Besides the fact that they're blinking lights so only on 50% of the time by design, consider the fact that regulations specify the minimum luminous output which these cars obviously pass. Add to that the fact that you're using modern high power LED lights and that the human eye perceives light in a logarithmic manner, it wouldn't surprise me if these indicators will be more noticeable on their "minimum" output than their old incandescent bulb counterparts.
