Tail light for daylight use!
At 40mph a car moves 880ft in 15 seconds! I was almost ran down by someone in a lizard brain trance on dark winter day. I had flags and even a slow moving vehicle sign on the back of my recumbent trike. They did not see me until I moved to get off the road, then this person swerved around me so hard they almost lost control of the car.
After that I started thinking about how bicycle tail lights are not noticeable at 800 ft in the daylight even if it is foggy. So eventually I got this truck tail light and found a battery pack on Amazon, very cheap. I am thinking about putting an LED light strip on my bike to use at night because this tail light is too bright for night use.
I hooked it up with a LED flasher so they really notice me.
