I used the reflective pin striping on our bikes and on my helmet. The pics below show the reflection by using a flash.


In addition I am wearing a high visibility vest above my jacket. The ones you get for under $10 at Amazon.

Get the vest one size larger than your jacket so it fits on top of a thicker jacket. The Neiko vests are available all the way up to size XXXL.
And I also have the spoke reflectors which I still need to put on.
