails of any standard bike saddle — no tools required. This rear LED light for bikes sits up high so it’s more visible to cars coming up from behind and the bright LED light features both blinking and steady modes.

    (verified owner):

    Very nice tail light. It fits firmly on the saddle, and can be removed very easily.
    I use it flashing to complement a continuous rack mounted tail light.

    I like this rear light. It is simple and despite the single LED it is bright enough.
    The thing I like most about this light is that it doesn’t take much power at all. I’ve been using it for the last 5 years and yet to need to change the battery

    Very thoughtful. And saved me a few dollars more!

    Took a few seconds to fit and does a good job.

    Light and simple. Easy to fit without any adjustments. I can imagine a little bit thinner construction using AAA instead of AA batteries and/or larger LED (or more LED) to increase visibility. But I am very satisfied with this product as its.

    Fit the seat on my Tern C7. Light is bright in flashing or steady mode. Easy to remove to put in your backpack so it won’t get stolen when the bike is locked up in town.

    The “light” part of this safety light is the small LED between the reflector and the on/off button. It is intensely bright and satisfies legal requirements for a taillight, but this product might better be labeled “reflector with red LED.”

    The snap-on mount works OK but I had to slide my seat back two-thirds of the available travel to mount it. This lamp (including the battery case on the back) requires around 3/4 inch (20mm) of level seat rail space.
