What? No rules for safety equipment for bicyclists? You must not be aware of this:  https://www.oregon.gov/ODOT/HWY/BIKEPED/docs/bike_manual.pdf?

And more: "In Oregon, a bicycle is a vehicle by law. When riding your bike on a
road, you have the same rights and duties as other road users. With a few
exceptions, the rules of the road for drivers apply to you. Consult the
Oregon Driver’s Manual to become familiar with these rules." (p. 2)
