With adding HB Junior 40/30L sidecases I figured it was a good opportunity to add some more visibility. I think the headlights are very good on the bike so I tend to ride more at night. This past weekend coming home through a wicked rain storm I wished I had a little more visibility in the rear. I always wear a safety vest at night, but a little more help is always good. Some 3M reflective vinyl on the cases should help. Another Strommer had done this on his 40L cases and I thought they fit the look well.
