Stuff is arriving.
The LED flashers and bulk LEDs arrived. Oh, and the body cylinder came, too. I was staring at the package thinking "it looks a little small, diameter-wise", so I looked at the packing list and they shipped a 16" tube instead of an 18". So I'm sending it back. The folks at TapeEase were great on the phone and are cross-shipping a replacement and covering all the shipping costs. Cool.
