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.

Pretty much any computer/lights/pumps will all come with a very easy quick release that leave the mount on the bike, but takes the actual item off. Most bags are a little more permanent, but I'm sure there are quick release models available.

I have a Topeak MTX rack trunk - when I park my bike at the garage at my office, the GPS and rack trunk always come off. If I'm riding with headlights, I bring in the batteries with me.

Usually I just slide my computer out from the mount and take my handlebar bag in with me. My light (as of tonight) will be hard mounted, since it's hub driven. I'm putting my rear rack back on so I can use the bucket panniers I'm making this week, so anything that needs to come off the bike will just get thrown in the bucket.

(Thanks to donnamb for showing me the awesome utilitarian power of the bucket panniers)
