Query: Perfect for walking

I live in a neighborhood with tree lined streets and few sidewalks where most drivers are respectful but others feel like you are invading their space and are not shy about making this point by driving too close to you. At night this can deadly. I walk for two hours each day. So I have put these little guys through the test. These lights are great. Just clip them on your clothing and go. They are not so bright that they blind an oncoming car (no point in pissing off or blinding someone behind the wheel with laser powered spotlights :-)) BUT they are bright enough to be seen blocks away. The only caution I have is during the holiday season when everyone has Christmas light decorating their houses... These little flashing red and white lights can then act like camouflage blending you in with the rest of the display. Ouch!
