Yeah, that would be pretty cool. But one of the things I wonder about with the integrated light concept is head dissipation. Air circulation around the light would be critical (I think) or something to help dissipate heat would be needed if in a constricted space. I'd think that the brighter the light, the more need for something to help dissipate the heat, and I wonder about whether the heat might actually cause a discomfort for your head. Then, depending on how the issue of heat dissipation is dealt with, if you have a big chunk of metal to help with the heat dissipation, then you're back to the concern that some have expressed about the metal potentially causing further injury in a crash.

But then again, if the design were cleverly implemented to have a bright light with good heat dissipation combined with design that takes crash safety into consideration, you'd end up with the best of both worlds. But you'd also likely be very limited on choices of helmets and lights (not as many helmets to choose from that fit you well, and probably not very many lights to choose from).

But it would be nice if at least one of the helmet manufacturers and one of the light manufacturers would get together and come up with something that looks sleek and cool and is functional.
