Car lights put out far more than 1200 lumen. Why would a bike putting out that much be dangerous? If it gets you seen, all the better. Additionally, in an urban setting, your lights have to compete with all the other ambient light. Why limit yourself to a
'excuse me...over here' light? For urban riding you need a
'Hey, Stupid! Watch were you are going!' light. Often times, blinding the driver is the only way to get noticed.
