Obviously a flashing light is more 'noticeable'. That's why I said a steady light would be more than sufficient. (Not saying a steady light is more visible than blinking).
I also didn't say blinded by the tail light, I said the impressions of getting blinded. So, get your passive thinking but further than your nose is long and think ... for passing cars, I rather have them being able to focus better on the road, making it safer for you and a driver. Even then when the car hits you, SSP, you had your steady light on and you owe them in court anyhow.
Don't take this offensive guys.
I am a very experienced cyclist from the Netherlands and know what I am talking about ... this is what I've seen, it's something I want to show you as a driver as well. I am hoping for a more informative response other than 'I own them in court' this and that.
