I'm a cyclist myself but find these suggestions less than helpful. Want to make travel safer for all? Then you need to separate and prioritise the different flows as the Dutch have been doing for years and more recently the Danes in Copenhagen. Bad news: it usually means more street furniture to keep the flows apart.
As for lights: my understanding is that Sodium lights are very efficient because they're single spectrum, which is why they're still being adopted for road lighting even though LEDs are much cheaper than they were. I'm not an expert in this field but I seem to recall an article on El Reg about them being rolled out in Canada as low power and low maintenance.
