Well, I ride that bike path pretty much every day (and night) these days and I agree with him. I think what we're talking about is not necessarily every flashing light just the ones of extremely high wattage and lumens.

It's appreciated if you aim them down and keep the real bright ones on steady while on a path. If that's just way too much for you then so be it. I'll watch for you as you're coming down the path and make sure to have my sunglasses handy to accommodate your very special needs.
