Astronaut lights

It would be awesome to have lights in the helmets of the astronauts so that you can have them walk around in the dark and still be able to see. For example I just did a mission to the dark side of the moon and my astronaut could only go so far until it was pitch black. You have it so that you could turn them on and off the same way that you turn the jet pack and grapple hook. And your astronaut could have a battery like they have some fuel and it would charge the same way there packs refuel.
