Someone called recently asking for suggestions about what to do with the Cyo tailight wiring connectors if you’re not using a tailight. Unlike other dynamo headlights the tailight connectors for the Cyo are not connected to the headlight body, but attached to a few inches of wire. If you’re not using a tailight the stray wires look a little ragged.

One fix is the take a piece of heat shrink tubing and sleeve the connectors with the main headlight wire. Apply a little heat and you’re finished. The wires are tidied up and you can cut the heat shrink off with a razor to connect a tailight in the future.

A couple of announcements about the excellent IQ Cyo lights. After being out of stock of the black Cyo’s for a little while, I now have a small shipment of the R version Cyos, which will be all I have until the end of January/beginning of February (fingers crossed). However Busch and Muller have released a silver Cyo, which I have in both the R and regular version.

The bad news is that the silver Cyo’s are only produced in the senso version of the light. The senso version have a third switch position (on, off, and senso) in which the light shuts itself on or of depending on the light conditions. Personally I find this setting useless and it makes the lights cost an extra $10. However, some people like it, and even more people (myself included) have a weak spot or shiny silver bicycle parts.
