This sort of thing is why we have laws about riding a bike at night here. A you must be wearing reflective clothing, B your bike must be fitted with reflectors and lights (typically people get once that flash rapidly for the rear of the bike so as to easier get attention) and unrelated to the night riding laws but relevant to bikes in general, they just introduced a law that in areas with a speed limit over 60 kph drivers must pass cyclists with a minimum of 1 meter between them and the rider.

All this stuff is quite frankly common sense really.
