You have an excellent answer to the question as asked already, but even if the answer is "very few" there are some things you can do to help yourself at such little effort that they're still worth doing (IMO of course). They may also help with scary near misses which of course aren't logged, and it's also courteous to be clearly visible so long as you don't ...
Summary: very few. Somewhere between 20% and 90% of crashes involve a motor vehicle approaching a cyclist side-on (guess ~50%), and somewhere between 30% and 90% occur during darkness (guess ~50%). Unfortunately 40% or more are the result of drug-impaired driving or riding. So perhaps 60% of that 50% of 50% = 15% could be avoided if the cyclist had bright ...
I use one of these for kayaking - I didn't want a gopro sticking out of the top of my helmet and snagging in trees, and I didn't want to spend a lot. It has a handlebar mount but I haven't tried it.
