I used the Take a Look mirror on my old helmet, and loved it. My old helmet had this little black visor thingy sticking out in front that the mirror hooked onto.

I just bought a new Giro Pneumo helmet, and I don't see any way to make the Take a Look Mirror work on this helmet- no visor.

Anybody use the Take a Look on a Giro type helmet? Am I missing something? I miss the mirror! I like seeing cars coming up behind me.
