I've always worn a Hi-Viz jacket - but how much of it is actually visible from the front is debateable. I have the Bikequip reflectors on the fairing sides, some on the panniers and a high level tail stop LED light on the Honda top box. I believe that they all help me to be seen, but I don't know that for sure.
I am completely undecided about the benefit of bright driving lights, but so far have chosen not to fit them. I have ridden with other riders who have really bright lights and what I see prevents me from fitting them myself. They seem to hide the bike behind an intensely white glare, which makes it difficult to see what is causing it, and more importantly, makes it impossible to determine the speed or even whether the source is moving or stationary.
The two most useful things for being noticed I have found to be:-
* moving my road position so that I cross the driver's line of sight, or weaving a little;
* and looking into their eyes - its surprising how effective this is when riding a pushbike, and I'm more surprised that it works when riding a motorcycle as well - but I ride with my visor up much of the time, so its easy for them to see that I am looking at them.
Another useful tool is being aware of driver behaviour and that the space that I occupy on the road, can, under certain circumstances, be seen as a space rather than as a motorcycle. My job is to do everything that I can to make sure that I am not occupying the 'space' that the driver decides to move into - and to be able to spot the circumstances when this can happen.
Sometimes as motorcyclists, no matter what we wear, no matter what lights we have on, we can be quite skilled in making ourselves invisible. And that can be less to do with 'brain dead drivers' and have more to do with motorcyclists being unaware of their own 'transparency' to other road users.
And before you all shoot me down in flames - consider this. We don't see what our eyes see. We only see what our brain tells us that our eyes can see. If for whatever reason, our brain decides that something in our field of vision is not important, then we don't see it.
