"Moth effect" - blinking or steady tail lights?

[Owlie]

I split the difference. I have a tail light that has a setting that gives both a flashing and a steady red.

I have a Dinotte..... it doesn't simply ask drivers to move over... it demands they back off.... (honest - the difference when I'm using it is noticeable), but I agree. I use both flashing and steady lights. I like to use multiple head and tail lights in any case as I can't always be sure my batteries will last....
