Bike shops in New Zealand stock carriers and lights (of course) but not the brackets such as this
My rear light comes off if I go over a bump. I was going to order one from Amazon but with postage it came to about $50 (they use a large bag)!
Planet Bike in the U.S sent me one free! I explained about the cost for postage etc and they said that as they weren't set up for foriegn purchases they may as well just send me one. Thanks to Planet Bike!
It's on the top peak carrier on my Surly LHT.
