No mileage today

Did discover that the BLT light in question is a 'Super Doppler DX' and does indeed retail for $40 at Bayview Cycle in North York. The trick is that is has a lens that accomodates all three diodes such as to make a tunnel-like focused beam of light. Kinda steep cost, at least it runs on regular batteries.

Goods news in that the dropout alignment kit is arriving imminently. It also comes with a few bonus pieces such as a derailler hanger alignment dilly-yo. View the park MK-129 here
