You just have to have eyes everywhere and expect the unexpected. That is about all you can do. If they don't see you I don't think that any number of extra lights or florescent jackets will make any more difference.
I have seen a number of bikes with pulsating headlights and pulsating brake lights. I hate this, as when you see a bike with pulsating headlights coming at you the first thought is that it is an emergency vehicle. Regular headlights work so why try to tweak it.
And pulsating brake lights gets the driver that is behind you accustomed to seeing a bright dim frash, and when the bike rider puts on the brakes it takes a second or two extra for the following car driver to determine that the brake lights are not just flashing. Sure, it is his fault for running into you - but you can still be dead.
Just my thoughts!
