Since I started using a Planet Bike Superflash Turbo, I've noticed that the ratio of how close cars come to me has flipped. It used to be before I used a flashing taillight and strobe headlight, that only about one out of ten cars gave me enough room that I felt safe. Since using the lights, (on all rides), now only about one car out of ten buzzed me to the point that I want to raise my fist at them and ask, "What the heck?" Now cars either go all the way into the next lane, or at least half way across.
But, I cannot tell for sure if the lights are the reason for cagers being more courteous, or that fact that I now wear a chartreuse cycling vest when on my rides. I started wearing a Castelli chartreuse vest that same time that I started running my lights during the day. For colder weather, I have a Bellwether chartreuse-colored cycling jacket.
Thanks for the tip on the Dinoette 300R light. Yes, expensive ... but I want to live to ride another day. I'll be ordering one today.
p.s. For headlight, I'm using the MiNewt 600 on strobe mode. I had a motorcycle come up next to me asking about it, saying he saw it a half mile away. Couldn't have because of the length of the road I was on. It was more like 1/4 of a mile. Still far enough away that I was seen.
