A Bontrager Ion 200 just to have in case I get caught out after dark. The additional visibility is good, but mostly I need a token light to comply with law. With the time change coming up I just want something small that can go in the seat bag or my backpack for commuting, without carrying my rather largish Dinotte kit. That stuff is still vastly superior for actual illumination, but overkill to always have on hand over winter. (Why didn't I get something like this sooner? Doh.)
And a new pair of fall/spring cycling gloves that at least try to work with smartphones. (Assos intermediate.) That's mainly for road use, but I'm sure they'll be nice to and from work, too.
