It's a bit frustrating suffering from insomnia and being so dark in the mornings now...
I've got the same problem, only at the other end of the day! I am often not getting to sleep until nearly 05:00 and then don't sleep well, so I am knackered when I finally drag myself out of bed at 10:00-11:00 and do not feel like immediately going out for a bike ride.
I often leave my rides until the evening, which is really nice in the summer, but the nights are drawing in now. I went out at 18:30 yesterday and the light was already fading as I headed home at 19:45. I switched my front light on and reached round to do the rear one, only to find that it had fallen off! The lights were Lidl bargain buys, little
be-seen-by LED lights with stretchy loops to attach them to the bike. I had damaged the loop on the rear light and had anticipated that it might fail so I had added a rubber band for extra security. Next time, I will use a
stronger rubber band!
I dug out my old head torch from the back of my spares drawer. It has an optional red light so I will use that for a rear light until I buy a replacement for the lost one.
