I'm Right near the coast, this spring I snapped up a Bike friday with disc brakes
and an IG hub, hub dynamo light, I just fitted a wired front, battery rear.

Low mounted the lights, so when it gets Xtra-nasty, i get out the rain cape.
so higher light placement would be under the cape.

still have my older setup an 80s mtb, with studded tires, and drum brakes.
it gets used when the roads ice up.

it does that occasionally, eastern inland air mass pushed out the Columbia valley.
