I don't know of the late model (>~2005), that doesn't have a (high) center mounted rear brake light that flashes (blinks) upon activation, before settling to a steady state. Motorcycles have had, and require this type of brake light for decades. Motorcycle headlights often have a 'pulsing' function to increase the visibility of what is an already bright light. Speaking of bright *cough* car headlights have been getting so damn bright that if you think a solid red (or white) bike light around an inch in diameter is going to stand out. Well, I disagree. It won't. It can't. But that's not why I flash. There is no argument possible. The runtime of a taillight that blinks is at least 3x that of the same light on steady red. I need that runtime. And I'm not going to be shamed into trying to behave like an automotive vehicle, which I am NOT. I know, I know, that's what the DOT tells you. You believe them? You really think 200lb+ of bike and rider makes you ... a vehicle? I snort in your general direction. You (cyclist) are at best a sort of superpedestrian. You are VERY vulnerable in the roadspace that you are legally required to operate on. A cyclist that understands this doesn't need to be lit to the nines to be safe. There isn't time to go into the details but suffice it to say that there is much more to it than just being brightly lit to keeping from becoming a statistic. The o.p. is well intentioned but the digression into a "to blink, or not to blink, that is the question", soliloquy is not helpful.
