Two questions about the equipment Apollo astronauts had while on the
moon.

1) Did they have portable lights? Flash lights, helmet lights, some
kind of light they could use poking around in a hypothetical moon
cave?

2) On the topic of poking around in moon caves, did the space suit
radios act as relays for each other? For example, if an astronaut got
well into a cave so his suit radio wasn't reaching the lander, would
another astronaut's radio act as a relay to the lander and then to
Earth? Or was it just a direct connection to the lander only?
