I came across someone riding an upwrong today that had a quad amber headlight on her bike. It did seem much more noticeable to me that a standard headlight blinking. I don't know if that was because of the color or just because those 4 LEDs make for a bigger looking light source. It's a lot of money for a headlight that doesn't help you see at night, but I like being extra visible with all of the distracted people out there. I've thought about buying one before, and now that I've seen one in the wild I might just pull the trigger and get one.
