Show me your quick release gear that allows you to remove and reattach your bicycle accessories if you have to park your bike in a theft or vandal prone location.

I'm thinking of the bike computer, blinking lights, head light, toolbag, tire pump, and so forth.

With all the talk about parking in malls and walmarts I'm thinking I might need to find a locking trunk for the bike. The more I ride the more of an issue this will become.
