New front light = Lazer beam of DETH
How things move on. My first non-wired-in (i.e. not connected to the bike's wiring loom) front light was a Cateye Stadium. A large water-bottle-shaped battery, then a voltage converter, then a huge lamp unit that wouldn't have looked out of place on the front of a USAnian wood-burning steam engine of the 1860's.
Then I downsized to a Cateye Doubleshot. This time a battery pack velcro'd to the frame, and a co-ax wire with bayonet-connector. Very damage-prone (which is why I've bought its replacement), but the light unit itself was very reminiscent of Johnny 5 (or Wall-E for the younger generation.)
New one is Cateye anyone see the pattern here?HL-EL610 singleshot. Now no wires, clips into the same bracket that's on the handlebars (or nearest equivalent) of all my bikes, eminently pocketable without having to undo wires or velcro.
