I just bought a new helmet that has the size adjustment knob in back. My old one was the type you lifted the latch up and slide apart which gave me room to clip my Planet Bike (PB) Blinky 7. Is there a screw or glue on mount for helmets that I can clip the light on?? I keep a PB Superflash mounted and flashing on my rear rack even during the day time. I add the helmet light when it's still dark out.
