I am back to running retro lights since my last bike got stolen with the more capable modern lights on it. For now, it is just a case of being seen on the road, not seeing on the road, so it's back to the early flashing Cateye led lights.
A cateye TL-LD260 at the front and a transparent cateye TL-LD250 BS with the expensive N type batteries at the rear, these I got around the late nineties.
Also a weird older something, about 2 x 1 x 1 inches in dimension, quite possible a very early cateye as it is more reflector than light, but it has four flashing modes and clips on via a pen type bayonet, to what was a fabric type mounting but that perished ages ago
The past, my past as a youth, was dynamo lights, the type that run off the tyre wall, later, wonder lights, but the memory is night riding was an expensive game back then if one wanted anything other than 6 volt Union dynamos, that went out when one stopped.
But, ha, the youth of today and indeed those riding in the nineties and beyond, they don't know wht it was like with what we had to use before the mountain biking fashion and actual use accelerated the cycling scene and brought if from what was cheap transport for most and the nerdy eccentric or a sport for the few to what it is now, widely accepted and mainstream part of life.
I still want to see lightweight integral generators incorporated into bikes to run such things as lighting and whatever else a bike may become.
