i also think flashlights with cheap mounts are great along with some reflective clothing.
my trusty front light.
i usually ride in the city where it's more well lit. But this is at one of the night rides where a lot of roads have no streetlights at all. I could prob use more reflective pieces at this ride. But then my front light is 180 lumens so..
on another note. If u do get a really bright light, i suggest to point it downwards a little (like car headlights) so you don't blind people coming at you. If you blind people, they have trouble seeing you too.
