Tail Lights and Auto Settings
Last week the Co-Habitant installed the Spanniga Pixeo tail light on his bike (very thorough review of this light here) and set it on auto. Cycling together later that evening, I switched my own lights on when dusk fell. As I rode behind him, his Pixeo tail light would switch on and off in response to slight changes in lighting conditions. For example, as we entered a stretch of road with fewer trees, it would switch off; then on again when the trees became more dense. Not only did I find this annoying while cycling behind someone, but I was also surprised that the light did not "think" it was dark enough to just stay on the entire time. It wasn't quite pitch black, but getting there. I wonder how the settings are configured, and whether they can be adjusted.
