I'm not really on-topic, sorry. But I'll throw this out for the sake of safety.
I've found that the best setup is two cheap lights front and back. I did it mostly for redundancy, but I've also found that the two lights up front give me a better view if one is aimed just a bit higher than the other.
I experimented with lighting in the past, thinking "the more the better". But it doesn't seem to work that way. Too many lights in too many places just seems to confuse drivers.
So on the rear I merely use one light. Though I'll turn on the second one in blinking mode in poor visibility conditions. (blinking also seems to confuse or partially blind drivers, so I don't do it in clear conditions) I also wear a reflective safety vest. That made a huge difference. Drivers understand exactly what they are seeing from a long way off.
In short, basic lighting with the safety vest seems to be, by far, the best set-up I've found. Cheap and easy, too.
