Daytime visibility - I know this is slightly off topic since it has nothing to do with lighting but: my experience both as a cyclist and driver is that jerseys in bright solid colors are seen. Dark is often not and patterns, even really bright ones, often disappear. I wear solid yellow and orange (and white but my experience is that white is nowhere near as good a lot of the time) jerseys most of the time simply to improve the odds that I get noticed. They are the only thing I have done in 50 years of cycling that has drivers coming up beside me in daytime, rolling down their window and thanking me.
