There seems to be a mindset that that is indeed what
bike riders need to do, either in terms of o/p wattage
or brightness. In city traffic, blinking lights + speed
difference + positioning on the street does the trick
nicely -- as long as the batteries don't fade.
On lightly-driven country highways at night, just about
any kind of light sticks out like a sore thumb.

It's very nice to be able to cast a luminous spot on the
city streets at night when approaching intersections in order
to announce one's approach to any possible cross traffic;
epecially at blind intersections, which should be dealt
with gingerly anyways. 'Cuz chances are, any cross-traffic
drivers there won't be alert to the approach of car
headlights, let alone bike lights. So we have to be
alert for them.
I guess just having lights on is no excuse for having
one's guard down.
Nothing is safe from me.
