This is likely because either the people who own them really don't care how visible they are or don't realize that when you turn a light on with half dead batteries that the initial output will still look pretty good ( which can be misleading ). Ten minutes later when riding down the road the voltage sag on the half-dead batteries will kick in and the led's will barely be lit. Cold weather will cause this to happen sooner. If you use a cheap blinkie best to use rechargeable batteries and recharge them every couple weeks or so ( if you are a frequent night rider ).
