So this super DE-duper company sent me this cool little bike light. I am not sure if it is an upside down heart or balls..lol!!! Either way I am digging it!! The silicone light attaches to the back of your bike and has two settings. The first setting just lights up the second setting blinks.The bike light is water proof and really helps on a serious note it illuminates you so oncoming traffic can see you from the front we have alot of Amish out were I live and those country roads make me nervous this would be perfect, not to bright but bright enough to be seen!!! The fact that it may or may not be balls on the back of your bike is just an added plus!!!!
